Does a High Flow Cat increase sound?

[silicuda]

I have flowmaster 80 series exhaust on my 3.4L and they are awesome. Sound sweet on idle, and NOT ricey on high rpms like 3.8L's.. anyways...

I am wondering if I add a high-flow cat, what will that do to the sound of my exhaust?

louder for sure, depending on how big u get, and maybe mroe high pitched at high rpm's.

The 3.4 60* naturally sounds better than the 3.8 90*.

I've heard that headers and some kind of CAI would deepen the sound while the highflow cat makes it louder.

Just gut you cat. ;)

That's what I've been told several times. So it must be true [img]smile.gif[/img] The only aftermarket exhausts I hear around here are Mustangs and trucks and 4 bangers. EVERY SINGLE camaro driving by in town has been stock...That I've seen.

WHen I get my catback, I'll be break ground ;)

Yeah, a high-flow cat is gonna make the sound more deep and throaty, not to mention add more HP.

If you're gonna go and install a cat, look around for some pacesetter header too.

I agree. It's just like the LT1 sounds better than the LS1. But we know which one outperforms the other! [img]tongue.gif[/img]

Fear Factor...You have those fuggin emission inspections huh? Yea I hate them too, that's why I got my car registered in Alabama rather than MO, any tips on how to gut the cat, all would be helpful..any drawbacks? Anyone???

Same here. I got my car registered in Illinois. Missouri has crappy laws. [img]graemlins/thumbsdown.gif[/img]

Christian: gutting the cat is easy, although i cannot do it.... u take off the cat, get a rubber hamber, bang the walls up a bit, then u get some long metal rod and u put it in the opening and u hammer away the internals... after everything is done, u get a straight pipe.. pipe it through and weld it in place [img]smile.gif[/img]
