Are DC sports headers any good? Thread starter wreckr Start date Jul 3, I want a smog legal header. Are they reliable? Do they improve HP? Gas mileage? Registered OG. They will make your car louder and seem faster but they actually will make it slower.

Theyre pretty good fir the price. They have a decent reputation, for a long time they were kind of the standard but in my opinion they kind of suck. I've had 2 and they both cracked. They used to be their own company, then were owned by AEM. Now I think they are owned by Pilot, makers of lots of shitty AutoZone parts. Very I-love-thes if you ask us.

Not only that, but our engine bay needed some shine since the rust-look of the OEM header without its heatshields was looking a little bland; the DC header solved that problem and also had no fitment problems with regards to the front crossmember.

Those who opt for the design may encounter fitment issues. Of course, we needed to see how much power we'd actually gained by adding a header and a slightly more free-flowing exhaust, so we stopped by SP Engineering to find out since they have our baseline figures on file.

In its stock form with the HKS Sport exhaust , our car originally made With three new passes, we came out on top with an extra 4 hp, translating to The gains weren't astronomical but as to be expected, considering the car still has a stock intake. Once we get the car smog compliant, we'll be able to put an aftermarket intake system in and should see bigger improvements. For now, the DC header was a great buy and the Mugen exhaust, simply a cool piece to add on.
