Sport bike Exhaust options
« on: December 26, 2018, 09:17:53 AM »
Hey guys,
I'm in the planning stages for my Busa swap and exhaust kinda crossed my mind. 
I kinda want to keep it low key-ish.  Has anyone ran a Flowmaster or even a Spintech type muffler on a sport bike?  Any thoughts? 
The sportbike slip on mufflers are STOOPID expensive.

Thanks

all sport bike exh is stupid expensive imo.  all the n/a engines i ran i just went 2.25" exh tube right off the header and ran a super trap. i always left all the plates and cap on the super trap but spaced them each out with a small thin washer. idles very quiet and really not as  loud  as one would think at higher rpm's. the busa has a dual exh but very simple to merge the header and then go 2.25" all the way to the muffle or tip. again between that and cold air intake this is where the bazzaz comes into play .

The busas use a x pipe and then on to the dual muffs. Not really a dual exhaust. Nothing wrong with using a single muffler IMO

Yep, I have the stock x-pipe that I will dice up into 2, 2" pipes that will go up behind the trans, 90* over the new center spool into a dual inlet Flowmaster with 2" inlets and 2, 3" outlets that will dump out in the center if the car.  It should look pretty killer.

Theoretically,if you merged the 2 pipes before the muffler you would enhance low rpm torque. Then use a single inlet and outlet muff.

I have been known to run no muffler, just single exh pipe dumping out 12,000 rpm.  :m

But even w a small s-trap knockoff it did know down idle noise.

But best exhaust is thru a turbo, thats my recomendation!!
