Tru-Ram® LS1 Exhaust Manifolds, Unpolished

I would buy these manifolds again when needed.

These manifolds worked great on my car.

did not work on my 68 Camaro

product quality was very good ! didn't work on my 68 LS swap with stock steering box. customer service was very good.

Perfect fit and nice craftsmanship

Used these to clear the clutch hydraulics on an '86 K5 blazer LS swap. They worked perfectly and leave tons of room to spare. These should also easily clear the Me Hannibal linkage on the '73-84 models.

Exhaust Manifolds of My Dreams

I am building an LSX engine with solid roller lifters and shaft mount rockers which necessitates tall valve covers, and I wanted to mount twin turbos right on the exhaust manifolds but the first set of manifolds would not clear my valve covers. Now, I have these wonderful manifolds. So freaking awesome!

High quality manifolds well thought out and designed parts

Using these for a slightly unconventional ls swap on 68 C50. These are a most to create simplicity when placing motor mounts and cross members.

These are the second set of Tru-Ram I have purchased.

These must be the tightest fit, best flowing cast LS header available, and the only ones in stainless steel, for better appearance and longevity. Casting and straightness are excellent, some minor filing on the bolt holes for match-up. Same casting left and right, with good access to spark plugs, and around starter. I like the 3 inch outlets, and standard three bolt collector in the casting. These will work well on custom LS installations.

Look good

Appear to be good quality, should last forever.

Great company to work with

Very good quality

Perfect fit for my custom application.

Awesome products and would def use this place again.

first rate product that is different from the rest

These are different than all other aftermarket cast manifolds in that they are an offset center dump style, rather than dump back into the firewall like all the others. Far nicer for keeping exhaust heat away from the firewall/floor !!! Why don't the other brands (Hooker, ect.) use this configuration ??? My only complaint is the 3" outlet, as most street systems used with manifolds / shorty headers are 2 1/2", which is plenty for the flow/power potential of these parts. Very good product, though.
