RPI GT Exhaust

ArthurL · 05-21-2015, 03:25 PM

I currently have an RPI GT axle-back exhaust.. and I'm considering test-pipes. Is anyone currently running this axle-back exhaust with test-pipes? How is the sound? Is there rasp and/or drone?

I am not running a axle back yet, but I do have test pipes with a tune and the sound that it makes just with the test pipes is too me amazing. Big difference over stock. Zero drone and little rasp.
