X2  Your motor should stay together pretty decently but it just will not be the most powerful it could be.

I had a buddy who ran a CT 500 with their outlaw pipe and he liked it but we switched him up to a Paul turner, V-2 reeds, a dry filter, and the 85/86 OEM clutch springs and he likes it much better.  I think it does have some CT porting on it but not 100% sur eon that. 

I can say it's a strong runner for not a lot of $$$ in to the bike.
