Either of these are great pipes, I prefer the CMB AB.67 set at 11-5/8 to 11-3/4
The pipe can be gotten from Al Hobbs

Awesome RPM

CMB AB.67 Silenced Marine Tuned Pipe (Works well on 67, 80 & 91 engines)

Export Price: AU$ 122.75 Currency Converter Australian Residents: $ 135.00 (Inc GST)

CMB .67/.80 Nitro Marine Tuned Pipe (Large

Great thanks for the information I actually bought the ab67 from Stu when I bought the Cmb 67 I just wasn't sure big thanks for measurement that way I can make everything fit nice in the miss bardahl and at least be close on pipe measurement thanks again Jeff
