You don't need to setttle for the finish provided by the manufacturer. I should have mentioned that a better way to re-contour the covers is with an exhaust pipe expander. I didn't have one large enough but I may pick one up and redo it. Harbor Freight has an inexpensive one that should do fine:

Great 2nd post!

MadMan77 · 12-09-2008, 04:22 PM

Very nice indeed.

lowflyinrabbit · 12-09-2008, 07:58 PM

Nicely done! :w00t:

m7ammed · 12-10-2008, 12:13 AM

so if I understand this correctly you shaved a bit of the performance exhaust tips?

Gogud · 12-10-2008, 12:24 PM

Huh? The overall length at the maximum extension point (the point where it sticks out furthest) is still the same as stock and was not cut back. Only enough material was removed to match the contour of the tip covers. I can see where my use of the term "re-contour" in the above post may have been misleading. You have to cut to re-contour. The tail pipe expander can be used to bend the lip outward to lay flatter against the part it covers. You do this after the tips have been cut and the covers installed. This should make it easier to do a sano job plus it can be done on the car.

I did this yesterday and it was super easy. I didn't even cut off any metal. Basically, I pulled off the black tips , flatened 3 of the 4 spring\retaining clips, lined them both up and went to town with a rubber mallet! This is the look that I wanted. They look great and they definitely do NOT stick out too far.

As I've posted before the sound is awesome!

EDIT*** I stand corrected. I cut 1" off of both tips and the end result looks much better.

tkbr0wn · 04-04-2009, 09:39 PM

Just did it.... Piece of cake.

It's dirty and just a phone picture, but you get the idea:

I have the stock exhaust, but hey, couldn't this be a simple way of getting a larger exhaust tip?
I think a 1/2" expansion in diameter would look good...maybe even more.

No pics. The interior of the stainless tips on the Performance Exhaust turn black, just like the interior of the original aluminum tips. The black exhaust tips are merely "finishers" that slide over the original as well as the Performance Exhaust tips.

Thanks, 2nd question. In the old days when putting chrome tips on my E21 323i, or on the 325i E 30, the tip would slide over the pipe and there was a screw you tightened down to hold the tip on to the inner pipe. Do the black tips need this or are they tight enough. (or even too tight so they cannot be removed if wanted or needed, e.g if rust builds up)

I would suggest that you go to the rear of your 135i after the exhaust has cooled down and pull off one of the shadowline tips. That's all you have to do, just pull. Then you can take a picture and post it. You'll see no screws, this is BMW OEM not Pep Boys chrome tips.

They're pretty tight. I had to bang them on with a rubber mallet, but if I really wanted to (with a little elbow grease and a lot of profanity) I can remove them.

Don't over think this--just do it if you want BMW shadowline tips on the performance exhaust.
