Berk CBE Help

BrandonT · 06-12-2011, 09:12 PM

Just installed the exhaust. I trimmed the passenger side tip about 3/4", and made the slit longer:

Nothing a Dremel tool with cutting wheel and grinding stone couldn't handle. Pushed it pretty far back, it ended up about 1/8" behind flush. It helps to grind the inside weld so it slides easier, even then I had to use a mallet and rod and tap it back and forth to move it back.

Now this is cold, it was about a 1/2" farther out when it was warm. So I'm not sure if I'll leave it there or push it back some more. I was starting to get to the curve of the pipe, so not sure how much more I could go without the tip getting cockeyed.

Regarding fitment, this is my first exhaust install so I don't know what a normal tolerance is. But I thought it was mediocre. Flanges were somewhat off and one flex joint was tilted, although its flange aligned ok. The tips were not level and I had to lower the passenger side 1/4" to get them to look good. Overall not a big deal, everything was tweakable for even a novice.

The sound is glorious

Nice job! This was my first exhaust install too.

My driver side flex pipe was welded on a little crooked too but I was able to snug it down and it seems ok.

My passenger side tip sat higher also. I just lowered it with washers to make them even at first. Eventually I decided I wanted both tips sitting higher inside the cutouts in the bumper but was too scared to bend the hangers on the exhaust itself so.. supporting the exhaust with a jack stand, I took the driver side bracket off and bent it up instead (I picked up a spare one at Courtesy just in case I effed it up too much

). These are very easy to replace and you don't have to jack the Z up to do it.

I actually just put the thing in a vice and tightened it down until I thought the bend at the end of the bracket had straightened out enough to raise the exhaust. It could still be higher but I'm done messing with this thing for now!
