$560 installed. If you get it done from walkinshaw they'll put the small sticker on your car or the one i got for an extra $20 and you'll get a "certificate of authenticity" as well. They also sell the small bee sting antenna for about $20.
never heard of remus before hey,
ive heard the xforce staino ones sound real tinny i was talking to a bloke at a local walkinshaw dealer, he reckons the mild steel one isnt to bad though
how much is each worth?
at JHP they'll install mild steel for $992 and stainless for $1399. keep in mind though this is only for the 2.25" system, anything bigger will obvioulsy cost more.
