more power

Hello, I was reading the forums a month ago and I saw where one of you recommended to take the sleeve out of the fender for more air. I have a knn filter, do you guys mean the short sleeve between the airbox and fender? I have a '95 with a cummins of course. I had just purchased the truck 1 1/2 months ago, it looks like it has a catyletic converter on it. Is it lagal to take off on a diesel truck? I'm also looking for a set of factory late '00-'02 8" aluminum wheels at a really resonable price. I like the looks of them better than my 6.5 chromes.

Thats the one. You can drill some holes in the bottom part of the airbox for more flow too.

It's against federal emissions regulations to remove the cat on a gasser or diesel.

Aside from that, it sounds better, EGT's run cooler, and some guys noticed slightly quicker turbo spoolup when running catless. But legally we cant recommend removing it.

If your worried about it, cut it open and remove the insides then weld it shut and put it back on. Same for the muffler if you live in one of those noise restricted neighborhoods. Just my thoughts on that.

Unless you be stupid and try to disturb the piece then i don't no why u would get pulled over. I bought my truck in blair,NE(woodhouse) and it was straight piped, and sold my 89 cummins with a straight pipe.

If you're looking for more air flow, ditch the K&N, and go with a BHAF. Chunk the cat and muffler. While you're doing the BHAF, chunk the silencer ring too.

What does BHAF stand for and does it mount on tube going to turbo and chuck the box? Also what and where is the silencer ring ? Sorry about the questions but I'm new to the diesel scene.
