So, after runninga bit with the LA Chopper slip-ons I decided to go back to stock pipes. The highway volume became so obnoxious it rattled my eardrums out! The helmet seeemed to make the volume louder- more than I could take. Too bad 'cause I liked the rumble of these pipes at idle and throttle blip.
Also, so after putting stock pipes back on and taking a small roadtrip this weekend I realized another issue (I had installed a jet kit to tune the pipes)- gas mileage went down considerably! I used to get 42-45mpg and on this 300 mile trip I only averaged 28-30mpg!!! Jet kit is coming out too.
Oh well, I guess it's not such a good idea to re-engineer/mess with what's not broke.
