MAP got the downpipe to me very quickly and the quality of construction was beautiful. I opted to get it from them uncoated so I could try out a local coater here in the Dallas-area. All the welds are so smooth and gorgeous! One thing I'll note that you can't see in the picture is how smooth the flex is internally; it definitely will not cause any restriction or turbulence to the exhaust flow.

As it arrived - bare stainless:










After ceramic coating:








Install/installed:








Fitment:
Overall fitment was perfect and spot-on with plenty of clearance throughout. The only thing though, the o2 sensor bung location is very stupid. Rather than retaining the stock 12 o'clock orientation they opted to angle it towards the passenger side of the car which results it in rattle on the chassis at idle. I do plan to talk to them about this so hopefully this will be changed for future batches. They should also include and extra bolt/nut to replace the one stud utilized on the stock o2 housing. Luckily Cobb had plenty of hardware in stock so it wasn't an issue.

Results:
I discussed the piece with Cobb Tuning - Plano and decided if would be best if we fully retuned the car, installed the pipe, then retuned the car again all in the same day to make sure we got valid back-to-back results. Thanks again goes out to help for facilitating all this!





As you can see above, it provided SOLID GAINS throughout the entire powerband. 9whp & 5wtq with the stock turbo on pump gas!

Great review as always... Kraka *** moderator...

BTW was that swain tech coating or something else... it looks nice

I honestly don't know what it's called, but it is definitely not Swain Tech. I told the coater above all else I wanted the most durable coating he has to offer. He said this is durable enough to use metal polish on plus it has the best thermal barrier properties. I'm pretty sure is the same/similar to the coating Buschur uses on his ported exhaust manifolds. I had one on my IX and it held up perfectly even after 50k miles/3 years.

I'll also add that the o2/downpipe threw the tune off quite a bit; same report I got from a friend who installed the AMS widemouth. I definitely do not recommend anyone install this without proper a logging setup and/or access to a dyno.

Reasons why I opted for the MAP vs. the AMS (the main two I considered)
1. Divorced wastegate design
2. Price
3. Weight

I feel the divorced wastegate design will provide more top-end flow since rather than having a huge bellmouth it smoothly merges the wastegate and turbine gasses back together downstream away from the turbo outlet.

weight comparison
stock o2/downpipe: 14.8 lbs.
MAP o2 elim dp: 8.2 lbs.

Great looking piece Kracka. I have the o2 eliminator w/ open dump for my VIII and it's one of the best parts I've bought to date.

Great review sir, I'm liking the gains from 4500-6000 on stock turbo and pump gas

Looks like a fairly nice piece

I am looking to get something asap for my car.

Any chance that it can be made:
a) without the flex part?
b) with a better angle on the stock NB port?
c) adding a WB port

Will it fit RHD? AMS widemouth does not!

Who did you go through for the ceramic coating? It looks very nice! Is that something MAP offers or you had done yourself?

iTrader: (14)

why do you want it without the flex?

tephra

iTrader: (6)

Thats not a MAP coating. Kracka will have to tell us who did it!

Although they do offer the service...

tephra

iTrader: (6)

because I am a firm believer that it will be the first part to die...

the stock exhaust doesn't have one, so I am not sure why this would..

and a donut gasket isn't that same thing

I've discussed the o2 sensor bung placement with MAP and they have revised the location for all future pipes so that's a definite good thing. They also offer an optional 2nd bung for a wideband. Hopefully they can chime in tomorrow morning regarding the flex and RHD fitment!
MAP does offer ceramic coating, but I wanted to try a little local shop here in Dallas, TX. MAP offers a black or blue ceramic heat coating which I believe is rated to 2000F.

I relocated the front o2 sensor today to the the testpipe, it's about 6" further downstream than stock so I'm not worried about it throwing off the readings. For the rest of you guys, MAP will be correcting this on all future downpipes.

So has MAP corrected this problem? Looking to get one soon.
