Exhaust System for my 70 longbed BBC

[70chevytruck]

Just had the big block rebuilt...need a new exhaust system.

what does everyone recommend?

I am thinking 2.5 inch with flowmasters. Stock manifolds...anyone make a stock exhaust for these trucks that just bolts up?

I went single on mine. 2.5'' out of the manifolds to a flowmaster y pipe connector then into a magnaflow 3'' and out the back behind the drivers side tire. I got rid of the previous owners leaking headers and duals. Really cleaned up the underside of the truck and sounds great. Next, I'm gonna get rid of the 750 holley, what a piece of crap

Not to thread jack, but do you have any pictures of the y pipe and routing? This the same idea I have.

I saw a couple of places that sell complete systems but I am concerned they would need modifications....definitely want to keep duals out the back with a couple of decent mufflers.

Anyone else?

Have you checked Magnaflow?

Checked Magnaflow but price seems a bit much and the only one I found was stainless....I just need inexpensive.

I bought a kit from LMC. Pretty sure it is a heart throb kit. Its all mandrel bent. Fot great after i figured out that all the labelling was backsard left to right. It was under $300 but the head pipes are for a sbc with rams horns. I am sure that bb manifolds are different (?)
