baconbits Posted May 16, 2013 Share Posted May 16, 2013 Get a downpipe and an Accessport before you get a header. Link to comment Share on other sites More sharing options...

speedracer6 Posted May 17, 2013 Author Share Posted May 17, 2013 awww ok. That header ok for later though? Link to comment Share on other sites More sharing options...
fahr_side Posted May 17, 2013 Share Posted May 17, 2013 You won't gain much, if anything, using a header with the stock turbo. The turbo itself is far more restrictive than the header at this point. At this stage, about the only upside in going to a header would be going to an equal-length model and losing the blub-blub sound. Buy a downpipe and get tuned to stage 2.

Code Posted May 17, 2013 Share Posted May 17, 2013 When you need a quality header buy one from Moore Performance. "Striving to better, oft we mar what's well." - Bill Shakespeare - car modder Link to comment Share on other sites More sharing options...

baconbits Posted May 21, 2013 Share Posted May 21, 2013 Equal length = no rumble. Why buy a Subaru at that point? Link to comment Share on other sites More sharing options...
fahr_side Posted May 22, 2013 Share Posted May 22, 2013 Equal length = 20whp / 20wtq over UEL. Why buy a header if it doesn't get you that performance?

SpecBlitzed Posted May 22, 2013 Share Posted May 22, 2013 Buy a Subaru for the Rumble. Pshh. You can make any 4 cylinder sound like a boxser with an UL header Link to comment Share on other sites More sharing options...
baconbits Posted May 22, 2013 Share Posted May 22, 2013 Yeah, but you lose power along the way. Who pays to lose power? Link to comment Share on other sites More sharing options...

People who buy UEL headers for a Subaru, or worse yet buy an UEL header for a car that came EL as stock, that's who.

That's what I was getting at... Port/polish and a Grimmspeed crosspipe is about all I'd ever do. At stage 2 or 3 on a DD car, I'm never going to miss that 20hp. I should say, that 20hp sacrifice is worth having the rumble so I don't sound like every other EL header, 4 banger on the road. Link to comment Share on other sites More sharing options...
fahr_side Posted May 22, 2013 Share Posted May 22, 2013 Port/polish and a Grimmspeed crosspipe is completely pointless, with gains that cannot separated from sampling noise. Fixed.

Nrw Posted May 22, 2013 Share Posted May 22, 2013 I still haven't heard a boxer with a ELH that sounds like an inline 4 in person :shrug: ELH or stay stock. The invidia 1.5scroll is a lovely piece. Similar to the full race piece. Link to comment Share on other sites More sharing options...

wonderbread Posted November 14, 2013 Share Posted November 14, 2013 Thread's not QUITE dead yet, right? Still 2013 lol Everyone has addressed the performance gains, but none the reliability gains. Having an ELH means your engine's exhaust pulses aren't fighting for space in the pipes, in fact they'll draw eachother out through exhaust scavenging. Biggest problem with any turbocharged Subaru: cyl 2 & 4 running hot = cracked ringlands. I just bought Invidia ELH to prolong the life of my stage 3. The hp & tq are just a nice side effect.

wonderbread Posted November 14, 2013 Share Posted November 14, 2013 And I really like that Killer B made a 4:1. I think that's the only 4:1 on the market. A little bit better than 4:2:1 for high RPM I believe? Link to comment Share on other sites More sharing options...
