So I'm considering an upgrade to 2.5" cat back exhaust + 3" down pipe and I could use some guidance from those who own one. However... I have the ragtop with the associated rear chassis brace PLUS I have the Curt trailer hitch installed. Just to make things complicated enough. I also want as little noise as possible. I'm not looking to replace the exhaust for sound reasons but to get as much heat out of the engine as possible as fast as possible. There are 3" exhausts which would be more suitable but I'm sure they won't clear the chassis brace. They'd also be way too noisy.
I like the concept of the ARK GRiP exhaust "J Pipe" for passive noise cancelling but the hitch is in the way. It may be in the way for any of the aftermarket mufflers but I don't think so. The stock mufflers fit just fine, but only just.
The COBB system is interesting because it has a 10" resonator just after the down pipe. None of the other systems I've seen have the resonator. But the COBB system uses flange connectors just behind the rear axle, right where the chassis brace has to go. So I'm not sure if the COBB flanges will clear.
The Hooker system might also minimize the noise from the free-er flowing exhaust but it's hard to tell from the videos.
I don't care how noisy it is outside the car, only how noisy it is INSIDE the car (what some of the manufacturer's call "drone"). I've had my fill of noisy low restriction exhaust over the years. I want peace and quiet. I wish there was an electronic noise cancelling system but I haven't seen one yet. Nor do I want to pay for one.
So I guess I'm looking for the quietest 2.5" cat back system. Quietest inside the car.
Opinions from those running the various 2.5" systems welcome.
Thanks.
