I originally had the oem exhaust and you can get expansion brackets from Capristo that will pick up the bolts where the silencer attaches to the tail pipes- to fit these you have to remove a few of the oem brackets, including the one which cracked on you. Look on Capristo.de. Goto the 430 section and look for a pic showing the brackets to take off, in order to fit the exp bracket. Moving on, i now have capristo manifolds and a non valve silencer, this uses a similar exp bracket. On a good run the expansion bracket will pick up 18 mms of movement, yet the oem setup restricts this.
