Has anyone mounted the street header to an automatic yet?

Postby Fat Broke » Fri Oct 19, 2012 9:21 am

I have an '06 soft top (street car) that I will run a RHT for a few months a year. This with the mid-pipe seems to be the right set (if I want the spousal unit to come with).

I haven't seen a definative post stating it has been done. I did read about the performance header and grinding a bracket to fit (sounded fairly easy).

What say you? Anyone done it?

We have sent just one of the new RoadsterSport Street Headers to customer with auto and he has not started his install yet.

I too am interested in the results of the automatic install. Bought a 2012 automatic back in March (wife absolutely refuses to learn a manual. I don't know, something about a bad childhood experience). Am wanting to do the same mods as the 2012 project car over the Minnesota winter. Will be following to hear the results as soon as they appear.

Any currently known reason why the automatic wouldn't hold up well under the increased horsepower, assuming a spirited driving style?

Our Roadstersport Max power header has been used on the automatic for many years. The automatic hold up fine...

It has more to do with the increase in underhood temps and the lines for the transmission cooler. I've used the race header on an auto for 3+ years and 35K miles. The cooler lines come with heatshields on them and the header sits close enough for them to rattle against it. I'd try and find a way to shield the street header if I were to use one, the catalyst is going to generate a lot of heat and put it right next to the transmission cooler lines.

@JamesM... I bit the bullet and ordered the max performance header, did you find a way to eliminate the rattle?

I removed parts of the heat shields that were on the lines themselves. It wasn't a really loud noise, just what you'd imagine a couple pieces of tin-like material touching the header would sound.
I'll probably be changing the header soon, so I'm going to look into it more when I get everything apart.

Brian, have you had any feedback from the customer with an automatic who ordered the street header? Also, would the Roadstersport Max power header be any easier of an install on an automatic than the catted street header? Curious since you said its been used on automatics historically. Wondering if not having the cat down there brings in less issues with fitment and the heat on the cooler lines.

In Nic Grossi's automatic notes for the header install instructions he talks about grinding down the ear on the bracket that's used to route the clutch cable in manuals, to make the header fit on an automatic. Doesn't sound too tough with a vise and grinder. Do you know if he ever did post any pictures anywhere? Still leaves the cooler line re-route or shielding issue.

Would love to use the ceramic street header on our 2012 PRHT, but looking to sort out all the considerations of the best route for an automatic first. Thanks!

JamesM - Thanks for your post(s). So after removing the heat shields from the lines themselves, heat wasn't an issue with the race header?

Looks like the street header will not fit the automatic without a fair bit of work. So, we updated the product description to suggest professional install only.

As for RoadsterSport Max Power Header on the automatic, folks have been doing that for years, no need to grind anything (the bracket Nic talks about can just be unbolted and removed, really not clear to me why anybody would bother to grind the bracket).

I have the performance header and midpipe on the auto. The midpipe does contact a bracket on the transmission , it looks like I could grind down a section of the bracket and gain 3/16" clearance or so. It would rattle occasionally, for now I have attached 4 layers of soft aviation grade heat shielding between the cat and bracket, I didn't want to damage the cat. I will drop it and see what can be done this winter.

If we are talking about the same bracket on the trans, it can be unbolted. Some have chosen to grind it, we just remove it.

The RoadsterSport Max Power header installs on the Automatic usually with no issues other than doing something with that bracket as mentioned above.... but sorry to say the RoadsterSport Street Header is a real close call with both the bell housing on the automatic and the cooling lines. I will post some pics from a customer who had the Street Header professionally installed and the installer made his own cooling lines to relocate them.

Thanks for the pictures Brian. That really helps make all the explanations more clear without pulling things off the car. Since we don't have emissions tests in Minnesota I'll be going with the Max Power header / Mid / Q package then for a late Christmas present. Street header sounded good in case we ever move, but a better fit and a little more hp and torque while I'm at it sounds best. Then all I'll need is spring! Happy Holidays.

Just installed the silver ceramic coated RS Max Power header, mid-pipe, and Q on our 2012 automatic. The one issue is the small spot on the transmission cooling lines where, after torquing down the header bolts, one of the tubes touched the factory heat shield around the transmission cooling line. So what I did was to wrap that short space of the cooling lines in one additional layer of heat tape on top of the factory heat shielding (like I used on the rest of the uninsulated portion of the lines ahead of that).

Of course the downside of that is that it adds a little more thickness so the header tube how meets it with that much more contact. What I'm afraid of is that I may have inadvertently created a fire hazard. But I don't know how hot the bottom of the ceramic coated header gets. I just know its cooler than stainless. Would the ceramic version get hot enough there to ignite the heat tape?

Does anyone know if the lines can be moved in just a little by removing the frame bracked just ahead where they go into the transmission, and then just slightly loosening the connections into the transmission, and not loose (much) fluid?

The thermal tapes can be right in contact with even the uncoated version of the header and they won't ignite, the stainless does a fair bit better job of keeping the heat inside than traditional mild steel headers and with the ceramic the result is even better.

Thanks for the quick response Brian! That's a relief. Think I'll spend some time with it as is then and see how well things weather. I absolutely love the result that I ended up with here. Ceramic silver is beautiful and it all sounds great in the garage. Soon as the (expletive deleted) snow melts looking forward to road time. On to the suspension in the mean time...
