Slp Y Pipe Fits Perfect On 99 Up Trucks. Pics Inside!!

98 SS ON NOS · 09-22-2002, 09:56 PM

well only thing you will notice is that on the ones with the precats you can weld it onto the precat but i just took it off.

Well only other problem is that on my 2002 sonoma the y pipe to the header holes on the retainers they are to small. i guess in 99 changed to bigger one cause it fits fine on my 1998. so i just drilled them out a little bigger and bolted up fine.

now tomorrow gonna get a 2.5 pipe welded from the y pipe to the cat and set to go. should sound better and get up better since the precat is gone.

well here are the pics

btw- open exhaust is loud and at the light foot on the brake and hitting the gas sounds like i have a fat duration cam lol

Tony, do you still have the STOCK cat?

98 SS ON NOS · 09-22-2002, 11:23 PM

no i kept the original cat but took the precat out. i remember on my 98 ss when i did the y pipe it got so much deeper and louder.
so this one i have a 2 chamebred non delta with a 2.5 turn down sounds good and since i moved the muffler all the way under the bed it isnt loud inside the truck. if its loud now with this new set up ill just do a 2.5 over the axle and have it turned down after the rear axle

Cool keep us posted, I'm thinking of doing my Y-PIPE too.

Ricesmoker95SS · 09-23-2002, 01:14 AM

will the SLP Y-Pipe work on my 95? and is it smog legal?

98 SS ON NOS · 09-23-2002, 01:33 AM

im not sure if it will fit on a 95. my 98 ss with all the mods i have passed fine for my california smog check up

Ricesmoker95SS · 09-23-2002, 01:39 AM

so it has the holes for the 02 sensor? where do I get one, and how much does it cost? thanks in advance.

98 SS ON NOS · 09-23-2002, 01:43 AM

slpeng.com

they are about 230 shipped and they have the bungs. they come with a flange to cause after i think 99 they started with dual cats and flange is no longer there.

you can go to a shop see how much they charge you to do one or order it test it out see if it fits and if not send it back

Ricesmoker95SS · 09-23-2002, 02:47 AM

awesome, thanks, i'll be getting one of those when i redo my exhaust system this winter

Photo · 09-23-2002, 09:47 AM

Tony, I need info. check on the BLAZER for me and see if the SLP Y-pipe is bigger than a stock BLAZER?

HuTcH · 09-23-2002, 10:06 AM

tony can you check to see if it fits perfect on89-94 4.3's too?

Zombie_97 · 09-23-2002, 02:37 PM

Tony, you have an auto right?

98 SS ON NOS · 09-23-2002, 08:56 PM

it works on 5 speed also just grind the shrouds on tranny.

guys THIS SOUNDS SO SWEET

i got it welded up and you can ask NOT2LOW98 it sounds better than my ss. Deep idle not to loud and just man i cant explain it. worth the 200 bucks by far.

but like i said if you want this set up make sure to have them move the muffler as far back as they can so you dont get the resonation into the cab. after i lower it it will be louder cause the turn down will be a lot closer to the ground. most likly ill just do a 2.5 bend over the axle and have it dumped after the axle

98 SS ON NOS · 09-25-2002, 12:09 AM

danteisme · 09-25-2002, 11:38 AM

sweeet

s10rz350 · 09-25-2002, 03:33 PM

Thanks for the info Tony.. What headers are you getting?

98 SS ON NOS · 09-25-2002, 06:12 PM

headers are a waste of time. if running nos or blower yes but i wasnt impressed with the performance, but with the bottle yes pulled better.

the truck only has 1200 miles on it and have every bolt on cept headers, e fan and igntion which im not doing. im done with it only thing that has to be done is the 2 3 drop and the hidden hitch and assists bags in back to tow my ss. i was gonna go lower but forget it i dont feel like scraping and got my 98 ss for that

btw i got my new rims boyd savages for my 98 ss. they come in tomorrow.. oh wait i mean umm some other rims not those lol heh heh

09-25-2002, 07:46 PM

those rims are badass!

98 SS ON NOS · 09-29-2002, 04:43 AM

UPDATEEEEEEEEEEEEEEEE

VICTIM #1- HONDA CIVIC, INTAKE HEADER AND EXHAUST.

