my 04 sti uk has heyward and scott headers and a prodrive exhaust with sport cat. Today i thought "god this is quiet" with the sterio on just a little you cant hear it on tick over at all. Looking through receipts today i found one for an inner silencer for 40 pounds ( no pound sign on key board) has something been put in the exhaust?

Dan-

mines the same! but its quite loud outside is yours much louder than my 1?

only got the prodrive system on mind you

It could be the sport cat making it quiet. Have you thought about a H&S cat replacement pipe?

no i havent, could be an option. I need to find out id it has had a quiet core fitted, where will it be if it has had one ?
