Thread: i neeed help deciding on exhaust

nick do you have a word page full of links?

Unless you want the check engine light on all the time, I would not remove the cat. converter. I would suggest either putting on an aftermarket muffler - whatever brand you like - or what I would do is put the shell of the muffer on (fake muffler - all the looks of a muffler, loud as hell).

Here's how I would do it:
Take off exsisting muffler - cut it in half (length/width along the seam)
Pull out all the stuff inside the muffler
Weld the two pieces back together
Weld muffler back in place

Just an idea. Maybe you want something a little quieter.

wow, really guy? if you dont know how to remove the cat without setting an SES light then you dont know how to mod a car.

I'm going to just do borla mufflers. Whenever I get around to ordering them I'll post a vid.

im happy with pacesetters, no cat, stock res/mufflers....loudish when im on it and no drone ..... maybe ill do flowmasters after hearing bluegtp's vid

I've got a high-flow cat with a glasspack resonator and dynomax mufflers all on 3" piping, love the sound and it doesn't get raspy.
As far as those youtube links you posted the 1st gp sounded like **** IMO, and unfortunately its damn near impossible to get a V6 to sound like a mustang GT. We may be able to beat them in a race but damn they sound good.

togs, 3" magnaflow cat, 3" pipe to dual 2.5 ", cherry bomb vortex mufflers - my current set up and I'm finally happy. No rasp or interior drone.

other than that stay away from v-force mufflers, cheap flowmaster copies, and just too friggin loud.

a high flow cat is expensive??? magnaflow on ZZP is like 60 bucks.

you dont know what rasp is? rev your stock exhaust lol

...? If you have nothing done to it and it's not rusted out the stock exhaust is quiet as ****.

4k is still pretty noticeable raspy i think...was for me. (stock)
Mine rasps every once in a while if i rev the piss out of it on a cold start but oh well sounds great for the most part

Way too raspy IMO, but at the same time it does sound good. Idk I can't decide lol, but if you like it, doesn't matter what my opinion is anyway.

a completely stock exhaust that has no leaks is quiet and damn near the best sounding exhaust you can have.

i have pacesetters with no cat, stock cat-back. it gets kinda raspy up top. just sayin

Its hard for a 3800 NOT to sound like complete ass. Oh well I like my setup but just remember you will have to realize that unless you get a cam or headers it wont sound great.

this is the best setup ive ever heard, with blue's coming in at a close second

I'm beyond dissapointed to think my car comes behind that thing...it sounds horrible. The SLP Catback is very raspy. Plus he only revs it to maybe 2K and I can already hear how raspy it is...

i wanna try a whisper resonator and flo pro mufflers zzp's catback sounds pretty nice...
