RE: GP exhaust on F4i
 

It's still in shipping rite now, but Ill take pictures and maybe a video when I get it and check it out myself.

Ohh ok post some pics up. So you bought it for f3 but you gonna put it on f4i? Will it fit in the diameter?

RE: GP exhaust on F4i
 

Not only the diameter but the bend of it as well. It has to be just right to avoid the swingarm and fairing. Im still worried about the back pressure....

RE: GP exhaust on F4i
 

From what I understand you can measure the backpressure through an O2 sensor bung. Im not sure if the f4i has an o2 sensor bung in an easy to get to place, but I think Im gonna go to an auto shop and measure before I try to install (If I find that the exhaust is reliable enough to install) and then get another measure after. You can do all the fine tuning of the baffle yourself if you need to increase/decrease backpressure. Im not at all worried about the design, or bends of the pipe, thats something that can easily be dealt with.

Keep us posted on that Scooby:D

This is what you get for $26. Included is a picture of the whole unit, then a picture from each side so you can see the baffle on the one side, and the exhaust packing on the other side. The whole thing came wrapped in saran wrap, and nicely packaged in a priority box.

2 of the pictures came out a little fuzzy, but if anyone is more interested I can take some more pictures and answer any questions. Im not going to get to put it on any time soon, its been around 105 with 100% humidity around here lately and I dont have any days off until next week.

RE: GP exhaust on F4i
 

Could you post some clearer pics? What does everyone think, does it look like there is sufficient baffling? Cant wait to hear how that sounds!

RE: GP exhaust on F4i
