dc5r header (4-2-1) vs any race header
Truthfully it depends which aftermarket RH. Cause some of those cheap ebay knock offs I wouldn't use... I'd stick with ITR which has the R&D needed to support the engine.
But compare it to like a Hytech custom header and the ITR is blown away... I personally am a bigger fan of the long tube headers which trump factory. Plus the factory ITR still uses a cat so it'll never gain the power as a aftermarket full RH with no cat.

Oh nice info this the answer that im looking for,
yeah i figured the cat will still restrict the flow but it still has gains compare to stock/shorty ones but good brand rh still has better gains as you stated
thanks again bro
