gpz exhaust

was wondering if there was a new 4-1 exhaust for an 85 gpz 750 other than mac. cant find any others for direct fitment.

I hear that the kz 750 pipes will fit. Kerker makes one. There is an x-pipe on ebay too.

The ZR-7 exhaust also has been done, but is HEAVY. On another site, there is mention of a ZX9 exhaust being hooked to a ZR7, so by reverse thinking, that could work.

Definite on ZR-7. Not so sure on zx9.

I don't think the ZR-7 system weighs more than the standard 4-2 exhaust of the old KZ's. It is kind of heavy though... It certainly weighs more than a Kerker 4-1 exhaust.

One big advantage of a ZR-7 system is that it's made from stainless steel, So it looks really good.
But if you want the look of the old style megaphones (Kerker etc.), you should get another system.

You can also look for a Zephyr exhaust. This would fit the cylinders, but you might have to fabricate a hanger for the muffler (the same with a ZR-7 system)...

thanks for the advice guys. i have decided to go with the mac ,im putting a d&d can on it. of course i will be rejetting my carbs and adjusting the float levels as it floods on start up now. its agrivating next i will go with the dyna coils and s2000. so hopfully there will be no more starting probs.
