Hi guys. . I am wanting some information regarding Cans.. I am wanting to put some slip ons on my 1100XX b/bird.. I have priced yoshi, D&D and others.. I have been speaking to a Guy in Brissy that can order stainless Bike Cans.. Barrell Size 5.5" x 4" Oval -18" Length - 54mm Pipe Size.. I can Get these for $130 ea (cost price) and he can make the Mid pipe.. My question is Should i go the "Straight Baffle" Design or the "spiral baffle" design.. What would sound better?? they are supercat performance Cans.. Any Reccomendations or Review Welcomed.. Thanks Heaps.. Stewie BlackBird Pilot..
