Anyone tried the TTI shorty headers?

No doubt you will get some to respond that the long tube headers are better for performance (which they are to a degree) but if you spend any time really researching and understanding the subject you will find that long tube headers really come into their own at differing RPM levels than shorties; normally their max benefit is at higher RPMs. For a driver or street car you will most likely never know the difference unless you really pound on the car a lot frequently. I would not hesitate to run them.
