Slip-on Exhaust

cablerum · 05-13-2010, 06:53 PM

Hi, I have a 98 Kat 750, still has the stock exhaust. I was thinking of adding an aftermarket slip-on. Just wondering 2 things. First, I would rather not have to do anything with the jets or carbs & second, is there a preferred brand or model for 750 kats to give the best sound or performance? Any ideas or suggestions? Thanks!

You won't need to do anything with a slip-on exhaust. You just put them on and go. Nothing else is required.

The preferred brand is the one that sounds best to you at the right price. For my former Kat, a Good 'ol D&D was the best because I liked loud and cheap, just the way I like my women!

Theres a yoshi RS3 for sale on the forum for $150.00. Great sound, not super loud and you'd be getting a GREAT deal on a yosh system.

I love my D&D but my first Kat had a Hindle and that was really good as well.

How does one have 22,000 posts and still reply with complete bull**** advice? This is just wrong.

Everytime you change the airflow either into or out of your engine, your fuel needs change as well. He'll need bigger jets for sure. As a matter of fact, I'd be surprised if the bike ran well at all after the change. It would be running dangerously lean and he'd risk damage to his engine.

From my understanding the most restrictive part of the Kat’s exhaust is not the muffler and mid pipe but the header tubes. I can speak from expericane that you can put a slip on on and not adjust the carbs from factory at all. A lot of people will adjust the A/F mix screw but that is it for a slip on.

Neg. There are plenty of Kats here with slipons that perform just fine without rejetting..

Kids, kids, stop the bickering. Actually some of the "street legal" mufflers are even more restrictive than the stock part. Thus "need" no jetting. You could benefit from a jet kit but that could be said of a totally stock Kat.

Yea, your right (I suppose). Although, I have no idea why anyone would purchase an aftermarket exhaust if it didn't provide more air flow. The stock dual pipes are a pretty sweet seamless design. I suppose it's possible someone could put on an aftermarket system with the exact same air flow as stock.

So, to clarify, if you purchase an exhaust that increases (or decreases) flow through the engine, you need to rejet.

WOW, sounds like it's up to you! Slip on for better sound and looks, re-jet for more power and drive-ability. Or both for the best of both worlds!
