The WSP & Cattman pipes like VERY similar - besides the material. I tested the WSP pipe and found a loss on the dyno. Has anyone dyno'd the cattman to prove anything?

If anyone can prove a gain, where is the difference???

 

i think the only dyno available right now is the one that cattman provided.... haven't seen any third party dynos yet....
i said in my other post that i will try to get a track time (plannign to go next friday).... i'll let u kno how that turns out....too broke for dyno =)

 

everyone with the Cattman pipe has claimed a butt dyno increase, but thats it, no dynos

 

my dyno results for the WSP y pipe were positive. 224whp and 236tq for an auto is pretty high. I've gained approx 34whp from GAB, WSP y, catback, and UDP. It also held 200whp all the way until redline 6600rpms
