Get one bought son, I order you to do it now, GO!!
Cost is something you don't need to worry about my friend, just know this, it will look lovely
Lol it looks awesome and yeah you're right.. I'd probably go for a custom made exhaust, can get a decent one for £250 or so
But if you have to bring the filthy business of money into the game then around £320 all in.
£195 for the diffuser, £25 for the valance and £100 for it painted.
Oooh just thought while typing, you won't need the valance though so £300, actually £295 sounds a lot cheaper
I know of a nice Evoms for sale shortly lol
