Exhausts

[mcollect]

The handguards are from an 1150GS with the Touratech spoilers attached. They took a bit of language to get on properly but they are great. Too good sometimes, for Tucson summers, as they keep all the airflow off my gloves and my hands overheat.

I keep mine on year round, I am extremely allergic to bee stings or other bugs up my sleeves. Since putting them on NO stings= NO epinephrine.

I had a Staintune Y-pipe installed... and I removed it because of the occasional backfire. it really bugged me.

went back to the stock cat, and no backfires (i know that the backfires are still there, just muffled by the cat). at this point I also swapped out the Staintune end-can and ended up putting a Zach end-can on. the Zach sounds bass-ier than the Staintune can and looks more stock.

and any performance improvements are all in my head.

here is a pic of the Zach end-can.

Thats a logical train of thought. I can't take mine off without going back to the stock bar end weights, because the throttlemiester is for a GS with handguards....not sure how well it'd work without the guards, other than just as a heavier weight.

And I like the backfiring from my exhaust cuz its a low-pitched pop, more of a booming sound than anything else.

I also have a black R1150R and know the Buxton area well. I've worked there since 1975. Never been tempted to throw the standard exhaust away and fit an expensive replacement. If you want some nice airbox noise get the revs up to 5000 or so.
Seriously, I get so much wind noise with my BMW helmet I'd probably not hear the exhaust. Mine goes just fine and I like the looks of the standard system.

I weighed the cat and muffler a few months back.

Muffler = 5.6kgs (12.3lbs)
Cat (with stuffings) = 6.9kgs (15.2lbs)

Does anyone know the weight of the Y-piece and the average weight of an aftermarket muffler?

It would be nice to compare the following options:
- stock (cat and oem muffler) ==> 6.9 + 5.6 = 12.5 kgs
- cat only ==> 6.9 kgs
- Y-piece with oem muffler ==> ??? + 5.6 = ???
- Y-piece with aftermarket muffler ==> ??? + ??? = ???

Arjen,

The total weight is 13.0kgs actually. Your calculation is correct but the ornamental cover between the CAT and the muffler weight at 500g

Okay, so its not really related to the OP, but I thought this was worth a good chuckle.

I went on a ride with a bunch of sport bikers. The local yamahondazuki crowd and one was looking at my bike and the "weird front end" and said "Those header pipe's look nice, what kind of coating is that?"

I looked at him, a bit bewildered before smiling and replying: "Nothing, thats just time and mileage."

I guess they nice, and oddly even blue-ing of the pipes looks good (and after looking at it every so often, I like it) and that completely removed any thoughts in my head about coating my pipes.

Yay for chromed/stainless steel header pipes.
