Boost controller is just through the power fc. Fiberglass bonnet was on the car when i bought the car 5 years ago, probably should have researched that one. Screamer pipe i knew was a risk but sounds great. And i'd say most people on here have over 90db but thats no excuse. I should have researched my mods more thoroughly and will so in the future. But i still think the boost controller thing is stupid.
