right now i have comptech exhaust at 60mm (2.25 i think) and i like the way it sounds, not too loud but still enough tone. i want to make a solid 300 whp with a little room to go higher in the future, but want to keep the exhaust. will this be a problem, if so, whats a good brand-pricewise and reliabiliy. i dont want to attract too much attention but i also want the power. also what about the cat. i would like to keep it, but then which one should i get? thanks for all the help guys!

 

thats tiny *** piping, i made 306 in a 3 inch exhaust, help "breathe"better

 

if you were able to make 300whp on 2.25" piping and one day decided to upgrade to 3", you would probably pick up 50whp.....upgrade to 3" or 2.5" at very least...
