alright guys i got a few question regarding exhausr and so forth. i have a 06 ss/sc w/ fujita intake, and stage2. i wanna get a downpipe and exhaust i was thinking of 2.5" catless DP w/ a 2.5 inxh catback i was searching around and came across a MEGAN RACING compete 304 stainless exhaust in either 2.5 or 3.0". any other options you all would consider? thanks

 

i have heard evey one saying that unless you are making like 300 hp the 3.0 inch isint going to do much for you. that 2.5 is ideal. i would like to know more also im in the same boat as you

 

Bro with those mods I suggest a 2.5" DP with a high flow cat.

Catless is a little raspy and 3" is too much for those mods. Just my opinion.

Not to mention no CEL when you have a cat.

Running catless would give you about a 1-2hp gain. Not worth it.

 

The car gets alot louder w/ out a cat just to let you know

 

awesoem advice thus far any recomandations for DP? cobalt addiction etc?
