this is why TTi headers suck for power

And when the car that engine is going in clicks of a 9.80 or so??? And it will!

Compared to the other headers run on different dynos with the same results, the TTi's were not the best performing. Not even close. If you drive your car on the street you have other consideration to ponder.

Street car... Dougs or tti's, gotta be careful with hedmans or hooker SC.

Race car... tti won't be anywhere close to my car.

Be fun to watch what the car that had the tti's on it runs when a different header is installed. We figure at least .10-.15 and maybe .20
