Default Subaru Classic H & S 2.5" Backbox

Anyone have a Haywood and Scott 2.5" backbox, the replica of the Prodrive exhaust, on their classic, just the back box with both cats still on? Is there a sound improvement?

Thanks

yes, it will sound massively better than the standard backbox without being overly loud

when I got my car it had a very loud (Cobra) exhaust on, which was not to my liking, I swapped that for an H&S and it's so much better in both looks & sound

this is how they look fitted >>>






you won't regret it

I now have a decat centre section, but still have the cat in the downpipe, so it's slightly louder and gives more power, but still passes the MOT

even with both cats fitted it still sounds a lot better than the standard backbox
