how would it do that? you have a gs300, right?

 

L-TUNED very mild noise at cruising and alittle rumble at WOT

 

Any annoying resonances at cruising with the Borla exhaust? I read that the l-tuned can be annoying at cruising - same for the borlas or is it a different animal?

Also - is there a sound clip for the borla on a 400 or 430?
