I just installed this exhaust today; mine has a "XS Power" logo plate welded on it. I do not have any pics yet, but should by Wednesday. I'd be glad to put this all into a how-to w/ pics if anyone wants. I only drove it a bit after installing(idle, cruise & WOT), but I never threw a CEL and didn't have any over-boost or spiking. I love that it has an extra bung for a wideband sensor or such.
Ebay one I bought
It fit perfect for me. The turbo flange matched right up and all those bolts/nuts went on fine. The flex section made mating the dp/mid-pipe a breeze. The muffler went on the same, no troubles. I thought the hangers would pose a problem with this exhaust, but they all lined up fine. The only part I don't like, is how close the muffler is to the bumper. I'm hoping some Kartboy long rubber hangers will cure the problem.
While they aren't the best welds in the world, they are still good welds. The stainless steel looks great, only time will tell if a good, quality SS was used. Hangers were welded good & in the right places.
Stock Removal ::
Removing the stock exhaust wasn't bad. I had a few bolts/nuts to break loose, but just used some pb-blaster & lots of muscle. With the car jacked up, the stock dp will come out from underneath without having to remove the second part of the dp. The O2 sensor was a bit of a pain without the right tool, but it still came out with a little muscle. Go rent/buy the O2 tool, it is worth it! I'd also recommend a couple cut up 2x4's or something like it to hold up parts of the exhaust if you are working alone.
I've heard the vid clips on here and it is right on par. At warmed up idle, it has a very nice low, deep rumble. The minute you get over 1500 rpms, it does get a bit loud. I was hoping for a tad bit quieter, but it is what it is. There is no raspy-annoying sound, just deep & loud at WOT. I have not put in the silencer to test it out. I hate the look of the silencer, but I will test it to review. I think I just got so used to the stock, whisper-quiet exhaust and this one will take a bit to get used to.
It is a night & day difference in hearing the turbo. The spool up sound is very noticeable now, which is a plus to me. Who needs a bov when you have the sweet sound of compressor spool!
Hope this helps & sorry it was a long read,
EDIT :: I did not install the up-pipe, so no review on that one.
