BNR Down pipe installed.

[rdss]

Just installed the new down pipe from BNR. Install was straight forward, but, beware the hidden bolt for the factory down pipe hanger. Everything lined up perfectly and was swapped in in about 40 minutes. It looks and sounds great!

Here are some pics and a video in the garage.

BNR down pipe, idle and rev.

That clip was not NEARLY long enough.

The sound is perfect.

Thanks, here's a pair of 0-60'ish runs.

Thanks again! I cant wait to get a few more miles on if and a updated tune.

is there a good step-by-step install thread??

I dug through 10 pages of a search for "down pipe" and couldn't find a step by step.

1) Disconnect plug from O2 sensor.
2) Remove 3 nuts from mid pipe.
3) Remove 2 mount nuts, ones the infamous Hidden Bolt.
4) Loosen the v-band clamp until the bolt has come loose.
5) Remove Factory down pipe.
6) Go backwards from "5" up but with install/tighten instead of remove. You will use the factory gasket for the DP to mid pipe connection.

For the hidden bolt I found it best to unhook the charge pipe and get it from there.

Thanks. I got it in!

Here's a few pics that may help someone else:


O2 sensor plug attached to blue wire


O2 sensor (right) and v-band bolt peeking out from under heat shield. My O2 sensor was on petty tight


Three 13mm bolts at rear of downpipe. I found a nasty dent in the exhaust down there too.


Lower mount bolt, 10mm Hidden bolt, also 10mm, is directly above that one, facing the front of the car. Just kinda follow that mounting bracket upwards and you should feel it. I used an offset box wrench to loosen it and for the first few turns then I switched to a 1/4" drive socket wrench with a tilting head.

Good deal, pretty easy swap wasn't it?

 

[joshuarhorne]

does switching out the downpipe give a noticable change in performance?

Yeah. Not too bad.

does switching out the downpipe give a noticable change in performance?

Yeah. Feels like a little quicker spool and a bit more top end.

I think there was a dyno that showed 5-8 HP increase with a tune as well

i see if you pics you do not have the o2 installed. is there a reason for that or i am missing something.

 

[american_tuner]

Up high is the o2 sensor the one you are most likely looking at is the bung for the wideband

I was under the belief that you needed to remove turbo heat shield to install the downpipe....is the install possible without doing so? Because I ran into issues when trying to install because I did not have the correct size e torx socket to remove the shield. Any help is well appreciated as I am anxious to get this on to complete my exhaust!

I would be surprised if u install the dp WITH the heat shield on. It will just make things complicated. I don't know exactly the size of torx screw. But it should be in between 5mm-9mm.

I installed and removed my down pipes on multiple occasions without removing the heat shield.

Just use a regular socket that fits it. That's what I did and I even have 2 sets of inverted torx socket sets.
