Are straight exhaust pipes still concidered drag pipes if they are running baffles? I have a set of 2" straight pipes that have baffles in them but was wondering if I'm going to have to put the washers in them like I've heard drag pipes need.. Thanks

Straights and drag pipes were used as describing both,baffles or not made no difference.

I wonder if he was wondering if drag pipes with baffles perform as badly as open dragpipes. I wondered the same thing many times?

Got drag pipes on the 87 sporty, power cones and baffles, runs nice.

Open pipes kill the low to mid-range and make tuning carb difficult, especially on stock or mildly modified 5bikes. what are you trying to do?

rittchie66

tomfiii not trying to do anything in particular, ive got a set of staggared duels that look like straight pipes but have baffles in them, i was just wondering if i was going to have to do the washer trick for backpressure or if the fact that there are baffles meant they are ok

The washer install is usually only used on straight drag pipes. I've also seen (and used) just a straight 1/4" bolt thru the pipe. The baffles don't need the washer.
