Nice gains for just having a stock downpipe. These X's really seem to lose that super low end torque with bigger turbos, but I bet you gain a bunch back with downpipe/O2 housing/tune. I'll need a ride in this thing on the fall cruise since I never did get one last spring Mr Flips McGee :D

Another piece to the puzzle. I spent a few hours swapping in a MAP o2 elim downpipe last night while spaz was doing his brakes. We got sidetracked a few times due to stuck brake pad pins but we were mostly done by my anna-imposed 11pm curfew (gotta get up early for work and the pups go crazy every time I come in for keys, wash hands, etc etc), we had to go till about midnight to finish everything up but she was pretty understanding due to the fact that she was swooning over how beautiful this piece is:

Tennis ball rolls all the way through this thing no prob (I was curious about the flex section):

Next to the stock 'o2' housing and downpipe:

This thing is big, getting it in place was not hard but unfortunately I did scratch the ceramic coating just a bit on some of the heat shields on the firewall :( Without the flash it's tough to see, but there it is, gah! When you look down at this thing from the top it is kinda impressive how BIG it is. Fitment was absolutely perfect.

Fired it up for a leak test and around the block quick before bed, the first real test drive was on the way into work this morning. I drove Anna (like most days) and kept it pretty mild until I dropped her off. Most noticable improvement is part throttle in the 2500-4500rpm range, the car feels fantastic! The BBX felt a teensy bit doggy on the stock o2/downpipe but I have done nearly zero tuning to really try and get it more responsive because I knew this downpipe was on the way sooner rather than later :)

I threw on the logger and did some more aggressive driving and 3rd gear WOT pulls after I dropped the lady off and WOW seat of the pants feels great! Butt dyno immediately said 15whp up top, so after playing around a bit I went to one of my usual straight, flat spots and did some dedicated VDR pulls.

Always remember to take these with a grain of salt, it's not a true dyno but as best of a back-to-back as I could do!

The low-end makes no sense to me, its obvious that some tuning is needed from my tweaked stock turbo tune so I'll be addressing that in the future, but holly balls! +25whp@7000rpm! I am extremely happy with this thing and would recommend it to anyone. The fit/finish/quality is just top notch.

Next week the car will be at DB :)

That DP looks really nice actually. GG MAP

Looks great, I think those pictures alone have swayed me a bit in favor of the MAP unit over the AMS.

It definitely looks snazzy when coated. If it'd been out a year ago then I would have went with it.

[Murlo26]

If I go to an external dump I will do a MAP one I think, I still am very much in doubt on the whole one downpipe vs another arguments, don't know who to believe.

The MAP one for sure looks good though, support our local shop :)

I see that they included lock washers as well. To this day I don't know why Specialty X didn't do that on my system, would have saved me some lost bolts.

I think they are both good DP's, you really dont lose no matter which way you go. I went the AMS route for 3 reasons. 1. The MAP DP wasnt out yet. 2. The AMS cast piece is so huge, you can literally put you arm in it all the way up to the elbow. 3. Cast piece should last forever, and I dont wanna ever have to take it out. Ask Schiedes how may band aids were required for install.

:lol:

That is one sexy pipings.

Damn you X guys are whiners! It did take about 3 hours but I was taking my time, and the worst cut I got was working on spaz' car :D Having the right tools is absolutely key though, I bought this 14mm swivel socket and it is now an absolute must for any X owner IMHO. It gets right to all those stupid hard-to-reach bolts on the back of the motor.
