Does anyone know if there is a 3/4 system or mid pipe available for our bike?
If you can't hear the exhaust it must either be good quality earplugs or you are almost deaf. >In standard trim I could barely hear the exhaust, maybe it was the ear plugs, but it is much better now, still with the OEM muffler. I haven't tried it at high revs yet, as I need to have the PC mapped on Tuesday, plus I don't want it too loud as that attracts unwanted attention from the blue gang.
Nice-Louder than stock above 3k RPM. No FI light.
Good quality ear plugs pushed well in, SR1 helmet, oh & 40 years in heavy industry all helps.If you can't hear the exhaust it must either be good quality earplugs or you are almost deaf. >
When I was ridin' the ol' B-King (with "open" exhaust) together with my brother ridin' the Gixxus (thru tunnels) I thought some part of the B-King exhaust had fallen of.
But it was only the sound of the *OEM* exhaust on the Gixxus.![]()
Mdala; I have swapped the OEM item for a carton of beer with Rebeard said:Thanks Mdala
Stage 1 of "OEM Baffle bypass mod" started today- See new topic with this heading.
Not the backpressure thing again.......would anyone advice against removing the cat ? and why ?
if the can is an open pipe, what gives back pressure to the engine as i wa thinking it was required ?
any videos with sound of someone who has removed the can , showing difference in muffler sound ?
thank you
There is a guy on this board with a full exhaust, PCV, timing alteration, and a dyno tune all for a 7 HP peak and 10 HP midrange increase at full throttle. The PCV alone on a stock bike is worth 4 HP from 6k RPM and up at full throttle and a 2 HP increase at most part throttle settings from 4k RPM and up. That's $300 vs $2000 for a 3 HP difference peak and 6 HP max difference anywhere at 100% throttle. Part throttle might be different. There is no cost effective reason to go full exhaust on this bike for HP. If it's a weight, looks, sound thing I guess but another $1700? Not for me.I agree with Gixxus. Do an internet search and learn about "backpressure" before worrying about that. People love their backpressure, dont they?
I have removed the cats from two of my kawasakis exhausts. I would not bother with it again. The material the cat is made from is super strong and a nightmare to deal with. Neither did much, if anything, and I wish I had the time back. Sound difference was not much, either.
We had one guy do a custom made "Y" eliminator for his z 1000. The before and after dyno chart showed a 1 hp gain..one hp with the cat removed. Big deal.
Modern exhausts are not horrible. Rather than butcher up a stock one, I'd get a decent header.
why $1700? Arrow headers are ~$600 so just that with a PCV which is about $300 and the stock can should get you really close.…but another $1700? Not for me.
