bolting on 2.5" to 2.25"???
ALMOST DONE! I'm having another slight problem, has anyone tried to bolt a 2.5" h-pipe to a 2.25" (stock) cat back? The holes in the flanges or whatever they are called, from the cat back aren't big enough and are not allowing the studs from the new h-pipe to go in. I thought that I was going to have this problem. I can always make the holes bigger on the cat back flange to fit the bigger h-pipe flanges. Is this what I'm going to need to do until I can afford a 2.5" cat back? OR if I wanted to be REALLY loud I could just say screw it all and do dumps

Tim, that's what I'm going to end up doing tomorrow, I'm going to punch it and drill it out and use a burr on the dye grinder to touch it up. Negadivone, all I've got to say is you are one lucky bastard lol.

I put on a 2.5" o/r H pipe and it bolted up just fine to the stock 2.25" cat back. just took a little bit to get the bolts through the flange.

Alright guys, the exhaust is all done and I test drove it. There is a performance difference! The sound is awesome. Next on my list is underdrives... $64.00 a good deal for underdrive pullies? Anyways, I've got to go to the hospital, I got a metal shaving in my eye and it's scratching the hell out of it, thanks all!

i just hooked my mac xpipe up to my stock pipe/muffler/etc last week, and i just had trouble with the driver's side flange matching up with the studs from the xpipe. i ended up starting the bolt on one side, and beating the flange on with a hammer while i pryed the stud up into the hole. many times brute force saves money
