as far as exhaust goes i have the hatori 699 which is a sweet pipe. The only header that i know is compatible is the hatori cooling manifold.

As far as the mount goes i have the gator soft and safe mount, which is ok, but the rubbers need replacing about every 50 flights, which is a pain. If i could be botherd i'd have spent more initially on some flash mount which would do a better job.

Must admit the C140 will be sweeeeet with that 160DZ, just even more pricey to run and takes longer to fuel up!
