Do you get any "backfire" from your bike with this mod? If so, should you do the marble mod? Thanks

My stock cans are modified and have been since just a few weeks after buying my Busa in August of '03...I've had 'em backfire maybe 4 times in all that time...no issues with 'em, they sound better than stock

 

[NiTrowood]

no back fire at all.....and yes

when i did mine 1 driled 9 holes and cut the center tube down 1.5" sounded super cool and deep

 

[KanjiBusa]

Will it backfire at all cutting the end center tube down 1.5 or 2 inches? I just dont like that stock look..

 

[ranman]

i had no backfire problems

Well, while I was waiting for the shop to mount and balance my new rear tire, I did this mod to the stock cans. All I can say is "COOL"--wakes up the sound a little. Cheap man's Muzzy! Thanks to you guys for the info on this one.

Just finished doing mine too! I love the sound, although I still can't wait to get a set of Yoshi's on there.

I took mine apart and welded in 2-1/2 inch straight pipes in mine.Sounds awesome and lost no power according to the dyno.A fair amount of work but im a cheap Mofo.Hee hee

I did something similar....................I am also a cheap bastid......... No just broke................
but I used 2" exhaust tubing and made a baffle for each side by cutting slots perpendicular in the pipe about 3/4 deep along the entire length and around the circumference, then I used a punch to bend the "baffle cups" down .I also drilled 1/4 holes the entire length in between the baffling. I cut the end plate of the stock can with a 2" hole saw, gutted the can, (hard part) and welded the baffle here. The other end is flanged to meet the mid pipe.
It kinda looks stock but sounds much better.

It was very labor intensive and I did not cut the cans at the end.
Heres a pic:

just did mine. wow sounds way better than stock. who would think it would make such a difference. all i did was drill 6 1/2 inch holes. amazing. i think ill pull the caps back off and cut down the pipes. i left room to do 9 holes on each, probably do that too. wow.

 

[ranman]

cut the tube down 1.5" worked cood for me

 

[thecrackhead]

cool ill cut the tube down tomorrow. one thing i noticed when i just took it for a ride, Im hearing an air sucking noise. im guessing its the pair valve? was kind of weird. happens whenever you rap on the throttle, but yet it feels a little quicker now.

i really like the stock can mod.... did it to the bike on friday. love the deeper sound and especially since its a lil louder... did the 6 holes, but another guy on here said he did 9 and liked it alot better so might try that tonight...
