Title: Exhaust db level. help needed
Post by: Red Leader on July 06, 2009, 10:22:02 PM
Right i have a twin turbo with std ports (FD) with de-cat.

I have to replace my backbox but need something that will passed track db levels, 100db or less. (I know they go upto 102db)

Have a RE dolphin tail at the moment.

Can anyone suggest either a cat back or down pipe back system the would meet these levels or does anyone have one for sale.

thanks

p.s im not a fan of the racing beat systems.

What\'s wrong with the racing beat systems? They look good, are well made, sound good at WOT, but are not offensively loud.  I wouldn\'t change my dual pipe RB catback for anything else I\'ve heard on the Market.
