resonator?

[MikeGTP88]

well i have been wanting to do something to my exhaust for a while not and was thing about the high flow cat and removing the resonator? howdo you guys think think this will sound?

if u still plan to retain your stock mufflers it will sound decent. i have a hi-flo magno-flo cat and a 2.5" catback to the stock mufflers. removing the resonator will cause the exhaust tone to be a little raspier but, again, if u plan on keeping your stock mufflers it wont sound too bad.

[MikeGTP88]

yes i plan on keeping the stock mufflers.

I wish I had kept my stock catback. I did have my resonator removed on my stock catback and it sounded ok for a V6...the quieter the better.IMO

I gutted my cat, and kept the stock resonator, and changed the mufflers to some dual chamber flow masters.

A stock resonator will keep the rasp down, while giving the car some great sounding attitude through out the whole RPM range. Not just at idle.

Really? I've not heard a good sounding V6 yet. But then again, my first car with headers and full exhaust was a 72 Chevelle 350. I suppose what sounds good is relative.
At Branson I most liked the sound of Reptiles car at idle and Trannymans Cutlass.

Can the stock resonator be put on a 2.5" catback w/o causing restriction? My GMPP resonator took a dump. Meineke put another resonator in it's place, which I thought made little difference in sound. However the restriction was so great no matter the pulley, I was getting 6* of knock. Remove the resonator and removed the knock. Thanks to Dave for finding this.

I had my resonator removed I think it sounds alot better, mine doesn't make any rasp noise that is talked about. I was worries when I did mine that it would sound like crap and it doesn't least to me.

thanks for all the replys one other question..i was looking at a few different downpipes and high flow cats. i was looking at a zzp one and random tec one. i also talked to someone at an exhaust shop and he said something about the high flow cat may trip the ses light..anyone have this problem.

there have been a few incidents with older designed dp's tripping the SES light, but there are at least 3 fixes for this:

1. get a spark plug anti-foul bushing (right thread count/pitch is vital here), screw that into the o2 bung, annd put the o2 in the bushing.

2. leave the o2 as is, and use a powertuner/similar to delete the code from the PCM

3. get an o2 simulator, and block off the pipe's o2 bung (or if you want to be stealthy, hide the o2 sim, and leave the stock sensor in place, route wire as to not show that it's not connected.-- for visual inspection)
