Hey guys, i just recently went to a meet and i was told that i can run Cobb Stage 2 with my factory DP....Is this true...I have a COBB catback that has replaced my midpipe cat and i have stock DP/UP but he said that i can run Stage 2 as long as i have only 2 cats.....Can you guys help me with this....i do not wanna hurt my engine ....thanks

nooo, you still have alot of back pressure with the stock dp, you could run stage 2 with a downpipe and stock everything else, but i wouldnt run it with a catback

go back to that meet and smack someone in teh head. Keith has it right.

u need a downpipe to run stage 2

thanks that is what i thought ....cause that is the first that i had ever heard of that and i just wanted to confirm it with you guys..Thanks alot

Yea, i didnt think it was gonna be a good idea to run it w/o a new DP.

you definitely need a downpipe though! :D :banana:

Are you sure they didn't tell you stock up-pipe?

Do it and trade your car within a year to get another one ;)
