JB4 + ??? DP's

[Seattle135is]

Definitely doing the JB4 - on the fence on which DP's to go with - I'm on the Group buy for the Canadian Haute DP's, but this is taking time - so, my choices are Akra and Eisenman - which would make the OEM exhaust/Turbos pop more? Or is there another option I'm not considering?

There are a lot of DP options you just listed the most expensive brands. If you are going catless one is not going to be better than another IMO. Just get the cheapest one with good known fitment. I've been running Evolution racing DPs for over 3k miles with no issues. There was a poll thread on the forums and they were the most popular from a price value perspective.

Honestly they are all relatively the same due to the fact that there is little room to really make any dramatic changes to the piping. The largest downpipes are 3" in diameter which allows for the most air flow. My personal suggestion is to just go with Status Gruppe or Evolution Racewerks. Both are 3" in diameter and made of T304 US Steel

We are currently running the ER downpipes on both our shop cars.

Definitely get the downpipes. They go so well together with the JB4. Evolution Racewerks Downpipes are pretty popular. We have had them on our car. We also fitted the ar design pipes and those are a great fit and finish as well.

Hands down Evolution Raceweks. Never had an issue with their products on any of my cars.

Let me know how you like them once you receive them. I think both are in route to your shop now

Thanks Mike - they are being delivered today - install set up for Wednesday, which is also my birthday - it's gonna be one kick azz present to myself!
I drove a buddy's M4 with the same combo on Saturday - it's a frikkin animal - I'm already thinking of going wider with the rear rubber.
I tried searching and found sporadic dyno results - do you have any links with results of different maps on the JB4/DP's?
Thanks for the awesome and hassle-free service!
