Alright now i've got a tough one. I've tried every forum and two trader websites and none have replied. And here's the question. I want to install a Mugen S2000 Dual Pipe Exhaust System or possibly the Mugen Accord Euro Dual Pipe Exhaust System (cause lets be frank mugen exhausts are top!). Now can this be done? And if so how much would the install cost be roughly?
