for everyone running a full exhaust what kind of hp and tq did you see after the install of aftermarket header, dp, catback.... just wondering guys.

should it be close to around 20 hp and 15 tq or should it be more?

 

10 to 15whp on a highly boosted car. 2.5"

 

should be more than 10whp... i would say closer to 20 for a full exhaust... never know though till you get that beotch on the dyno

 

I will let you know in about 1 month. I go on the dyno for tuning mid April.

I dyno'd 242whp/212wtq with just stage 2 and the CAI.
I have since installed a full exhaust so I will have pretty accurate numbers for you.

 

thank you

yeah i dnyo 247hp and 231 with the 2.8 and gm stg2 yours should be in the ball range mine is in please let me know when you get dynoed
