New exhaust
I want to get a free flowing exhaust for my 159 1.8, ive looked around MIJ Performance custom make them, does anyone have information about MIJ, or comments as to how good their products are in terms of engine note, power gain.
There is a backbox on Novitec website for €270 odd euros, but will this just be a sound improvement if i dont replace the stuff further up?
Is a "cat back" system, replacing all parts from the CAT converter backwards?
