My civic has a small 1300 engine and doesn't have much power I looked into getting a cat back system but they only run for 88s and up which is lame but I was thinking bout gettinga Gibson superflow CFT muffler I think is what it's called? I was just wondering if that would add more HP and if it would be a good idea and inExpensive. help me out please thanks!

 

Skunk2 70mm full exhaust will not let udown
itll raise u from 290hp to about 305..
with just the exhaust system it self ..
sounds amazing and proformace is great
allthough its prob a penny cheaperif any at all its worth every bit..
good luck and either way u will be happy bro.. let us know what you get

 

I was also wondering if I needed a muffler? Cause mine goes from the cat and then muffler then tail pipe but this skunk2 just goes from the cat to the tail pipe? Could you educate me alittle? I just want my car to run better and have more power lol
