I am looking for a good SBC exhaust. I want something with good flow and that will last along time. I don't want to replace it every couple years cause it leaks

Revolution Marine.

Had a set on my 427 cu/inch small block, and they did great!

Motor produced 618hp at 6200 rpm.

Stainless Marine. No worries about leaking risers because the joint is dry. SM will also build any length riser pipe that you need and from what I have heard it doesnt cost a whole lot more than their standard stock riser.

EMI Exhaust is the best deal out there, good quality, good price. Call or PM and i will give you a great price.

Had these imco powerflows on this 500HP small block for about a decade now.

No problems other than being tricky to fit for my application.

They arent the cheapest units out there, but they've been great.

The best available.

Looks like CMI's- fantastic product

Lightning make a great small block true header as well.

True headers of are in a different price category than manifolds.

IMCO or Stainless Marine would be top picks for longevity, performance, and price. Let us know if we can help with prices.

For the money, hp increase, weight decrease from stock, looks and durability I found the Stainless Marine to be the best value....I was purchasing 2 sets though. In my application 99' AT28 w/350magMPI's-Bravos they added 200-300 rpms/1.5-2 mph.
For a single I might go with something more pricey...

I haven't seen the words "CMI" and "fantastic product" in the same sentence for a long time unless the sentence was "The CMIs on my 525s leaked and I bought Stainless Marine which have turned out to be a fantastic product"
