Just had a new muffler put on and BSR PPC upgrade on my 01'c70 hpt :grin: the upgrade made a noticeable difference, don't know if it got me the 300hp like it said it would but i need more time behind the wheel to get some numbers. the muffler w/ tip sounds awesome. very low with a little rasp to it. nothing like the honda tuners with the fat cans. thought about the cat back exhaust but this saved a few hundred :beer:

You have to go the whole route to get the big numbers. cat back, filter, plugs, wire, etc. not just the chip and muffler. if has relieved the back pressure for sure and opened up the breathing for the engine, now take care of the exhaust and don't forget the brakes and suspension, not to mention the transmission and an intercooler upgrade, plus the turbo. when you start the dance you have to finish bro. that's why all the honda guys have such fast cars. volvos can dance if you prep them right.
