4 cylinder exhaust ideas?

[19bonestock88]

so when i finally get this backfire fixed, i plan to redo the exhaust to eliminate the rattle caused by the backfire loosening the insides of the factory muffler... i'm hoping to maybe gain a little over what i have now, which is the stock manifold, a hollowed cat(i didn't do it), and 2.25 inch pipe from the cat to the OEM muffler, and the 2.25 inch goes to a side exit setup with a 2.5 inch tip... thought about going to a j/y to pick up a manifold from a 97-ish 2.3(cheap shorty header) and run a 2.25 from there through the cat(straight pipe through the center of the cat so people think it's still there) to a muffler(don't know what kind) and a side exit setup with a nicer tip...

should i expect any gain at all?
what muffler should i use?

all ideas are welcome...

a hollowed cat(i didn't do it)

Sure, I believe you. Somebody keeps hollowing out all my cats too.

I had a flowmaster 44 on mine, also with no cat, and it sounded pretty good to me. At the moment I have a Walker made for an 06 V6 Dodge Magnum, or something like that. I put it on to keep the noise down while I was tuning a new carburetor. The flowmaster is going back on when I get around to it. The junkyard shorty header is a good move judging by what I have read. I have a Hedman long tube myself.

yeah, i hope for the system to be somewhat detachable so when the build reached stage two(or maybe it was three) the exhaust can be redone again reusing some components...
or i might just use cheap mild steel for now and upgrade to SS at the higher build stage(either two or three)... either way, the rattle is driving me insane. sounds horrible at idle and those loose insides can't be helping performance...

I put slots in the mufflers I use and use T-bolt clamps. I have had good luck getting things apart and back together. The flowmaster was actually a take off from my Mustang.

interesting... how's durability from the clamps? i've always been told the only way to go is welded...

old thread but i agree on the super 44s. i had basically the same set up youre thinking about on my 95 but w/ 2.5 in piping. sounded great for a 4 cyl. not ricey at all it was a low(ish) mellow tone

Put one collector on the 4 pipes and dump it out the side right after the front tire. Boom, now what do we have? A sweet rally truck exhaust, that's what we have
