08 GSXR 750 Hotbodies megaphone to M4 GP Slip on

I had the hotbodies megaphone slip-on on my 2008 GSXR 750, and wanted to eliminate my catlytic converter, so i used an 06-07 M4 GP slip-on, which connects right to the header. I had to cut off the stock cat, and the total weight with muffler was 15.5 lbs, and the M4 slip-on weighs only 5 lbs! Not as throaty a sound, but screams pretty good.

How did you line up/ bolt the m4? I have an 08 Gsxr with the stock muffler but scared to cut the stock cat and not able to line up the holes to mount it on the bike.

the worst case scenario is that you might have to fab up a little bracket or two to line up with the stock holes. The M4 had a big enough flange on the can that I was able to just drill new holes and bolt it on.

Was it An Easy Install? Im looking to put one on my 2010 Zx 10r, but dont know if i should take it to a mechanic..

@BloodBathFour

If you are somewhat mechanically inclined it shouldn't be a problem for you. Im not familiar with kawi's exhaust setup, but it can"t be much more complicated than the gixxer's SET valve nonsense. With the right tools you should be fine.

will 2 bros work 2

@antonyM2007

yeah i think all 06-07 gixxer slip-ons will work in the same fashion because they all come with a sort of "mid pipe"

Well I did the the install this morning,I think overall the longest part was putting a bevel on the header...I also made the mounting holes a bit wider like you said and it worked perfect...thanks

@notthebread ok kool beacuse, they only problem i think i might run into are my cables that run up into my seat. you think i would need a power converter to map it out, or i'll be fine with just the slip on?

What did that do to your torque? I just sold my 636 and plan on getting this same bike. I put a muzzy slip-on on my 636 with no tune, and lost the already dismal amount of torque I had, I literally couldn't power up in first gear anymore. I want a K8 750 but the main reason is I want torque, and I don't want to lose it. I'm going slip-on, sprockets, PC5 on this bike when I get it. I want a slip-on that keeps torque around stock levels, or increase it if that's possible.

I made a little bracket and just screwed it to the thin flange on the stock catalytic converter, and I agree, gives it a cleaner look, you dont see that ugly clamp setup..
