Hey guys I threw a bearing at 10k on a TSM built motor (money shift!). I have it at AllPro Subaru now getting a new shortblock. I am looking to go EWG and swap back to Unequal headers (typo in title). I've got a 2013 STi. Looking for new or used parts. Looking for: External Wastegate up-pipe Wastegate Unequal Length Headers E-85 fuel pump > 400Lph Fuel Injectors >= 1300cc Fuel Rails
ELH, faster spool, better flow, different sound. I want an ELH on my car for power reasons, just my opinion. If you were to trade for a factory header... how much money would you want on top to make the trade, if interested?
Definitely not going factory. Pretty sure though that UEL headers are known for quicker spool. Agreed on overall power being greater due to aligned exhaust pulses creating better mid and high range power.
