Three weeks ago I purchased a 1985 K100 and I have logged about 8 or 900 miles on it, on my long highway trip the baffle and tip on the aftermarket blew out at 90 mph and since it was 3am I didn't stop and pick it up....  ( DUH ) so I ran the highway for 30 more minutes with a streight megaphone pipe wooo hoo, my hearing might never get back to normal.
 The exhaust system is perhaps a Luftmeister or maybe a Mac.... or who knows what, so here's my delima I don't have a tip nor baffle so what do I do?
 Here are the pipe dimensions.

At the 4 into one collector the diameter ( O/D ) is roughly 3 inches or 75mm 
 From the collector to the end of the pipe ( Exit end ) is 24 inches
The Megaphone end is 4 inches in diameter.


 What are my repair options, I have searched baffles and tips and I cant seem to find anything that matches. 

Will post pics tomorrow

i had a luftshister on a bike years ago--it was annoyingly loud even with the baffle and tip in place.  Always backfired on overrun and fuel mileage was in the 30's mpg. 

i found a nice slightly used OEM system, headers and pipe, and put it back stock--wonderful quiet, pulls stronger with linear torque, no more popping and mileage went up to over 50 mpg.  Best unmod ever.

kennybob's right - no aftermarket manufacturer has really beaten the OEM exhaust system except in the noise stakes.

We have a place here in Little Rock (AR) that does high temp coatings so I shaved off the heat shield supports on my OEM exhaust and had it coated.  It looks great.  I've got a spare OEM exhaust (I think I have two actually...), if you're interested in going back to stock send me a message and we can discuss.

Hi Rola... or should I say...HI ROLAND5!! .

If you have 75mm (3in) outlet on the collector you could fit an aftermarket can/silence on the end.

I just picked up a Remus one with 75mm inlet it came off a k100 on a local wantads site. The only bit you'd have to figure is attaching it to the footpeg/mount with a silence P clip or such.

Get one of these from Malcolm in En Zed (New Zealand) and with some luck you can locate the much more common 50mm (2") inlet can from the likes of Delkevic US, Two Bros, Dominator (excellent pipes cheap from Poland) etc. Malcolm may accommodate a request for the upswing of his collector of you need a stock sweep due to use of panniers, for example.


Here's the 330mm long (13") Delkevic I'm using.
