I was just wondering what else the there is to know about testpipes?
I know there illegal are they easy to remove for inspections though. And do they make the car alot louder? my exhaust is pretty loud already. Anything else i should know thanks. I currently have K&N SRI and n1 catback i was thinking of going turbo in summer but is there anyother mods i should get first? Thanks

 

well a testpipe is just a straight pipe, might make it louder, i have a resonator though with mine and sounds good.as far as gains.minimal...

 

It's a pipe with an O2 bung on it. It'll make the car very loud, illegal and smelly since you're removing an active catalytic converter. On an NA car it's pretty much useless unless you like noise.

 

thanks lol u know alot amby
