I bought an 4" super cat cannon exhaust for my mates ke70, We've currently cut off the stock muffler box (and yes At the moment it sounds Mental :P) and was wondering if we should weld the new cannon to the stock old pipe?

i hope you realise you will gain 0 power from doing this

why not get new system?

will get more power and sound less like a 2 stroke

Wrong way round Lexuskid-

 

Get a big pipe and a small muffler.

 

You can always change mufflers easily, but with a stock exhaust size you won't get flow gains.

 

Go get extractors & a larger pipe, then use a clamped joint to fit the muffler.

 

Then just keep changing mufflers until the cops stop harassing you!

Ohk, well I think that's the plan for when he gets some more money, I believe his planning to run a 2 1/2" pipe from the extractors back and then he really wants to attaching a dump pipe.

2.5" is too big. Go 1&7/8 or 2" at the very biggest.

agreed i had a 2 inch press bent so it was practically a 1 7/8inch system and it was perfect

guys hes not asking about more power!!!

hes asking if its ok to weld the cannon to the straight pipe

now the answer is yes BUT you should have left the stock muffler box and just cut the pipe back so the cannon doesnt stick out too far

you are clearly after noise and you will defidently get it from welding it straight on now

hope i helped

Yeah cheers all,, I think for the time were just welding the cannon on until the entire exhaust system can be done

There's a guy at my tafe rocking a 2 a half inch on his bog stock ke70 apparently it sounds like shit.
