Exhaust option
I'm looking at putting my stock midsection back on to pass the MOT (emissions test) and maybe as a permanent fix, currently I have N55midpipe, evolve rear exhaust and evole decat dp's
I want to cut down on the noise of having straight through pipes as its doing my head in on long runs. Woul it be better purchasing akraprovich slipon with wireless system to mate to my current set up and, would the wireless flap reduce the drone? If I only put the stock mid section with secondsry cats on would this reduce the exhaust noise when on motorway? If I went for permanent fix, would I be better putting the secondary cats back on or purchasing hi flow sports cat dp's as a constant fix? Is it be better for the turbos if I just left the cat less dp's and put on the stock secondary cats I'm not fussed about loosing 10bhp or whatever I'm just wondering what the best option is! Car currently has 410bhp Thanks |
