How much power?

[Jayrock39]

I just added an Injen Intake and Stainless High Flow Muffler. My question is how much HP do you think that added and how much more can I get from a header and cat or test pipe? This is on a 93 Laser RS with the 2.0 NT 4G63.

Just a muffler and not a cat-back will only get you 2-3 HP becasue you still have a hug bottle neck till the muffler. for the most power you need a header,test-pipe,and cat-back.

exactly how does a test pipe work on a NT dsm... i know on some honda applications you end up losing hp..

never thought about it on a nt dsm
