I have just purchased a 2005 zx6 full stock system. I plan to install it on my L model, As a neat underseat system with the added benfit of titanium headers and an exhaust servo valve. Hoping to use the valve to tune out the big hole at mid revs caused by the cams and tunning work. I am expecting to have to do some work and cut open the mufler . Just wondering if anyone has attempted this or any other underseat conversion. I am going to remove the anti squat bar and weld a filet into the swingarm. Also going to buff up the titanium headers and possibly make a new collector......any input welcome......cheers.

incidentally I will have a beet / nassert straight through system for sale if this works ( 4 - 1 full race) any offers ????


Regards TK400

Troy - there was a really neat underseat exhaust sold a few months back on e-bay. The rear subframe was modified with a cutout and removeable "spar" which allowed the exhasut to be installed but when replaced maintained the strenght of the subframe.

I was tempted at the time but had other priorities. I think I copeid the pic - will have a look

Surely the 6R pipes will be way to wide, taking the very little low-mid range the bike already doesn't have?

This chap in germany has managed it

Wow - that zorsts a work of art. Hes cleaned up the back end nicely but ditching the rear brake might not pass scrutineering!!!

by way to wide ...do you mean diam. Its actually not bad for race spec zxr400 and it is 4-2-1 which is gunna be better for road/track day bike. I just need to remove the cat which is in the collector and make a new collector. Just picked it up today and it doesnt look bad........

fallsofslowly is trying this right now, im sure if you asked him he advise. top pbloke he is!
