Yes, its 3-1/2" wide, Catco direct fit, hi flow.
The old cat was broke about 1/8 the way on the exit end, so the element didnt align. Runs better now , slight improvement on the exhaust note too.
Im getting too old for this!
See you at Meeker Days  |

| I supposibly have a "hi flow" that can be bolted in mine. I notice a MAJOR power drop when I bolt it in. |

What did you have in there before? You shouldn't really notice anything. A good cat of proper sizing should only snag 5-7hp and that's not going to be anything but barely noticable if at all in the butt dyno. _________________ A redline a day keeps the carbon away! |

| Long story short, I have a brand new no name direct fit high flow CAT and just recieved a used SLP exhaust system from a guy in Texas that included a Catco CAT. The Catco CAT is alot lighter. But.....I cant see through it. Wounder if they actualy work? If not there is no reason to installl it. |

I'm comparing to an "off road test pipe"  |

i made mine lighter by taking a section of galvenized pipe and a 10 lbs hammer and shake out the bits. and it didn't cost anything. _________________
