I had my a/f ratio go high on my third dyno run, probably the same thing happened here.

If you go with an o/r x or long tubes, even with cats, roush axlebacks will be unbearably loud. Sleeper_gt had jba o/r h and slp competition catback, pretty much just straight pipes with two resonators and it was deafening at partial throttle. Mine is pretty loud now with catted long tubes and gt500 axlebacks.

That would make sense.

I think im going to order up the JEGS (heart-throb) cat deletes, and their cat to axle back 3" exhaust system with h-pipe to my gt500's.

Yeah, I am thinking mine might be too loud with an off road X (or LT's) and roush axle backs. That's not gonna stop me though If I have to, I will switch back to the stock axle backs or pick up a pair of the GT500's.

It gets pretty loud when I get on it but normal driving (shifting between 2-3000) it isn't very loud. At least not inside the car. I've never heard the car from outside. I just installed the Roush AB last week, before that I had the SLP muffler delete and with that setup it didn't matter what i did it was LOUD!!! One thing I did notice with the Roush AB is that the drone between 60-65 is almost completely gone.

Welcome to the forums bro! Looking forward to the install this weekend!

I have cat deletes with 3 inch cat back and just outlaw series mufflers and it is straight piped, not that loud unless I mash on it lol. But, could just be tone deaf to it now lol. Windows are always down too!

Sweet. Hopefully we dont run into any problems.... I always seem to though.... Anyway, just ordered up some new tunes from BAMA to include a lope tune after the install.

Sounds damn good if you ask me.
