wondering if any of you guys have the invidia N1 single, looking to pick one up and wanted some opinions on it. How loud is it in the cab with a test pipe? Does it sound sick? Whats the ground clearance, my cars pretty low and i don't want to catch the canister on anything and rip it off? would y'all recommend it over the q300? Also would y'all recommend running a full system, header, test pipe, etc, I've read that some headers actually hurt the performance of the car? thanks

 

I've heard this exhaust in person. Its pretty loud imo
