65hp from welding your 5/6th ports open and a straight exhaust...
Was this exhaust manifold back, or what. |
that's just my guess
|
and from the manifold back, no cats or muffler
|
We are going to try to put my stock exhaust back on and dyno it than put the one we made up on to see what diffrance it made on a dyno
|
I don't think we could patent pipe, that would be like trying to patent watter.
|
dyno results would be nice.

question... does wirig open the ports actually increase horsepower? i mean they open at 3800 anyway.... whats the difference... arent you just losing low end?

i can say for certain that it is nowhere near 65 hp (over stock). the most rwhp i have seen out of a stock NA block is 200, and that was with everything tuned, not just a straight pipe. but i am sure it is a significant gain with jsut the straight pipe. it is amazing how much the cats can change the performance characteristics of an engine
