Ok so I guess ill be the guinea pig lol after I get my taxes ill dyno before and after maybe mid next year it should be finished with the body kit painted hopefully...

Find me a bike that makes 200+ bhp, and use that exhaust. You are going to have extreme piping issues even if you are headed back changing it up. Street bike exhausts are made to keep you safe, on a car it is just silly and is in the same category as whistle tips.

The reason I even thought about using bike exhaust was to get a center out exhaust using probably 4 street bike exhaust cans faced toward eachother with a collector or custom bent tips and have 4 pipes out the middle

Like this?

No more pipes then that so the airflow will be perfect..

actually you can.

to my question or to the 50 pipes on one car? Lol

This thread makes me sad, I came in expecting your G with the pipes already on.

Haha no its just speculation and planning at this point hopefully next year ill get it done and I will definitely post pics and stats

sounds a bit silly to me but you've piqued my curiosity, so if you actually make it happen please do post a vid of how it sounds, and dyno sheets to see how it affected power.

^hahah

Seriously, man, enough. Look, I've wondered why they can make a Harley or sport bike so loud with only 2 cylinders, meanwhile a 1.9L car motor sounds like **** when you put an exhaust on it. Bottom line is it has to do with piping. There's no reason to put a motorcycle muffler on your car. You may think I'm just being a hater, but if you want a unique sound have your pipes come out of the sides of the car before or after the door, maybe put a resonator in there..whatever. Come up with something made for a car. The other will be a total waste of time and money.

I think he is trying to say he wants to run his pipes like this

That's all good, then just get an inline muffler with multiple dual outlets and get two double tips and have an exhaust shoo bend the piping. No biggie. No reason to use motorcycle mufflers tho.

BMW HP4. Uses Akrapovic exhaust which isnt cheap. A full Akra system for a bike is more than most high end systems for a car. Its ridiculous!
