I asked Rob for a set of aluminized pipes to cut the cost of his quality work but I doubt the change. You guys who have shown little difference with electric cutouts with GOOD catback systems shows there is power to be made with the resonator/muffler area. An X-pipe in place of the rear cats, deleted resonator nd a BORLA #400482 muffler could yield my car 25HP. I am pushing 20+ PSI of boost now so it(the echaust) is something to look into. I am going to take 2 months before i do any other mods so i make the right decision having limited funds to work with and taking time for research and asking questions of the more experienced.
I guess I could work with the stock downpipes or have a set of custom pipes made. I like the quiet of the Mercedes and should try to keep it that way while making those 25 horses lurking, waiting and readying to burst out!
For the guys who have been down this street before any things to go with or those to avoid would be appreciated. Thanks and even weak opinions are needed at this early point in my quest for 25HP from the exhaust change
