Merc 2.4 Exhaust Tuner Difference
One tuner has lengths 10.25/11.25 and the other 11.25/12.25. Powerhead is 91 2.4(fatblock 200 xri with head work and bucatto) . The mid on boat has the longer lengths. Should I go to the shorter one(while thing is apart) or consider a Bob's(which hurts with the Canadian dollar and shipping) .

Should I skip a Bobs and go with the one that only requires a gasket replacement?

The short tuner and the Bobs perform pretty much the same. Doubtful you would be able to tell the difference between any of the 3.
