Berk CBE Help

BrandonT · 06-09-2011, 12:55 PM

So I just received my Berk exhaust and took a look. It looks like only the tips need to be trimmed. The tip can be slid about as far onto the pipe as you want, it's tight, but you could it. So I'm not really sure the pipe needs to be shortened? Not really sure what that would gain except not having it protrude into the tip? You can't really see it. OTOH the tip has the least tolerance to trimming. I would imagine you would want to leave some of the slits so the clamp can squeeze. But the slits are only 1" deep so I wouldn't be comfortable taking more than 1/2" off. You could make deeper slits but that is lot more work for the DIY'er and might get you another 1/2" at most.

I may have to get everything hung before I know how this will work out...

I don't think people were saying the pipe itself needed to be shortened but, the collar on the passenger side tip itself needs to lose about 3/4 inch. In my case I also cut those slits a bit longer to make up for the lost material on the collar.

If you simply jam the passenger side tip forward, the bend in the pipe causes the tip to angle to the right which looks unsightly.

Hopefully I'll have time tonight to get a couple pics of what I'm talking about.

I'm sure the adjustable tips are a tiny bit heavier with the clamps and the extra length of tubing involved but its minimal.

That's what I figured.

Gotchu99 mentioned having the pipes cut at a muffler shop which confused me once I got to looking at them. He must have meant the tips. I'm going to cut the slots up to the weld on the problem side and take maybe 1" off the collar. Probably drill a hole where I want to end though so no stress cracks can start.

Drilling holes for the slits isn't a bad idea.
Heres my passenger side pipe after all the work:

I left enough of the collar so the clamp would fit without overlapping the weld or hanging off the edge of the cut collar.

Its been like this for about 2k miles now and hasn't changed its position. As you noted, after cutting this much off the collar it is essential that you elongate the slits so the clamp can still do its job. Good luck!

Mandingo, that looks like a nice fit. Good job. Have a free rep point on me.
