I'm curious to see other dyno test with these headers.. Seems like awesome gains, if I could get more than 5hp/tq with these, then it seems like these are the shortys to get.

I'd love to see them too. I believe at this moment I have the only set. I could be wrong, but I think this is the first production batch.

Next month I will be getting an intake (Injen unless Vararam comes through). If I can find someone in OC who'll give me dyno time at a good price, I would love to run it again for comparison. So if there's anyone who reads this who knows a place to get a dyno done in OC, let me know.

Yep ~ 5rwhp and 8lb-ft of torque.

Never ran them with the tune, so no idea what they would have produced. I'd guess another 2-3 rwhp and 2-3lb-ft of torque.

Yes they did! Definitely a nice aggressive note!




All that said, I'm not for sure the DTs will make much more power then the JBAs did. Those numbers look really, really good though, and I hope they are accurate. Of course, like scrming hinted at, different dynos, different results, lol.

Okay, I promised I'd report on the sound/power changes.

Both are noticeable improvements. The sound is dramatically different. I've put 7000 miles on the car with just the DT Catback, so I know how this car sounds. The headers really changed things. It's actually quieter at cruising speeds and the rasp I would sometimes get around 4500 rpm is basically gone. I would describe the sound as smooth.

It's not boomy or intrusive in the cabin, but it roars when you step on it. I made a little video that gives a sense of it. If anyone knows how to embed this, please do:



As for the power, there is a difference. The dyno shows about a 8-14% gain in torque. I'd say that's about what if feels like. 10% isn't overwhelming but it is noticeable. If I had a Dashawk, I suspect I'd have dropped at least a 10th of my 0-60 time.

I did do a run on the on-ramp from 0-70. Usually when I punch it, the tires chirp a bit before they catch. This time, I heard them rotate on the pavement. It sounded like pulling a single sheet of paper out of a pack and the car slid over a bit before it caught pavement.

So, the sound is fantastic (to my ears). The power increase is there. I wish I could confirm it on the track, but the nearest one is an hour away. Hopefully I'll be able to afford another dyno run after I get my intake replaced.

Great video, thanks! It sounds really good. Do you have any pics of the headers?