:cry: :cry: I want to see the RACE

98 SS ON NOS · 09-29-2002, 03:23 PM

not2low98 i kinda raced tommy but i think i pulled on him and and then we just stopped. then i raced a buddys x 2 days ago with 308 gears even with 373 on the freeway still pulled on him. off the line was over before it began. last night tommy was in my truck when we raced that civic was pretty funny off a roll was a little closer but as soon as she hit 2nd i was gone. but man off the line i power braked to 2400 and just stood there on the count of 3 i was goneeee ask tommmmy

not2low98 · 09-29-2002, 03:26 PM

man.... you should let me know of this things

I wanted to see/race/lose :bawl2: , that's not for long I hope

98 SS ON NOS · 09-29-2002, 03:29 PM

me and you should race again so you can see the difference with y pipe and programmer. right now i have a prob going into 3rd gear the tranny just locks up the converter then it unlocks. so i took the hypertech programmer out and now it doesnt do it anymore. so i put it back in just to test again and its doing it again. i have to call hypertech and talk to them

tony

not2low98 · 09-29-2002, 03:31 PM

yeah, we should, but in a good area like.....

GREAT HIGHWAY near the ZOO, it should be fun

98 SS ON NOS · 09-29-2002, 03:40 PM

yah but i know you dont want none of this off the line heh heh 2400 rpms takin off with no spin. well do a rollin start again. im gonna take the truck back tomorrow morning for a leakin seal behind the tranny then when i get it back drop the front one day and do the rear the next day. thursday gonna put on the pullies

not2low98 · 09-29-2002, 03:44 PM

HHHHMMMM maybe the 2400RPM stall, it damaging you tranny.

and I want OFF the line 1/4 mile style

98 SS ON NOS · 09-29-2002, 03:48 PM

page me up well run tonight. ill be back at 8. well do a run from 10 mph up so there will be no spin and then well see if the y pipe and hypertech did anything for me

not2low98 · 09-29-2002, 03:49 PM

ok, I call you later

AlpineFX · 09-30-2002, 05:03 PM

Yeah, he fockin PULLLED the civic by like 5 carlenths he was GGGGOOOONE!!! It was a chick drivin the Civic... And I couldn't get the soundclip :-\ sorry guys.

not2low98 · 09-30-2002, 08:18 PM

well, you can't count a RACE against a CHICK!

chick's can't drive.......

hey Tony, sorry I didn't call you, I was busy in the South Bay.

let's try it some other day...

98 SS ON NOS · 09-30-2002, 08:54 PM

she was speed shiftin!!!

the 2nd run when we went off a roll thats when you see whose faster no excuse on wheel spin. so i heard her get into second and the rice boy intake suckin in air but still pulled on her hard

2LO4U · 09-30-2002, 09:52 PM

Dude thats gay. I was walking all over "hopped up" rice cars in my stock blazer, lol

PokerRoo · 11-03-2002, 02:29 PM

Hey Tony,

Just wondering what size I should be looking at for the SLP y-pipe?

2.5"?

I'll probally keep the pre-cat, and get some sort of cat back exhaust in 2.5"

Thanks for any info.

Jeremy

98 SS ON NOS · 11-03-2002, 06:31 PM

its 2 1/4 2.5 is to much i feel on all motor apps. with the y pipe and take off the precat(you can put it bakc on for smog) and flomaster part number 42541 with a turn down sounds bad azz!! im going to run the pipe behind the rear axle this week though a little to loud fo rmy taste

s10rz350 · 11-04-2002, 06:18 PM

Hypertech sucks.. I only use it for a top speed limiter removal now. Cant wait to get my 160 stat the fL|ck out too! POS.

98 SS ON NOS · 11-04-2002, 09:57 PM

well my truck bogs at 4800-5000 like stops then kicks on again. i hvae the granatelli cold air calibrated maf coming. oh the hypertech made a difference for me and with 93 tuning it does pull a lot harder but i want to get 100 octane not some booster in a can and try again

98 SS ON NOS · 12-01-2002, 09:25 PM

guys truck still is fine without the precat no ses lights

Derrick824 · 12-02-2002, 07:37 AM

What is the size of the pipe coming out of the manifolds on the SLP y-pipe? You told me before that blazers already have a bigger y-pipe but the one on my '01 is tiny. Its no where near the size of the stock y-pipe that came on my '93.

98 SS ON NOS · 12-02-2002, 09:55 AM

2 1/4

Hey Tony,

My Truck is doing something similar.

When I punch it from a stop, she'll launch fine, but seems to bog at the 1-2 shift (its pretty early) just for a second, then its fine.

Any ideas?

It doesn't do it all the time though

98 SS ON NOS · 12-10-2002, 02:11 AM

i went to dealer put all the stock intake and maf and tb plate back on and still does it. they have found the crank positioning sensor is bad and gonna look into the bogging

98 SS ON NOS · 12-30-2002, 06:35 PM

sonoma is fixed and y pipe still going strong. we are going to open track teh first and looking for 15.0-15.2 times

wolfmangk · 12-31-2002, 02:05 PM

If I had any money I'd pay to hear that recorded. How about recording it open?

gmczr1 · 12-31-2002, 07:42 PM

hey tony will the 98 y-pipe fit on my 96?
