Pepi, The reason I'm not going with straight pipes right off of the collectors is that the folks building my car said it would sound funny because when you drive by someone all they hear is one side of the exhaust & it sounds like a 4 cylendar engine. And after they mentioned that I remembered a friend of mine who drove by me {in a '30 Ford with a small block & straight out pipes} when I was standing downtown & I remember it sounded a little 'funny'. So I went with mufflers that are 'tucked' up under the frame & pipes that exit out back.... Bill
