no no what i said was that Turbo mufflers hardly ever really sing loudly because they have to MUCH BP unless they are put on a high Compression engine high HP Horse Power . but that they are not used on those engines very long because the BP is way to much for a high HP engine .. best way to explain this is this ... get you a straw put it in your mouth and blow through it . you can blow through easily ... no BP but do it again and start to slowly pinch the straw you will find you can blow through as easy and its harder that is BP and to much for a high HP engine if those where used on High Hp engine its would be like suffocating it ... so in my first post what i was trying to say was if you are looking for that deep hotrod rumble and if you are on a stock engine and stock exhaust manifolds then those thrush turbos will be pretty quiet because they have alot of BP in them ... not that you dont have enough ... so if you want a nice tone low deep hot rod rumble .. to save your money up and buy headers and some flowmasters of borla mufflers and it will have less BP which increases flow and HP and Tq
