Quote: Car is pretty heavy. If that weight is accurate and the converter is on 11.40 - 11.50. Tune it up and 11.20 - 11.30 is within range. I think you'd be hard pressed to get 10's out of the combo the way it sits. You don't have much for a converter, gear or traction so you'll be limited. You also didn't say if this will be full exhaust and what size or open headers. In fact if it's through a full exhaust 11.70 is probably going to be the best you can expect.
I am running TTI headers and full 3" exhaust with an H-pipe Ultra Flo mufflers. Do you think that free flowing exhaust would slow me down by 4 tenths?
A 3" exh system with Ultra-Flow mufflers and a H-pipe slow you down 4-tenths ? No way that system will slow you down 4 tenths. If the pipes are mandrel bent I say a tenth at the most and that only because its an H and not an X pipe. Ron
