Y-Pipe Group Buy, most likely to happen!

[CRMB]

The design was based off of the stock pipe. We have no way to do any other design criteria without a truck. This has been the problem all along. I can't alter the dimensions outside of what has been test fit, and there we carefully fixture from the stock part as to not run into boundary collisions. It's not like we can just fudge the collector back a bit and just slightly change angles. This process has been done blind. We can build any pipe we have a design for, thats what we do, but getting the right pipe is the trick here.

Completely understand, I really hope to see this go further, big market on here for it, good luck guys I'll still be around to see more advancements.

Would adding a pc of oval tubing where it crosses over the trans
instead of a round pipe make any difference as fas as road
clearance ? I know Spintech sells oval transitions.

Roughly how long would you need a truck at your shop to fab up a prototype? I could probably get a few days off work and offer up my truck for fitment if you guys could cover my travel expenses...

likewise, I love driving, it's no big deal to me. Pay for the gas and shack me up someplace. I'll actually be up in Oregon next week and then to Seattle. Unfortunately, it's by plane lol.

The installed pictures are VERY strange to me for some reason. It looks like it sits really low, like the down pipes are too long. When I go to install mine, I'll go over as much as I can just like DiCi. If there is room, I'd rather cut some of the manifold flange side to raise the Y pipe up some, tuck it up nice and make room to go over the cross member. I don't know what happened, this is a set back, and it seemed like the prototype fit.

People are already running with their tails between their legs. No one (but Whitty) sent in info for this project. It's a shame everything doesn't go smoothly, like you want it to, but how often does it? When you buy a tried and true product and give them a thumbs up, that's because somewhere in the beginning it took enough people willing to be test subjects and a strong company to deal with all the thumbs down.

**Mikz86TA----is it possible to unbolt that pipe and send it in? If you get a stock replacement for now?
**DiCi21-----is the slip joint where the two down tubes come together welded? It looks to be without weld or a clamp. Dunno. Also, thank you very much for the drawing, pictures, and discussions thus far. While you have had to endure some troubles, I speak for at least myself when I say thank you, it has helped. I am determined to finish my own Y pipe. Once it's done, I'll prolly send CRMB my stock Y pipe with pre-cat attached.

For those of you needing ground clearance, this is a special project for you. Someone needs to come forward with a truck or aftermarket Y pipe for CRMB to take measurements off of. I was never in this for clearance, only performance and to get rid of my pre-cat. Hopefully it yields decent results. My truck is a zq8 and I have a quad, so it sees off road QUITE a lot for being lowered, I get high centered and stuck a lot. (yes, I also installed a recovery hook on a lowered truck lol) I don't want to spend the money lifting a 2wd, so hopefully the Y pipe can suck it in enough not to cause me trouble.

For not having my hand in the cookie jar, I sure do work at this a lot.

Adam, how about doing.....

Oval Tubing .......performance AND clearence. Should solve the problem for the picky customers.

Some of you guys are WAY too low. I have 4/5.5 drop and never drag my stock pipe, which hangs MUCH lower than the CRMB pipe and MUCH MUCH lower than the classic SLP Pipe.

I scrape mine a lot, I'm bagged so I ride real low I can easily solve my problem by airing up a little bit but hey who does that I'm going to see what direction CRMB takes this...

Is there a big performance difference with this y-pipe installed??

[Bruizer]

I would love to have one of these for my '04 Blazer ZR2.

I built a downpipe from scratch for my girls 02' Xtreme awhile back. This is pretty much how I did it. Here some pics.





And here is how I mounted up the muffler.



This entire setup consisted of removing the first cat, keeping the second, a custom dowpipe, a Flowmaster muffler single in, dual out and also kept the two bolt flange where the merge meets the cat. She never scraped once anywhere.

This is what I was thinking as well. I would of gone this route if the downpipe I made for my girls ride was scraping everywhere. It didn't so I left it. Maybe for guys that are lower than a ZQ8 model would need it though.

[CRMB]

Oval tube is extremely expensive and not something we are tooled to bend, it's not something we would do.

We need a truck for the better part of a day. It's hard to see what needs to be done without having a truck here. I also think that for the clearance guys, you need a much smaller pipe (maybe slightly larger then stock), that just stays above the frame rail. That will never happen with 2.25", but it could with 1.75".

1.75" is fine, we(clearance seeking people) dont care about increased performance. Stock size is pefectly fine. just make it and we'll buy it. But yes i know you really need a loaner truck

Funny you should say that. That is exactly what the muffler shop here said about a y pipe.
it needs to be extended to the rear of the tranny. There is room there for the pipe to "tuck" and get more ground clearance.

