Mesa

2013 g37x trying to finish up my boltons so i can get tuned already but stuck between these 2 different exhaust i fully understand what i need to do to make the tomei fit and such im mainly asking if anyone on here has either of these and could give me some feedback on them, specifically the tomei since not many have it on the sedan. If anyone that has a tomei has some dyno sheets that'd be really helpful.
