Very cool i have a 2.5" in/out super turbo sittin in the garage (Not sure on the model #)!! I'm not very familiar with the 99 Trooper but on my Rodeo I have two cats then a "Y" pipe to my muffler... Does your trooper have the same?? If so did you have a shop build you a less restricitve "Y"? Thanks for your input <img src="/forums/images/graemlins/cheers.gif" alt="" />
