If I have a 4-to-1 Kerker, can I change the tip?

It seems like I would be able to change the Kerker 4-to-1 muffler tip to one of the newer style muffler cans the we see on newer street bikes. Are these muffler cans universal? I would think so. I just do not like the sound that I get out of the Kerker, so lame. The bike (83GS1100e) is so powerful but it sounds weak. Any thoughts? Suggestions for getting some more sound out of it?

Thanks,
Pat
 
Since the can does come off the pipe your possibilities are endless.
Talk to posplayr and he may be able to get you on the right track.
 
Be aware, the CAN itself is not the only source of "tone" from an exhaust system. The can simply acts as a resonation chamber. The baffle design, design of the header and midpipes also come into play on the "sound" of your exhaust. Frankly, on a big 1100E motor, the VH and Kerker canister exhausts ALWAYS sound wussy IMO. You need something with a bigger diameter mid and head set. Thats where the baritone will come from. That and how much/little baffle and packing youve installed...

most all of the modern slip on's are 2 1/4" tubing (inlet)

The older yoshi canister style are all 2 1/2" tubing (inlet)

You can find adapters to make a mid pipe, even out of stainless. So depends on what size inlet your can has and what collector size is on the header.
 
how about pulling the stuffing out of the can?

how about pulling the stuffing out of the can?

I appreciate the input. One guy said that it depends on the amount of stuffing inside. What happens if I pull a bunch of that stuff out? That might step it up a few noches huh? I might try it, although I really am not sure what is going to happen when I do. Does anyone have experience with this?

Thanks,

Pat

And may also require some jetting adjustments...minor, but still...

The removal of baffle packing will allow for more airflow, which means a slight bit less back pressure... Tuning carbs for pipes and pods is a bit of science, a bit of luck, and a crap load of trial and error and patience if you want it perfect. And even then, depending on the set up, there are likely to be "flat" spots in the rev range, albeit small. Or, depending on the pipe design, you may lose a bit of your bottom end "grunt".

That pipe you have now is a good "street" design pipe. While the tone kinda sucks, the pipes are somewhat small, keeping the midrange power in line with the stock set up. A larger diameter pipe will lack some of the midrange grunt, but make up for it in a retrorocket like top end rush that will have you seeing the orthopedist for sore shoulder and elbow joints ;)

Sounds like a nightmare :D
 
you can make any exhaust you'd like fit, just visit an exhaust shop and for like $10 or so, they'll bend and expand the ends of a piece of tubing to make a nice clean midpipe to join header and muffler together.

I did this for my XT600 when I picked up a shorty exhaust, the tone wasnt much louder than stock, but it did change just a touch, and gave me a more free flowing exhaust.

its all about how you like it. my friends dad has a full supertrapp on his GPz1100 and GS1150 dragbikes. the 1150 sounds really really beautiful with this pipe, although I dont care for its style.

and exhaust inlets are NOT all the same size. some are larger, others much smaller. the 98-03 R1 has something like a 2.5" ID on the pipe, while the YZF600R, has a much smaller 2" or so.
 
Thanks for the input, now I have another quesiton

Thanks for the input, now I have another quesiton

Has anyone here ever done an undertail exhaust on a GS1100E? I know an exhaust guy that I am sure could make it happen, but I am curious to see if that might cause any trouble with anything else on the bike. Any input is helpful and appreciated.

Thanks,
 
I'm unsure if that would possibly generate a significant deal of heat on the area between your legs, and possibly a few other unpleasant ones. the muffler may cause interference with the rear wheel at full compression of the shock.
