i dont know about vibrant products on a Gsedan.
resonator and mufflers has no backpressure and no purrs. i have done it already. sounds like a civic. sorry to say, but i have done it months ago until i switched to agency power.

 

i dunno, i've heard G's w/o mufflers that sounded alright... what was the exact setup you ran?

 

i think that hks will look too big on a sedan even in person is big lol..i just order my carbon fiber muffler..so i hope everything will work fine for me when i make it a nice look ill make a video for sure before and after
