Some of you may be aware that I am getting tired of my Cat Back exhaust. I think it sounds fantastic and one of the best sounding on the market, but the old man inside me finds it a tad loud. Current Exhaust is the Cosworth 3" cat back. It measures 92dB using the 1meter/45degree test, so not exactly loud but I find it undesirable on longer journeys. This is not the crazy loud full Cosworth exhaust some of you would have heard at the open day - this is just the cat back. My aim is very little noticeable noise on the motorway. I dont mind a little rumble, but with the current setup small amounts of throttle and it gets loud/boomy at 3k rpms so its okay when cruising on the flat but any hint of throttle to overtake or go uphill and it gets boomy. Its a subjective thing, and many don't consider this to be "loud" but I do and have decided it is time to swap it out for old man mode exhaust. Current list of alternatives are: Invidia Q300 - very quiet and popular with people that swap the manifold out. You tube videos vary. Some it sounds quite loud and other it sounds almost stock. Miltek resonated - You tube videos make this sound louder than the Q300 with a more bassy tone. Bliz Nur Sec C-TI - very quiet but small bore and chamber type back box makes it as restrictive as the stock back box. Ear plugs - Cheap and effective but then I wouldn't be able to hear passenger talking to me. Custom - could ask H&S to make me a massive straight through back box and fit a large silencer in the mid pipe. Might be expensive but also might be able to retain the "3 piping. Does anyone else have any real world experience and possible alternatives? Budget up to £1k
