Well, i want my rig sounding good. And since i live in the great state of South Carolina i dont have to have a catolatic converter on my ride. So this coming weeking im gonna get up under there and cut the muffler right before the converter and have a straight pipe all the way through. I have a 93 YJ but i was wonderin if anyone had any ideas about this.
 
dont run it straight piped, itll sound like a wet fart. Its going to be hard to get a i6 to sound 'good'. If you got money, the banks header/torque tube and cat back sound pretty darn good. If not, toss in a dynomax or even a flowmaster - you can even get a descent turbo muffler from the auto store. Its not going to rumble like a v8 so dont get your hopes up. Just keep your piping sizes consistent and smooth.
 
well, a guy i know has a jeep cherokee 6 cylinder and his muffler stops right after the catalytic converter and it has a really nice sound. He's also got no engine upgrades at all.
 
i'm confused. you're saying you don't have to run a cat, but then you're making it sound like you're going to keep the cat and just ditch the exhaust from the cat back. then you're saying that you know somebody who cut the muffler just after the cat? you're making it sound like you're cutting the muffler in half or something. the muffler and cat are two different components. also, doesn't your cat have an oxygen sensor in it? you just gonna get rid of that all together?

if you reread my post, I typed "straightpiped sounds like a wet fart", now straight piped to me means no cats or muffler in my book - I guess straightpiped means cats and a muffler to you.
 
I think he meant a straight pipe in place of cat.
I'm pretty sure he can weld in a nipple for the
o2, an still be alright. Buddy of mine runs a
high lift cam in a 6 an you would swear it was
a small block, but he says no mods to engine
so then he's going to have a wet fart.

Well what i meant is i was goin to cut the pipe right before the cat. and then slice a pipe where i cut it all the way back, my friends jeep has the cat because its illegal not to have them in NC.
 
dont forget that you do need some back pres. not a lot, but some,what you are talking about is open header that = not much back pres. and a crapy sound(wet fart).It would be ok if you put a glasspack on it.
 
I ran a Borla header and flowmaster muffler. sound great when i jumped on it, but it was nice and quite otherwise. But like the guy said, an I6 is not gonna sound all that great, no matter what you do.Like I always say, you can't polish a turd.( not saying your Jeep is a turd, but you get the gist)
 
Not to be a jerkoff but it's illegal everywhere to take off a cat. I know a lot of people in SC do it, but it's a federal law. Plus, if you do it, you can't sell it to anyone outside of SC and smog laws are coming anyway (btw - that's how I moved from NC to SC - had an El Camino with no smog equipment - wouldn't pass and I said - f' this, time to go to SC).
