I wasnt calling you anything, I was asking a question....
I dont need to ask a turbo shop anything. You are absolutely right, the less backpressure the better on a turbo setup, no arguement here. The gist of MY point was that it would probably worth sacrificing a few HP to get the sound you want. You may not care, but im not going to run a Fart pipe on anything I have, I dont care if it gives me 50 extra HP.
And as far as "STRAIGHT THROUGH" mufflers go, you need to do a little research on muffler design and the effect acoustics have on flow, then youll understand that just because you can look through the muffler doesnt mean that there is no restriction.
One basic rule to go by, if it limits sound, it limits flow, so unless you straight pipe it, there is going to be restriction there, and I think you would be suprised how much restriction a straight through muffler actually has.
