c4 exhaust

(1/1)

Ausrs:
1987 convertible with flowmasters on it ,around 100 to 110 kph the drone is unpleasant  ,any ideas on the best way to fix it  ,what mufflers to change over to ? without spending to many $$

Scott:
Good exhaust shops can 'tune' the exhaust when they make them.  Normally they more the drone to a rev range that isn't used for long periods.  A balance pipe placed in the right spot may fix it, or you may need something more drastic such as moving or replacing the mufflers.  The hard part is finding a good exhaust shop that will fix it, rather than a generic one (midas etc) that will just want to sell you a new exhaust.
