Default EVO Exhaust mod question

Ok

I kind of want to cut some off the pipes. Never been a fan of straight long pipes. If I hack about 8” off the top one...should I measure it and make the front pipe the same length as the rear. Giving it a staggered look?

Do what you want with it. Ideally, all header lengths should be the same. You are starting out with the front longer than the rear. These are not exactly hyper performance bikes, so cut it however you want it.

Also consider installing a couple of "lollipops" in the pipes, might get a little low end back.

Can be homemade or purchased. Check out dkcustoms for the manufactured ones.

I had a set on my last Fatboy. I’m wondering if that will help with the deep droning noise this exhaust makes.

Only one way to find out, and you can tune the lollipops by turning them. If you can weld, then homemade is the way to go, if not, you can still make them by using anything from thumb screws to eye bolts with a couple washers, of give DK a call.

Tons of pics and posts on the topic. YD

Default A word of caution

Be careful if you make your own lollipops. I used washers that were too large. It caused my bike to overheat and cooked the ignition. Now I have to spend $200 to fix my 50 cent mod.

Interesting. I have the 1 5/8 DKCustom TTIs in my Big Shots long which are 2", I believe and have not had any troubles.
