Cl450 Exhaust Back Pressure?

[RockenRolla]

Hey guys I have a 71 CL450 and the pipes are in pretty good condition except the mufflers, which are extremely rusty and one has a good size hole in it. I wanted to just chop them off and just have a straight pipe, but im not sure if it needs the back pressure. And if so then what do I need to do? :-\

If you take the mufflers off then you will run loud and lean until you put a hole in one of your pistons, at which point your motorcycle will be very quiet indeed.

Also, here's the best resource I've found to explain what "back pressure" really means:

Alright thanks makes sense, so what should I do then? Because the mufflers look god awful atm and are really loud due to the tennis ball size hole.

 

[Rich Ard]

I would humbly suggest that you put new mufflers on it

Or find someone with a spare set of pipes and buy them.

Your motorcycle. Unless you want to do a good deed.

And too bad and two months late. I just sold a pair f CL450 pipes to a guy who wanted to convert them for a 350. Were in good shape only lil pitted. New ones list for 930 pound from England. 1500 local dollars at least. not selling my new ones yet.
