shortened a middle exhaust off a small japanese car (the middle exhaust is straight through unlike the rear exhaust off a car)

would have liked a bigger tip but tried one and it was too loud and when i took it for a test ride there wasnt enough backpressure and had a really bad flatspot down low

That's very interesting...it would make an neat alternate exhaust project for when I don't want the Two Bros hanging off the side.

Post up pics of it once you get the heat shielding on

Unfortunately, if I ever do something like this, it would only be for an occasional change of pace and not necessarily for long term use. I would have to see how it would effect the fairings and what not.

I think it looks good, definitely different, good work. Im a big fan of exhausts like that but i dont think id ever have tried to cut down a car muffler but hey whatever works. I hope youre gonna polish/paint/pretty it up in some way.

Looks fine to me!!, i always wanted to do that but i've seen a video on youtube of an f4i with a similar muffler but its smaller and of course louder. That's why i havent done that, too much noise will make my head to explode.

So your design is quiet or how much loud it is??
