Think it would work? What have people here heard about gpr exhaust? I found a undertail slip on made for a 600rr for 208 bucks and i was thinking about taking it and having a stainless mid pipe made for it..... Do you think that would work?..... I want something thats going to be suttle but screams when you get on it....

thanks guys.....

 

This comes up all the time. It can be done on an F4i but it requires a lot of fabrication and turns out looking like crap because there's no way to route it cleanly. A RR swingarm helps but it's still not quite right.

 

there is what im doing as far as mounting... im making a custom aluminum undertail thanks to someone on here that did a write up on it... and im incorporating some of my own... im buying .5" hollow aluminum square tubing and doing that design around the canister.... which the canister will be mounted to... also im incorporating my turn signals and brake lights into it... as seen...... and i know the owner of a exhaust shop here in town that will make me a custom mid pipe... and he doesnt do things tacky so hell make sure its run cleanly...... i was wondering more about how the muffler will get along with the bikes computer and how the muffler will sound???????????????

 

The problem is getting the mid pipe to the can, I've seen it done but it looked like a$$. The mid pipe was routed around the outside of the swingarm.

 

that or if i decied to do a 600rr swing arm conversion... which only costs like 200 if that....

 

but i do realize routing the pipe on the outside and having it look clean is hard to do but i do beleive it can be done....

 

go for it and let us know how it turns out. search the forum to find some other tips.

 

another quick question what is the inside diamter of a f4i mid pipe? and what size pipe would you use if you wanted to say divide the one mid pipe into two smaller mid pipes and still have the same flow?????????????????????

 

actually now that i think about it.... is the only reason you cant run your exhaust on a f4i in between the swing arm and tire space? because there is a company that makes round to rectangle exhaust tubing... i could run it from the header to the muffler and now have to worry about clearance between the tire and swing arm...possibly

 

cmon guys help a kid out here.. anyone ever head a bike with gpr???
