What i want to know is.. I got some just basic stock exhaust pipe at the surplus store for 9 bucks. I took off the mufflers and put these pipes on just like you would some harley davidson slip ons. I can install baffles in them if i want that's no problem. but i made the slip ons about 22 inches each. It's loud and it seems alot faster. but how will this effect my motor? do i need a computer upgrade, will harley even upgrade since the things i slipped on aren't harley? should i do a high flow air cleaner? any help will be greatly apreciated. what i'm gonna do if these pipes will work for me, just wrap them with exhaust wrap or powder coat them black, to match the rest of my bike. thanks for your time
