muffler question I have a LS1, with AFR heads and a mild cam, currently putting 385 to the wheels with stock camaro manifolds.
I'm upgrading to long tube headers... 1 3/4" stepped to 1 7/8", to 3.5" pipe.
At some point in the future, I'll be going to an "enlarged" LS2
Anyway, it's time to decide on a muffler. I'm trying to decide between:
Auger type muffler,
and Burns stainless ultra light muffler.
the Burns muffler is $$$$. Question is... how long an auger type muffler do I need, and how much will it end up weighing with the pipe it's in?
How much power is lost through an Auger muffler?

I know your planning on "someday" building a bigger engine. But the headers are too big for anything making under 500 RWHP and 3.5" duals are just plain crazy unless your planning a 3.5" single system. Even 3" duals are overkill unless you wany looks over performance, by performance I mean usable power and tourque in the powerband you actually use and drive the vehicle in.
Power lost through a muffler is dependant on many things and can't really be cauculated, but a properly designed and sized system will cost minimal power on the top end and help build power on the low end.

The guy I bought the heads from was making 455 RWHP with long tubes on his vette, but my cam is not as aggressive as what he had.
I won't have but a few inches of 3.5" pipe (3.5" OD is what I measured on the header)... 4 into 1 collector, into 3.5, directly into the muffler and a short elbow after the muffler.
I appreciate your input though. Maybe I'll just move the engine swap up in the queue
