Which exhaust??

[Sny]

fifteen minutes tops! toughest part was getting the spring back on, but once i had the right tool it only took 30 seconds! hope yours doesn't require any 02 mod or juice box. i'm on the border as to what i'm going to do. mine is backfiring with the hindle.

Get yourself some fuel. I still recommend a power commander as their O2 Optimizer is a lot like the O2 modifier we can't get anymore.
Regardless, it's one of the best improvements I've made. I was pretty close to thinking I need to sell it because of how poorly they run without. Adding the pc5 even without any map changes made such a world of difference. Backfiring, gone. Smooth, no more surging, great feeling at lower rpms. Just sounds like a much happier engine. I won't try and explain it, but it sounds like it's better lubricated with a richer mixture.

I had a stock exhaust on after my hindle temporarily while I ordered a replacement, went with a Yoshi R77, love it, best of both worlds. Sounds and looks better than stock, not as harsh sounding as a hindle. Even with the stock exhaust it runs like a different engine with the PC5, and I attribute that almost completely to the O2 Optimizer/modifier as opposed to the open fuel map.
