Talk to Dave at DA if you want b/c there are different options that you might consider
1. Front or rear exit
2. Size of pipe you can incorporate into your fuse (diameter)
3. Length you can have

I have 2 of the 125cc cans on my DA 150. They aren't much hevier than the 70-80 cc cans just a little larger in diameter and a little shorter in length (these are the rear exits). They dump right before the landing gear.

Any 2 KS cans 80cc or larger will do what you want but call dave at DA and talk to him if you want to find out more or order them.

If you have room (you should with an edge b.c the wing tube is higher than an extra), you might consider the tuned pipes. They add quite a bit of torque and are just as quiet.
