Hi guys,

Great board you have here, glad to have found it!

My 500R is the only non-fuel injected thing I have ever owned, so forgive me if this is a silly question, but I was wondering if there was any way to change the dual exhaust to a single larger one off the right side like teh ZX-R's have. I think I saw something a while back, like a DIY - and I'll try and remember where it was. But, in the meantime, any of you guys heard of/done this?

Thanks!

I've not done it, but have heard plenty about it.. carbs make no difference at all. All you'll need is a different header (2-1) and the can. However, from everything I've heard, you'd be better off (in terms of performance) going with Sarachu's. Beauty is subjective though, and if you really prefer the looks of the single by all means go for it.

When looking at a 2-1 system, be aware many will require removing the center stand and/or chopping into or removing the lower fairing.

The factory pipe has a crossover in it already. Someone may tell you that you can just block off one side and use the crossover to run all the exhaust to the other side.

Don't.

I don't know that I've ever heard someone say it, but when you start talking DIY it seems that anything goes. Plenty of aftermarket 2-into-1 pipes are available. I'd say DIY isn't out of reach (hey, it's only 2 pipes to tie together instead of 4, right? :p), but if you're going to try it then just do it from scratch. Just my $0.02.

Jardine, D&D, and Muzzy are all 2-1 options. It may be necessary to jet your carbs and go with a different air filter in most cases. Some creative people do manage to retain their centerstand.

You can keep the center stand if you have the exhaust go off the the left, but i think all of the 2:1 kits go right, theres a sh!t load of kits out there, see the end of the post for a link i found. I tore off my cans and fired up the bike without them, you have no idea the volume potential of this bike, haha. My buddy has a bored out mustang on straight pipes and my ninja was louder. Anyway, when i did this i realized that the centerstand rests on the left can when its not in use (noticed a clicking when i walked the bike without the cans, and thankfully the bike was off). The most popular systems ive seen on the 500 are muzzy and yoshimura. The price is about the same as sarachus, just gotta make sure you rejets cause with the 2:1 you will run lean. Make sure you post with how install went, im trying to decide between slipons or 2:1.

EDIT

Sorry, i spaced on the link, here ya go

My Jardine system went off the left side. The center stand was retained but the lower fairing had to either be cut or removed.

I would recommend the Sarachus because it's less hastle and I like the screws in the cans for easy repacking.

The '89 EX parts bike I just bought has a V&H 2 into 1 on it and the center stand is still intact. (Good thing too...'cause it doesn't have a sidestand.) ;)

I put on a D&D just the other day and as the jet kit and the pods had not shown up yet I decided to take it out the way it was and see what was up, aside from a small glitch or 2 the power band was pretty smooth and seat of the pants power was up enough to lift the front wheel off the ground in first with a snap of the throttle, something it wouldn't do before. The D&D is crazy loud I mean hurt ears loud if you start it in the garage, not to bad when riding. Once the whole deal is done I'm going to dyno the package and fine tune on the dyno.

Not personally, just going on what others have said and also the basic laws of gas flow - basically flow of anything - that says you shouldn't have a hard 90* turn when you want good flow.
