Im about to go with some Pace Setter long tubes, x pipe, and 2.5'' true duals here in the next week or so. I have everything ordered just waiting for it all to come in. With my cam and me having shorty headers and 3'' catback, what kinda gains can I expect going with long tubes and true duals OVER what I have now? Some say long tubes and duals in a cam'd car will usually make about 15hp over shorties and 3'' catback. Any comments?

 

I remember last time, I was at a dyno day I saw 2 LT1's both with a hotcam. One car with shorties pulled 310rwhp, the other with long tube pulled 335rwhp.

Thats a nice difference. I have a slightly bigger cam than the hotcam too. I know every car is different though. Just depends on your setup.

 

Any other comments on this?
