On stock exhaust?

LEAVE IT

WOW!!! AGREED! lol

_________________

Yeah on stock exhaust leave it on. I had no resonator on my old GTP, stock exhaust otherwise, and it sounded like ass. My GTX however has a 3" catless DP, no resonator, 3" pipe back to 2.5" Dynomax mufflers and it sounds pretty good. No rasp whatsoever, but the resonance does get kind of annoying at certain speeds.

just cut it out if you want to. its louder and a little raspy but who cares. put a glasspack in place of it if you want, it'll sound way meaner and wont be raspy.

i got flow master 40's and still have my cat on but removed resonator. i get lots of compliments from people on how my car sounds. I love the sound it makes personally. but keep in mind i still have my cat

I don't have a resonator on a mostly stock (stock sized, anyway - I haven't done work on it) exhaust, and it doesn't sound too bad. Sure it's got a little rasp, but nothing unbearable. Does wonders for fuel mileage not having that restriction in there though.

you wont notice any performance losses or gains, you'll pick up soem gas milage, and the glasspack will make it sound super mean.

I actually added a 2' resonator to my SLP Loudmouth exhaust and couldn't be happier with the sound.

At 70 MPH it's nice and quiet now instead of the headache drone.

Let's put it this way, with my tune I can hit 34-35 mpg highway running 70-75, a bit more running 65.

I like the sound of my resonator-less mostly stock exhaust w/ summit fully welded mufflers. Gets droney at cruising, but whatever. Unfortunately, it also constitutes probable cause for a traffic stop in Iowa. Bastards...

People in Iowa stop anyways...slow slow boring state...no offense to anyone who grew up here...1 summer at a time is about all I can take.
