Has anyone ever ran a bumper exit all motor? Like a 1320 one. I’ve had nothing but issues with my exhaust had a whole exhaust put on and it’s always leaked at the header and i’m low so i scraped the flange off from my test pipe to the catback. I know it’ll be loud but i could bear with it since i’ve always had an exhaust leak, it’ll be put on a ek with a b16 built head and soon to be put in pro1 or maybe pro 2 cams. Just wondering how bad the noise is inside the cabin, but i kinda figure it can’t be that bad since the exhaust isn’t right under me?

 

Yes its very loud.. and does get very annoying. Also you can get pulled over for it depending on where you live. To help with a bumper exit.. install a resonator before you exit out.

Also if thi king of using pro2 cams you need min 13:1 comp for them to make you any power and gains. Also they are not drop in cams.. thry need to be degreed in properly so you will bend a valve or worse.