[Mikz86TA]

Psycho : I think it could be possible for the crossover to be a bit farther back. But keep in mind there would be a upward and then an immediate back bends. So that would be tight. Getting some pre-bent mandrel 90* peices or u-bends may be an idea to mock it up. Keep in mind that my pre-cat used to be just in front of the crossmember where the y merge is. Ill try to get a better picture where you can see over the crossmember sometime.
BlackBowTie : I really dont have the time to do a swap in-out. I still got the stock y-pipe but we cut the flanges off to use on this one and it was also cut at the back of the pre-cat since there wasnt a flange there. So its not possible to reinstall. IDK why I even kept it.
The only possibility I think would be is for me to go and have another one made by the guy who did it on my truck after removing this one. Then I could send one in for whoever is going to copy and reproduce it. But they would have to pay me up front the cost that the shop charges me plus shipping. Thats probably more money out than they are intending to make on the resel of each pipe. IDK. Either way, I really dont have much time at this moment. I wish I could help out tho. I had searched for 2 years for a SLP pipe and it was frustrating. The shop that had made this one for me was the only ones who would do it around here too. I know from the past there is alot of guys who cant even find a shop where they live to cusom make one either. Very frustrating.

[rentedmule]

I'm still interested and it's definately not for clearance reasons. If I wanted a stock replacement pipe I'd just get the magnaflow version.

My truck is stock ZQ8 height and the pipe that's pictured would scrape on everything. It looks from the pic that there is room to move it up quite a bit and run the pipe over the cross member instead of under. There's adequate clearance on the pipe that Mikz86ta pictured and his truck is a 5 spd - there's no reason why this can't work, we just need to get a truck to CRMB so they can do it right. We have to appreciate the effort CRMB is going through to get this done - I don't want to leave them hanging after all their work! If we can get it right they'll sell alot of pipes

[bg's]

Or maybe something like this ?

[Rompn]

You definetly gain clearance going towards the rear of the tranny rather than the front like they are being made now. In my set of pictures for the one I built, you can see much better clearance where I put it under the tranny. I was going to put the crossover ALL the way behind the tranny but the bend then to go towards the rear of the truck would have been really extreme. I used 2" tubing for the downpipe and even that was a little large I felt on a basically stock 4.3L engine. You would need some decent mods to run a 2.25" downpipe and not loose a lot of bottom end power. I built that downtube setup for roughly $75 and an afternoon of time. I bought everything from Jegs and it was all just 90*'s and 45* bends and one merge collector.

[bg's]

^^ I really like that a lot. It would be perfect for long tubes with just a bit
of modification.

Maybe you could step up to a slightly larger diameter pipe for that section and flatten it out some with a hydraulic press or something. The larger diameter would make the crushed part have about the same cross sectional area as the rest of the tubes

[DiCi21]

So CRMB, whats going on with making that pipe to go up and over the cross-member?

[vstone420]

I have a 2003 ZQ8 4.3L Auto and i live in Portland, OR I might be able to let them use my truck for a few days if i can find a rig to use while they have my truck.

[99xtrm]

I have a 99 so the mock up from the prototype should fit me fine. I am still planning on buying one, but it will have to wait till i get the stimulas check. Thanks CRMB for all your efforts.

[White2000X]

I've been watching this post since it started in hopes to get good sized y pipe that was well made. It looks like CRMB has done it! I havent ordered one yet. I was thinking that you could probably use one of the 2 inch transitons that CRMB sells to get up and over the crossmember. If you got your y pipe made with a slip fit instead of a flange. Just throwing it out there not sure if it would work but from the pics it looks like it might.

nope wouldnt work. the pipe sits too low and at a slight downward angle...the bend to go up and over that crossmember is not subtle at all. and also my ypipe has a 3in flange on it so 2in is out of the question.

[White2000X]

Sorry i ment a 2" offset. So the outlet would be 2" higher then the inlet. CRMB sells them for 37.99 aluminized or 45.99 for stainless. It seems like you could make up for some of the downward angle if it was a slip fit. Still not sure if it would work. I am also planning on running 3" pipe.

[SandBlastedS10]

I'm in Oregon & I can offer up my truck if need be. BUT mine is a 4x4 I don't think thats what your after.

[BLACKBOWTIESS10]

^^ could still be used for the 4x4 version

[CRMB]

The thing I really like about this community is the number of people willing to step up and help get things right. We've got a couple members who are going to be sending us their old 2000+ pipes, and one member who is modifying it to fit perfect and sending us that back. So right now I'm just waiting to see what we end up with and what adjustments need to be made. I've made them unorderable until we get these last few issues resolved though. If anyone has a truck available in the portland/vancouver area, we could probably get these things fixed within a day.

[perfect 10]

Keep us updated, im still in for a pipe!
