Hi guys im looking at adding a janspeed to the car but i am unsure what i need i know that i willl need a back box what else? and a rough figure of cost inc fitting cost?
For full system you'll need 4 branch manifold, midpipe de-cat and back box. Probably looking at £500+ new. You'll be lucky to find any used these days. Fitting could be anything depending on your choice of garage.
on another note it doesnt have to be janspeed there are exhaust shops out there that can make you a full system from front to back you would just need to phone around and get some quotes. Good Luck! (Y)
