Stm t3 exuasht mani

[TheGameTG]

Had anybody actually used this this mani?

What would be a good t3 mani and yes this probably has been covered before but there is so many company's that don't make manis anymore so there might also be outdated info,

dnp, erl, fp? Etc I'm keeping my power steering if that matters and I want some decent space around that area.

Ive used it on an hx40 loved it, great quality from a great fabricator, no complaints what so ever. Well, only that it didn't stay shiny longer, but what can you do. I had to sell it cause I'm going twin scroll.id highly recommend it, and if i wasnt a welder and working on my own manifolds now, I'd buy it again. Pic in my avitar has it. And here


I had a dsm flange dnp and my only complaint was that it was 16g tube vs STMS SCH10 pipe which is quite a bit thicker and what most other manifold users including myself use some others like toxic fab use sch40 which makes a really heavy beast of a manifold.

STM looks to be a decent quality manifold, but I'm personally not a fan because of the wastegate placement. The angle is too sharp and hinders exhaust flow. Is it going to be a big issue with controlling boost? Not really, but at the same time it is not a very efficient design. I am more partial to Punishment Racing's design with the angled wastegate tube for a smoother evacuation vs the sharp turn of the stm.

Will it block the power steering pump or alternator if I ever have to change it?

 

[lasthope05]

No, there's more then enough room.

 

[TheGameTG]

Both of them ? Or just the punishment racing one

 

[lasthope05]

I only know of the punishment. Call the manufacturer if you have questions about their product. It takes a few minutes to call them up VS waiting all day for member replys on the subject.

Stm was fine with power steering. As long as your not using a 38mm wastegate with an adapter, you need the MVR for which it was designed

Wastegate placement that bothers me are ones with 8+ inches of pipe before the gate, so much tuburlance with those designs. I'd say one weld el isnt the end of the world though.
