2004 Civic DX Intake/exhaust/headers
Hello Gang,
My oldest son got a 2004 civic dx (automatic trans) for his 16th bday. He's had it about 7 months and now wants some "go faster" parts for his car. We ordered the following for him.
Spec D System Exhaust (stainless) with titanium blue tip
Stainless headers
Velocity Intake
My question is, will I need to get tuning done? If so who could you rec'd in the Chicagoland are OR is there a decent mail order tune I can get?
Thanks!

Re: 2004 Civic DX Intake/exhaust/headers
you could try but you most likely wouldn't see/notice any difference, car will just be louder

..If you purchased Ebay headers they are junk and will most likely crack within six months. Plus you may run into fitment issues. Engine swap or forced induction (turbo, supercharger) is the only way for power gains. Last edited by Wankenstein; 01-30-2018 at 11:40 AM.

If you think a good mechanic is expensive, try hiring a bad one

Loudness increases
Actual power/performance and fuel economy decreases

More like 1-5hp loss in the low end, no gain mid range, and a slight gain of 1-4hp at the top (>6000RPM; D17 has a 6800RPM redline and 7200RPM rev limit).
If you D17A2 head swap and crower stage 1 cam it, you'll see combined results. There's a dyno sheet floating around the internet of a D17A2 (stock, 127BHP/110WHP) basically recouping losses from the transmission (i.e. making ~127whp after intake/header/exhaust with a crower stage 1). Should also mention it was a gain across the RPM band, not just low/mid/high.

No need tune. ECU will not accept tune anyway.
1-5 HP if much.
Wait, does the header on DX like the LX? If so, it have a cat in it. If the new header don't have the cat, you better check your local emissions law.
It will be louder.
