Hey Guys,
Check out these from a post on the Aussie site ClubCJ.net where I am a member---

Also this new stainless steel exhaust system----

What do you guys think of these compared to components from US suppliers???
Some people here in Aust have had problems with RRM headers,... flex pipes failing etc.
I would kinda prefer to buy from here in Aust if possible but want to get a high quality product at a good price.
I already have an aftermarket axle back muffler but am thinking of possibly getting headers (Race design) and centre exhaust piping.

 

nice but 500 bucks for a header? ill pass on that one. what kind of gains were they expecting?

 

Nice pieces! They are a bit pricey, but look to be pretty good quality.

Would love to see the gains on a 4b12 with the midpipe and headers (extractors).

 

sweet! send me 1 4-1 race header and the full exhaust for free so I can test it for you guys!

 

would this work with pzev

 

i think so, it would just remove ur first cat....yo uwould have to get an O2 bung welded in for that O2 sensor and you will throw a CEL

 

i just installed a version 1 header from rrm & its fitment sucked to put it nicely! the gains were very nice with it being ceramic coated, header wrapped & silicone sealed!
but rrm products have been disappointing lately
RPW on the other hand looks to be coming out with some real nice parts lately really like their headers & the reflash is a deff must for the price. tactrix 2.0, openecu & 70$ definition file and you get more hp than any bolt on at half the price
looking good so far, just need a vid of that flash at work.

 

Hey Guys,
Thanks for all your comments.
RPW website prices are in Aust dollars and for international customers those are the prices plus shipping costs.
Here in Aust we have to add the 10% GST (Goods and Services Tax) to those prices which goes to the Govt on the part and shipping. ..... so you are getting the parts themselves cheaper than us Aussies by 10% plus the approx 14% advantage in the exchange.

Exchange rate still favours the US buyer as usual, and was about 1USD buys 1.14AUD yesterday. Of course that rate is controlled by the banks on the day of transaction.

They will be doing dyno testing on the new headers very soon and the complete exhaust system being offered and will post all the results and Stage 2 ECU flash testing ASAP no doubt as they are keen to start selling them ASAP.

They have already posted Dyno results here from some earlier testing with different parts, intakes and exhausts on CJs.
Have a careful read and a look thru them. The Run ID description boxes explain the configurations used for the before and after run. I was told the runs are done in 4th gear and the ups and downs are caused by the variable cam timing, David has explained everything.

Details re the Dyno from that page--

"All Dyno tuning will be performed on the Dyna Pack Hub Dyno. The reason being that this eliminates any variations in tyre slippage, heat in tyres etc. This is a mechanical hub connection to the wheels and whilst the numbers may be slightly higher over a normal roller dyno, the gains are 100% confirmed between runs with no variations to worry about other than mild tempature variations which we will be attempting to minimise.

For a link on this click here ----> http://www.dynapack.com/dynapack.html or the USA Site http://www.dynapackusa.com/testimonials.htm. Pay particular attention to the Testimonial from Apexi - I think this covers everything we woudl ever need to say about this choice of dyno.

Final point - please note that even though our dyno graphs show the readings as Flywheel Horsepower / Flywheel Torque figures, the calibration option is set to a Factor of 1, which means that hub and flywheel horsepower ratings are identical. Hopefully this will clear up some confusion people have with the results from the dyno print outs."

I am looking forward to seeing the results.

Not really cheap. 800 bucks for the mid pipe then another 400 bucks for the exhaust outlet. That's 1200 plus shipping for an exhaust. Woo. No thanks.

 

what about kooks, or kooks exhaust are they any good?

 

looks nice, i would like to get it. just wayy too expensive for my tastes.

 

what are the gains for this? need to compare it to the only other one on the market
