1 left in house ALL

 

We have SOLD OUT of the Garage Line Header

They should be back in house in 2 weeks. PM me so you can be the first of the lot to get yours when they come in!!!

 

Was wondering. How long should it take for a muffler shop with a lift, to install this header?

 

It takes about an hour start to finish..you have to remove passenger side motor mount and loosen the drivers side top bolt....push the motor over...n then it's fairly straight forward re/re of the manifold....as long as you get the O2 sensor out easily

 

Only an hour? I'm getting install quotes from some local shops stating 3-4 hours minimum at around $350-$380+ which doesn't make any sense.

 

Im far from superman and it didnt take me that long....2 if they don't know what they are doing cause it is the first time

 

Uh, 1 hour?

No way, unless you have some secret method. I just discovered it won't go in without also removing the midpipe - though maybe I can shove it back enough. Otherwise the two crossbraces and rear O2 sensor gotta come off too. This header is much "fluffier" than the manifold so it won't go in through the same gap that the manifold came out of. The Racing Beat instructions don't refer to that step, so perhaps their's is more compact. Of course working without a lift makes things slower and more difficult. Right now, $300 for an install sounds like a bargain.

 

^ I think the aprox. 1 hour install is using a lift and I believe he's done it before. I contacted RB and they also said 1-2 hours on a lift. If you look at the RB header pics here and here, it looks even more 'fluffier' less compact, as the center and end pipes seem to extend outwards, way more than the garageline.

Were you able to install yours?

 

Yes, finally. The Law of Unintended Consequences kept me from raising the engine enough, which I think, caused problems. I'm running the Mazmart oil pressure mod, which means there's a taller Series II filter on top of a Prosport adapter. This blocked the engine against the firewall when lifted.

However, the rear header mount doesn't fit well, see pic. Either the angle, some weld goop, threads, or something kept the stock bolt from threading into the nut properly. I had to use a 5/16-18 bolt to fit through the nut. It's not a show-stopper, but is annoying.

 

^ How long did it take you to do the install? Also, do you feel any difference in power (and is it louder)?

 

I'll take the Fifth on the first question. It took me at least two hours to jack up all four corners of the car, put them on jackstands, and figure out how and with what to lift the engine. The front, middle and rear crossbraces have to come off to be able to get the midpipe out of the way. Etc.

It won't be running for another few days until other work is finished.

 

lol wut, why did it take you 2 hours to lift the car to jack stands?

its like 3 minutes a corner for me, then I use a 14 in long 2x4 to lift the motor with the same jack that i lifted the car with.

Motor mounts loosened within 30 minutes and motor up in another 5.

You can get the bottom cross members off in about 15 minutes.

Then you can remove the stock header.

I would say 2 hours and you should be good.

Note* I use impact tools

 

Agreed, however it took me a bit longer.

I had problems with the motor mount, that bitch was on there tight!

I also had a manifold bolt strip the housing threads on the way out.
Thanks god I own a tap and die set

edit ----=
I'm also slower due to beerrrzzzzz

 

Good for you. I do not wish to engage in a contest of "who's THE MAN". I do not have impact tools. I do not have optimal equipment, like appropriate hydraulic jacks. To do one corner, stock scissors jack up, jackstand, jack down, 2x6 underneath, jack up, jackstand, more 2x6 underneath, jack up, jackstand. Etc. I do not have a dedicated car shop (tools have to be retrieved from the basement), nor have I done this job before (though I have done many others). Finally, I make no claims about being fast, but I suspect most hobbiest first-timers to this job won't complete it in 2 hours.

YMMV.

 

I wasn't trying to say I am "The man"... I was just curious why it took you 2 hours to lift the car up to stands. Makes sense now, scissor jack is not optimal to use.

I was merely justifying the 2 hour estimated install time.

 

Okay! A pro or pro/am is most always gonna be much faster.

 

Just had the dealer install mine a few hours ago, and it took them 1.5 hours. Of all places, they were by far the cheapest.

With this header installed there is some noticeable power above 4500 RPM, and is a lot louder in the high RPM's as well. It also seems to backfire more often too. (I have a full TXS exhaust with race pipe with MM tune)

I also notice there is a slight burning type smell inside the cabin (as noted in the RB instructions), but hopefully it will dissipate after a few drive cycles.

 

+1. Perhaps I should note that the header comes with bolts, instead of studs, for the connection to the air pump pipe. On the front one, the bolt is too long to press on the flange - I had to use a shorter one to get it to seal.

 

If you are running a full exhaust including header and no cat, then why continue to run the air pump? Cap that bung off and remove that ugly pump from your engine bay

 

'Cause I am running a cat (high-flow, metal substrate). I'd rather smell my date's perfume, etc, than stinky rotary exhaust.

 

I see.


Your going to blow through that pretty quickly with your new headers.

 

Maybe. I've got 10k miles or so on this cat, still no CEL and it looks brand new inside - so far. Magnaflow #59959. I also have an EGT probe mounted right in front to monitor temps going into it. Will see if that changes significantly with the header. I suspect the temps will be lower due to increased heat loss compared to the manifold.

 

Just to update.

There is a slight hiss noise or 'sssss' coming from the header when you accelerate. I also had noticed this 'hiss' noise when I had a header installed in my previous car. A quick google search tells me it's normal with an aftermarket header - due to it not having a heat shield and thinner walls in the runners.

The loud drone noise when cruising at highway speeds is now noticeably quieter.

Also that 'burning smell' when the header was first installed, is now gone.

 

I'm not hearing any hiss at all, in spite of having no firewall insulation. You sure there's no leak? If they didn't use a short bolt as described in post #118, then there could be an exhaust leak where the air injection pipe connects.

 

ALL we got 2 in house. We had a lot of 10 and due to ALL the pre orders they have been spoken for and shipped out. WE HAVE 2 LEFT!!!!!!!!!!!!!!!!!!!

Complete your RX8-CBE and unleash the amazing sound that is hiding in your car :D!!!!!!!!!!!!!

$250+ shipping!! Shipping isnt that bad ALL.
