Magnaflows ir Flowmaster ls1 69 camaro im getting ready to do the exhaust on my 69 ls1. i used dual 40 series on my 70 with an ls1 but cant make my mind up on this one, any opinions about sound/hp between the two.

I personally would never put a "chambered" muffler on my car. I don't like the sound nor the restriction. I have had 2 different Magnaflow setups on my LS1 swapped car and they are great. Nice and quite at idle, smooth sound up top. When its at idle most people can't even tell I've got a V8.

i've got manifolds on my 69 ls1 with some 50series delta flows, the car sounds good but just doesnt do it for me when on the throttle. headers should help the sound some. i was thinking of switching out to magnaflows so im curious as to what others have to say.

running a flowmaster 2.5" kit from summit w/ delta flows (don't remember what series) ... it's a little quiet but it does sound good
I don't care about a little back pressure or restriction as mine is a street car
magnaflow has built a strong following, and the ones I've heard sound nice
