I didnt use the SLP mod, I went the redneck route and just removed the back cans all together, also removed the mid-resonators, and replaced the stock H-pipe with a Magnaflow X-Pipe.. I have noticed a slight increase in the butt-dyno on the torque side, wouldnt really say it added any HP, but it sounds great!!
-Good Luck
