Exhaust Opinions
Just curious what everyone is running for exhaust and/or their opinion on what is best for 4th gens. I'm currently running straight pipes and LOVE it but I'm thinking about switching to loud mouth.
How about you guys?

could you be more specific with the straight pipes? longtubes into a true dual system w/no mufflers?
I used to run longtubes into an ORX w/dynomax bullets dumped before the axle and it sounded great

stock except for the muffler till I get back. ls1addict actually showed me the xpipe which I will get with some long tubes. Some high flow magna flow cats and some flow master single inlet exhaust is the plan. probably going to have them come over the rear axles and out the back dont like the idea of dumping them before the axles.

Long tubes with true duals with x-pipe and two Borla XR1 mufflers. Exhaust extends to the rear bumper, not dumped. Sans cats.

Running Pacesetter long tubes, into 3" Texas Speed catted Y, into Borla with open plate.
Love the sound. I had an off road Y, to me it sounded like poop. The high flow cats clean the sound up a little, and still flow good. I personally don't like the sound of no cats on a Y pipe. Just sounds loud and "un-tuned". Not bad on true duals though.

Keep the Flowmaster and put in a cutout. Keeps the Flowmaster sound and lets you get the power when you decide to use it. IMO
I have pacesetter lontubes & Y with Magnaflow cats, 3"cutout to a Flowmaster 40 single in/dual out. Love the Flowmaster sound
