I'm yet to test but still thinking as restriction goes, the less the better.
DIY Intake
Do I remove the Resonator - Not necessarily Warm Air, just no resonator, on the intake, or do I focus on the exhaust options:
Resonator Drums down excess noise.
Muffler (straight through) Enhances sound!
Hi-flow cat converter Better flow than standard.
Extractors Improves power & efficiency!
Stainless Steel Muffler For a distinct sound & style.
2.25 inch system Improves overall performance!
The engine is lean burn, so I don't want to interfere with that if it relies on exhaust pressure (not too sure how exactly it works in terms of lean burn - or if it is, I thought it was from Wikipedia).
Of the exhaust options, I'm not sure headers would be helpful, however, freeing up the exhaust flow might help ?
Low end power is where I want to focus.
Perhaps:
- Remove Resonator On Intake to reduce one point of restriction.
- After Cat Converter, go to 2in exhaust with a resonator to reduce exhaust noise..
Would that make a not so noisy daily driver with some improvement in fuel economy? (assuming the exhaust changes don't matter to the lean burn ?)
