Question Revolution Motorsports header info? anyone try em?

From what I understand this header is, for lack of a better word, a take off of the infamous Borla header. However it is my understanding a lot more care was taken with the welds and overall fit and finish of this header vs. the borla.

So, does anybody have any experience with these headers? I tried a search a few times but have come up with not much solid information to go on. (i also emailed Revolutions directly just a few minutes ago)

Thanks for your input

Joe

Ok, here's the deal (at least what I think)

First my car setup. Cobb CAI, stromung 2.25" midpipe, scoobysport axleback.

Installation was easy and straightforward, it took a little over an hour (including 15 minutes to find something suitable to use as a cheater / breaker bar, gotta love those titanium seatposts)

I had to push a little to get the header to line up with the studs on the engine, not too difficult. Everything lined up well with the exception of the support bracket for the cat section. It still fits onto the hook shaped support, but the bolt hole doesn't line up. I tried to move it into position, but it wouldn't budge so I figured that it'd be fine without the bolt.

Driving impressions:

I fired her up and was greeted with a nice deep boxer "Hello!!" which quickly settled down into a very quiet (I'd dare to say almost stock sounding) idle.

I immediately noticed a more responsive throtle and a smoother start. Probably due to some torque gains. The sound rocks, a nice spaced out boxer rumble that begins to sync up as the revs increase. Trailing throttle / compression braking sounds incredible I can't comment on WOT sound or feel yet, but so far I like it.

Apparently so did the guy getting into his lovely bright orange mustang. When I pulled into a parking lot his head snapped up and looked around, it took him a second to figure out that what he heard was coming from my little suby

I double BlkTS02's observations.... I just put the Rev headers on Friday.... they are great. And Blk said everything almost exactly as I would!

The bolt for the cat section just won't fit... I was a bit disappointed, but the support still does its job. You will have to "force" the header onto the header studs. It takes a little muscle to flex the header enough to fit it, but the fit is SUPERB... the holes line up perfectly (unlike Borla).

The sound is amazing.... I find myself tickling the throttle at red lights just to listen to the boxer sound... I have never heard my car sound like it does now.

Acceleration is MUCH smoother (I won't claim HP gains, but the cars is smoother). There is a noticable change especially in the upper RPMs.

Revolutions is a joy to deal with as well. If the header cracks (like Borlas do), they will ship you a new header with only a picture of the crack. Borla requires you take the header off and ship it back to them.... resulting in MUCH downtime.

Good header... great quality... and impossible to beat in the deal vs gains department.

well, i went with the borla as it was only like 260 shipped new. as for the sound of these headers, its great, the best sound yet. i have the stromug 2.25 SS cat back, and a cobb intake, and LW pully, the car is amazing now. as for fitment problems with borla, i had none, everything bolted up perfect with no forcing of anything, and that support bolt went on with out any problems.

btw: I got mine from a nasioc member who got them jet-hot coated, but never installed them. So $325 for brand new SS ceramic coated headers, I wasn't about to pass that one up

Blk: You need to look into the mechanical CEL fix... cost less than $5 from Autozone and is easily removed if you need to....

And a 0420 CEL does not affect your engine's operation I have had one for a loooong loooong time....

This header looks good, I wish they had these when I bought mine. The borla's are weak, I've had a crack in mine for a few months now and I have had them for about 8 months. I don't even wanna send back my borla's because then I'd have to wait. It would be cool if they offered you some sort of discount off if you sent them out your borlas. I would get the Cobb header but it's way to expensive.

Same Question

Plus....How would I go about getting a track pipe to remove the Cats...will a Muffler shop have the odd shaped flanges which go between the Cats and the midpipe? WIll they weld a bung into the new pipe for the O2 sensor?

When I read that I was thinking of another thread and a mil eliminator. Too many web windows open at once. Luckily it is somewhat relevant to the CEL issue with after market headers:
http://www.flat4engineering.com/main/index.htm

PDM O2 SENSOR EXTENSION

Extend the rear 02 sensor mounting location further from the center of the tube and out of the flow of exhaust gases allowing the ECU to see a change in the reading from the front 02 sensor to the rear 02 sensor.

Price: $19.95


I havn't tried it on my RS. But I did call them and asked them about it. They claim that it does indeed work on the RS for the P0420 cat ineff.. code. I am definitely going to try it if my last attempt at the resistor fix doesn't work.

So far I have tried the resistor fix 4 different times. Two different Cats, two different rear O2, and two different MIL eliminators from Ponyexpress performance.

I even called PEP and they told me that they really designed it to work on catless cars. Since I used it with both the stock cat and the new metallic high flow cat from Random tech, they tell me that the cat is working well enought that the computer is getting a signal it doesn't like, hence the P0136? "HO2S Circuit Bank1 sensor 2 " error. So all the resistor fix does for me is to change it form a P0420 to a P0136.

I think this mechanical fix is a much better idea. Since it doesn't modify the expensive rear O2 sensor it is much easier to undo if it doesn't work.

Even though my car hasn't thrown a code since the last time i redid the resistor fix (less than 200 miles) I am tempted to order this just to try it.

You would have to find a redneck shop or somewhere that is willing to do something "strictly for the race track" then you take it home and put it on full time yourself.

Or... you find a friend that can do a better job welding than almost anything you have seen and have him fab up a track pipe.... that is what I am working on.... waiting for stainless pipe to come on in.

The only header on there is listed as a "DC Sports" model. Is this the one being referred to as the "Revolutions Motorsports header"?

Hmm, that's the header for the WRX. If you're looking for the 2.5 version I'd contact them...

Update:

Had a rear cat. ineffeciency CEL. I tried the mechanical CEL fix, but I had to change the setup. The cat section sits pretty close to the underbody of the car. I couldn't use both parts from the HELP spark arrestor, so I only installed the one that I drilled out. So far so good, I'll keep everyone posted...

CEL is back, looks like I'll have to only partially drill out one of the parts so the 02 sensor doesn't bottom out.

Price is comparable to Borlas. Somewhere around $300.

BlkTS02,

Did you do buy those Help! parts listed in that thead? I think they are called Spark plug non-foulers. Any luck getting them to get rid of your CEL P0420?

Yeah, they're "spark plug arrestors"

What I did was to drill out one of them just enough so the 02 sensor threads in all the way without bottoming out, but still leaving the smaller diameter hole.

I installed the newly modified part last night, drove about 40 miles today both highway and city. So far so good

I drilled out the part by hand with a 1/2" bit, just be careful or use a drill press.
