I have an 96 S10. I would also like to run headers, so what would work with that and like a single 3" ? Can u run that straight back, or do u have to have like some cat-back system to be legal. Im a nebie at this exhaust system stuff so If someone could help, thatd be great!
I'd say go with Gibson headers and then go with Flowmaster from there back. Flowmaster sounds pretty damn good. Also I would go with a single exhaust and not a dual. Two of my buddies had duals on their trucks and it sounded good, but it would've ran better with single. They were both going for look and sound, than performance.
JBA headers have never had a bad word said about them on here, as far as i know. Edelbrocks rust out if theyre not coated. just make sure you get either Fel-Pro or Mr. Gasket header gaskets, or the headers will be off in a month with you replacing the gaskets. a single 2.5" pipe would work fine.
I disagree with the hiflow cat not making a diff. At least on 1st
Gens. I had a factory cat and though it did it's job, the back
pressure came out to almost 2 to 3 #. My ride runs good.
Not as good as it could but it never ran fat or lean save for
an idle misfire sometimes. I stay on it. The orig cat had almost
80,000 on it. I could tell from a smog dyno test it wasn't using
all the o2. In fact it was at 2.43%. I had a Catco hi flow cat
that I had been waiting to put on, just never got around to
I installed the cat, using the same muff. A flow delta 50 and
the same tubing, 2.50 out. After I got the new cat in the sound
was much deeper and I felt it was flowing more. I did a back
pressure test and it came to 1.50-1.70 # at 2000. I then did a
another dyno run and found the new cat was using o2 with
a leftover amount of 1.18%. In fact from having a an engine
that ran HC's at 99 ppm to went up to 123ppm with a o%
CO. So as far as I'm concerned at least on my ride the hiflow
worked and I passed a state of Ca test only smog test.
As far as a muffler, there's better flowing muff's out there than
a Flow. Dynomax Bullets, Magnaflo muffs, and Hooker Maxflow.
However Flowmaster has sold a LOT of muffs, so they must
be doing something right..I have two Flows sitting in a shed
along with a Gibson muff..It to me, flowed the worst. Just a bit
up from the stock muff, I felt.
I'm running a Spintech chambered muff. It's coming off this week
for a Maxflow. I want to go from chambered to a straight thru
design with some quiet to it..However exhaust sounds and
performance I have come to believe, are best left up to the
owner..No one seems to have a definitive favorite. I've
heard good things about Ravin muffs, that's discussed over
at the exhaust forum..Lots of info over there in the present
and past pages..
K, duh, that makes sense. Now do you have to have a muffler shop make a 3" Y-pipe to connect the headers to run like a single 3" out the back? Cause I dont see ane companies that make one. I know SLP makes one but thats for the stock exhaust manifold.
