And I have to completly disagree with the above statements. My THS pipe has improved performance no matter what engine I put in my revo. It just made everything come to life. Slightly lowered temps compared to stock (5-10 degree's), gave lots of low end power without sacrificing the top end. Great mid range. Heck ask anybody that saw my revo in its prime and just how my 3.3 just had gobs of power and never seemed to run out. Id recommend getting a new THS pipe if you feel yours is worn out.
