Big Thanks to Danny Tran (www.DTRfab.com) for a great product, very fast production and helping me modify my carsound and b pipe for proper fitment.

This is my 5th header on the R. Previous ones were Usdm itr, DC Jdm 4-1, Jdm 4-1, the last one was a compact Anr 4-1.

My header of choice before DTR's header is the JDM 4-1.

Here are some pics of my new header.

 

Is it just me, or does that look exactly like an SMS Header?

 

cute kid

 

i was just thinking. wouldnt it be more beneficial for the o2 bung be relocated closer to the middle of the flange where it conncects to your cat/testpipe?

Yeah that's going to be hard to get at. They should have put it on the side like this:

Since I run Obd-1, I only use the front o2 sensor, but the o2 bung is pretty close to stock location, mine doesnt have any trouble being connected.

 

now that makes perfect sense

 

That header looks so money. Has it been installed yet? Review?

 

sweet...how much did it set you back?

Its installed, just havent driven it out yet. I hope to get a baseline dyno with it tomorrow if the shop would hook one up.

As far as costs, lets say I don't normally have this amount to spend on parts for the car, this was a one time shot so I decided to try out one of the 'best headers' out there.

 

haha, with that header, there wont be a 6th header. to DTR

 

Simply amazing work. That's who I was going to have build my header until i decided to go turbo. DTR

 

Can't wait to hear what you think, keep us updated.

 

nice looks like mine.

i just asked danny to make me a testpipe to fit my stock exhaust. car pulls even harder with no exhaust noise

 

So out of the previous headers, you liked the JDM 4-1 the best? What was wrong with the AN-R 4-1 design?

After reading and viewing similar set ups with headers with equal length and stepped primaries, I decided to give it a try (Hytech,SMS, DTR). After seeing some of the Anr graphs with similar set ups (locally) it puts out as much power as a Jdm 4-1(this was on a couple of different cars). I've asked a few people (who have tuned cars using the ANR header) and they have said that the Anr 4-1 is equal length, but is either just as long or shorter than the Jdm 4-1. What I noticed with the graphs I have seen with the Anr, it loses power compared to the Jdm 4-1/DC Jdm in the midrange (6-7.5k) while peak remains very close (1-3 whp) +/-.

Not saying there is anything wrong with the Anr header, I just rested my decision to get a header that has been tested and dyno'd making power with a similar set up as mine. When I got the Anr, there were no graphs or anything proving anything, I bought it soley because a couple of 'popular' racers used a similar design (Bisi, Ericks).

I really hope to get a baseline tomorrow for no charge, I'd like to post it for you guys with my set up description.

Keep us posted.

 

simply sick looking.. once again danny makes a beaty header and 1 more happy customer!

 

How is the ground clearance on the header?

nah, the SMS has a flexy thingn' in the rear

 

So why have you gone through so many headers?

 

Nice header. That's so money.

Btw the DC and the jdm 4-1, was there really a difference in ground clearance? I've had both but not at the same time nor car, so I couldn't really tell. I hear that the DC hang lower but never actually received measurements nor pics.
