I was talking with them at one time about EFI. Didn't know they did exhaust. Guy went ballistic when I asked a question about exhaust. I would weld up my own before buying any from them. And I don't know how to weld. One of the nice things about HDs is that there are many choices. Some are good to work with and then others are #$% &#$%. The ones that are good to work with will get my money.vharrig said:Does anyone have any experience with these pipes? I'm looking to add to my bike and it's alittle confusing with all the manufacturers out there. Kind of stuck between the Thunderheaders and LSR 2-1's.
