RX1 Exhaust mod

[polarisconvert]

For those of you that did our own exhaust mod, (cut and removed pipes on factory muffler) are you happey with the sound. Also one guy reported he lost 10 mph on top end. Any body else have proof of performance gains of losses after the mod?

Thanks Bruce

Did you take any pics. From what i remember seeing on this site there looked like 3 or 4 tubes in the middle and they cut them all out?

Hum... Im still debating, I don't want to loose even 1/8hp by doing anything to the sled. I know these machines are built to run with the exhaust thats on them and aftermarket companies have the capability to research and dyno different setups to make hp but yamaha paid some engineer millions to design this system to run good with the motor and still be quiet. If I could make it a little louder and sound good and still keep my hp where it is or gain Id do it but Im no engineer so I dont dare mess with anything for fear of loosing power...

I am with you. Need more info.
I have always put my money into hp before sound or looks. Would hate to loose any power.

all i can tell you is when my exhaust broke at the x crossover it was instantly much quicker than the other 2 2003 rx-1's and the 2005 rx-1 i ride with.but silly loud.

Use the White Knuckle QC1 sounds nice lighter and gains a couple ponies.

do a spark plug chop before and after you will see a difference.
