Hi, all. I’ve had my 2008 40K mile G37 Coupe 6MT for over a year and a half and I’m now ready to do a cat-back exhaust. Based on YouTube videos and reading reviews and posts here, my first choice is ArkGrip followed by Invidia Gemini. Now that many of you have had both of these exhaust systems for several years, what are your thoughts on long-term quality (rust through/failures), scraping on speed bumps (my car won’t be lowered) and, of course sound/droning (HWY and local speeds). Oh, and when I do the exhaust I’ll simultaneously do front and rear bars - Hotchkis is my only thought on that. What’s yours? Thanks for any helpful input you can provide.
