Default For those of you with TWE headers..

..did you end up going with Super Stock (1.625" tube/ 2.25" coll.) or High Output (1.75" tube/2.5" coll)?


Thanks in advance!

the only reason to go with high output is if you plan to turbo later on. which isnt a good idea any... unless of course its a swap!.

or if u are planning on doing internal mods with raised redline, i think u'll lose low end power if u go w/ larger diameter exhaust system.

even with cams or heads the Super Stock will work very well. Call TWE and talk to them.. they will help you out..

I have talked with a few people about this. The Superstock is probably the best choice. The High Output is if you are building an engine that is probably only going to see time at the track for drags or auto-x. If I was rich and had a lot of money it would be a closed forged ej25 block, titaninum pisitons (12.5+:1), titanium rods, cai, pnp heads (stage 3, no daily driver here), either stage 2 or 3 cams, thin head gasket, pnp throttle body, knifed and balanced crank, 04 intake manifold, larger injectors, larger fuel pump, High Output header, catdelete racepipe, a 2.5" catback exhaust, stand alone system (probably link or hydra for better fuel, timing, and raised rev limit to around 8-8,500). This would allow actual use of the header then.

Awesome, thanks to all.

I'm totally up in the air about a built engine or a swap later, hence my indecision. I was also thinking that the low end TQ loss would be more significant with the HO, especially since I'm not starting out w/ a high output engine in the first place.

I don't think I'll be seeing that for at *least* 2 years (unless I get absurdly lucky/significantly more wealthy =P), so it's probably best for me financially and efficiency-wise to go SS.
