My husband and I just ordered a 2002 Dyna Wide Glide. We are suppose to get it in Mid-June. The first thing we plan to do with it is get rid of the Factory exhaust and put straight pipes on the bike. We are looking at Sampson Big Guns 2 straight pipes. Does anyone know if these are good pipes, personal experiences, etc. Also I have heard we need to rejet the carb. Should we recalibrate the carb using a carb kit or would a Yost power tube be better? I would like several opinions as to what we should do. What would be best...pros and cons..etc. Any help is greatly appreciated.

Straight pipes are hard to tune and you lose quite a bit of midrange power.


The smart thing would be to keep the crossover and use inexpensive Cycle Shack slipons. With the money you save you can buy an air intake kit.

You need to rejet the carb, but 5 bucks in jets and a few small washers from the hardware store are as good as any kit.

It will make for a stronger and more pleasant bike to ride.

If you are willing to give up performance for looks, by all means, have it your way.

The magazine Hot Rod Bikes has tested tons of pipes on the dyno over the years and they all fall within several horsepower and foot pounds of torque of one another. I suggest you go to a big bike event and look and listen to a variety of pipes. That might help you make a decision. Samsons have as good of a reputation as any. You might want to first try some slip-on straight pipes to see if you indeed want to live with the noise of straight pipes. Some styles of aftermarket pipes can't be retrofitted with any sort of baffling or mufflers so if they are too loud, you're stuck. Be sure and retain your stock exhaust so you can always go back. You will probably experience a slight dip in low speed torque with straight pipes but thats somewhat offset with higher top end power.

Most any pipe or air filter upgrade will require rejetting. Yost, Thunder Jet, Dynojet, etc. all do about the same thing - enrich the mixture. IMHO buy the cheapest kit that includes jets, drill bits and a slide spring.
