Fast Intentions Long Tube Headers are here!

Sadly, I think you really have to do this in order to clear your name. People believe what they read and right now there is a lot being written that LTH's will not work with a supercharger even though Tony said they would. Nevermind the fact that superchargers have worked better with less restrictive exhausts for the past century, now things have magically changed for the VQ37VHR. I think that getting your hands on a well tuned supercharged 3.7L and doing a back to back study of restrictive vs unrestrictive exhaust would force the others to answer some questions. I would leave the cat-back the same in order to eliminate variables and tune each combo for their best performance. And it looks like you would have to use a Stillen kit as it looks like this is the only supercharger that is out right now that can push enough air.

To be honest with everyone else, I have no intention of buying LTH's. I have a set of hfc's and a set of Stillen headers in the basement that I believe would work real well for me. I got both the headers and the hfc's used and cheap. My reason for posting is because someone is putting out bad information about a supercharger needing backpressure in order to run efficiently. That is simply not true.
