Hello another question--I have a 74 850 commando that I would like to put new pipes on. What is the best brand of pipes to use and where do I get them. Should I get them with the crossover or not. I have heard the crossover can improve the horsepower a touch and that it helps to keep the pipes from vibrating off and damaging the exhaust threads in the heads. I want good flanges with he3avier metal than the cheapie knockoffs. Should I use 1-1/2 or 1-3/8 inch pipes??? I have heard that the MKIII pipes that use the split inserts and conical do not allow the exhaust nut to catch as much thread as the crush washer flange type??? I want it loud and proud and I intend to use strait thru pipes on it. I want good chrome and do not mind paying for it. Does anyone have any pros or cons??? Thanks for any suggestions.
