I'm curious as to whether or not anyone from the US has tried RPW's 4-2-1 headers and if so how much did shipping cost you? Also, from what I understand the power gains would be greater than with the RRM headers (correct me if I'm wrong), but would it be substantial enough to justify having something shipped from Australia?

Dude, I understand we all want the best for our cars but just bolt ons like that you wont feel a difference between the two. Get the RPW if it will save you money.

 

Which did you end up picking? I haven't started my mods yet, and was going to go with RRM.

 

I ordered the RPW 4-2-1 Race Design Kit for my 2010 4B12. After the order, I received two emails saying they were back ordered. I emailed them, and had a good discussion with the owner/operator, Dave Thomas.

Me: Recently, I ordered a 4-2-1 race design kit for my 4b12 Mitsu Lancer. I've received emails informing me that the unit is back-ordered. Could you tell me when the unit will be available?

DT: We do not have an exact ETA at this stage. There are some units enroute from the supplier to us this moment, but we are still waiting for the shipping advice to arrive.

Me: Okay. Thanks. Do you have any 2.4L Lancer (4B12) headers available? 4-2-1 or 4-1?

DT: We only have some street design units in stock, we won't be getting any of our 4-1 into stock unitl Febuary next year.

Me: I think I'm looking for the street design. I've been reading through the 4B12 project you guys have, but I didn't see the Street design header on the product page. Do you have one available now?

DT: I don't recommend the street design for the 4B12 engines. Its really only suitable for the 4B10 / 4B11 engines due to its smaller diameter.

Me: Thanks for that! I'll have to wait. No problems. I'm going to replace the entire stock system. The project page you guys are working on details "Job 6," the 2.5" exhaust sys replacement. Are those going to be available, and, do you sell them as a complete system (header to exhaust tip)?

DT: We have the rear mufflers in stock, but we were not sure whether we were going to reorder the middle exhaust systems. We can order one in if you like.

Me: I'll pass. I'll wait for the extractor, and keep checking your site for some other items. Thanks for the service!

So, it looks like I'll be waiting a little until the 4-2-1 is available, then figuring out what exhaust system (aft of the header) I'll get.

Any ideas?

 

I thought DT owned Wendy's? lol Has the order shipped and were you able to test it out, or are you still in the waiting stage of things?

 

Supercircuit headers are far superior build quality to RRMs. RPW and Supercircuit are owned by the same company, but Supercircuit is the only one with a 2.4L 4-2-1 specific header.

 

I was looking at the rpw but decided to go with rrm just because they were closer for shipping and I liked their design better. Overall I'm happy with them they were a little pricey and the install was a pain. I didn't notice much of a sound difference like I thought I would, but overall I enjoy them.
