Well gents, I just called Chris at moto gp werks. And he said he litterally sold his last cb 750 yoshimura pipes this morning! But he has some 4->2->1 pipes. He said that he will be making another batch when he has 5-6 guys on the waiting list, and said that it usually takes 2-3 months to get a waiting list for them. I put myself on the waiting list and in reality it will give me the time to finish my engine and save up some money to throw at him. I'm really looking foward to them!
You may also ask him to weld on a support bracket for the end section of the pipe.  You don't want the weight of the headers being supported by the head alone.

Don, Chris's 4 into 2 into 1 already has a bracket welded on for rear support... ;)



I think my post was unclear.  I was referring to his 4-1 for which the original poster was going to get on a waiting list.

I've got the Carpy's and they leak with the crushed gaskets. I haven't tried to seal it off yet. I would try an alternative, although I do like the sound.

Thanks for the input guys, to be honest I don't use the center stand to much. I am not attached to Carpy's stuff, looks cool but he REALLY sucks to deal with. I was looking at moto GP werks website but I can not find a like to their pipes would you be able to point me into the right direction from here?

how much did the Moto GP pipes run you?

+1 on the Moto GP Werks !! Build Quality is awesome.. They are only built in small batchs. I had to wait 4-6 months to get in on the next available run of pipes.. In the end, worth the $ & Wait !!

I found his "ebay store" and bought from there. $550 range.

I've bought two pipes from Carpy, the first one a CB550 pipe three years ago. I couldn't get it to fit to the head at all. He did take it back and refunded my money. I tried a CB750 pipe from him last year and it fits perfect, sounds good, and I made a homemade bracket to secure the tailpipe.

Oh, and the MAC pipes sound like a choked engine through a tin can (IMHO). I have one on my 550 and hacked off the megaphone and installed a reverse cone.

The old Kerker headers from the 70's will work with the center stand, if you can find a set. If I remember right they sounded nice.
thanks, Mark
