Experience with this x pipe?

http://www.ebay.com/itm/390877591341



Seems like a well made item at a reasonable price. Anybody has experience with this, in terms of quality and performance. Most notably, a pair of resonators are essentially at the same location as the primary cats up stream. Most the quad resonated x pipes I've seen so far have resonators down stream around the "X" cross section. Do up stream resonators reduce noise more effectively and/or sacrifice power?

Looks like the TopSpeed x-pipe with resonators and cats. When it first came out, it had neither, but cost only $475 shipped. I bought one and it was too loud -- as any uncatted/unmuffled/unresonated x-pipe would be for a daily driver, so I added 4 resonators in the Dinan/Borla style. Had mine for 3 years now and it is fine.

The blasphemy....

Topspeed was heavily criticized in the 350Z realm for the lack of material quality. Outside of that, though, the top speed test pipes were pretty popular once their quality control issues were addressed.

In general, I'd avoid non-cosmetic products sold on eBay for our cars.. Just cause u don't REALLY know where the product is coming from Loll.

Why's that? I'm asking out of curiosity, not to be a dick

If the claims are true about the T304 stainless and the TIG welds are clean, why not save a few hundred?

I personally haven't had any horror stories but Iv heard from others about exhausts suddenly cracking or electronic parts blowing out fuses, etc. I purchased carbon fiber grills from a vendor here whose products come from China and one of them after 2 years has faded and turned a nasty shade of green..

But I'll admit I personally haven't dealt with this brand so I could be wrong and this might actually be a steal haha.

Well, let's look at the facts. It's T304 stainless and TIG welded (I'm assuming by hand). If the welds are true and the stainless is actual T304, what makes it different than any other X pipe (built to the same specification).

I'd be more worried about fitment and placement of the O2 bungs, but that's more on the production process than the choice of materials, IMO.

I'm not advocating one part or the other, just throwing out some points to open up more options for X pipe purchases.

I didn't like this X Pipe when I ran it, I sold it later down the road and got a Gintani X pipe. OP I would save your $ and buy a used reputable x pipe of another forum member.

Could you elaborate on why you didn't like the x pipe?

It made the car really raspy and it droned like crazy it was more annoying than aggressive the quality of those resonators weren't the best as well.

So you bought the catted version with resonators as pictured or the version with just 2 resonators that has been posted before or the original version with no resonators that first came out or the version with no resonators and then added your own (like me)?

I believe the one in the picture has quad resonators. The front two resonators happen to be where the OEM primary cats would be. But they are resonators not cats.

Well, my splitters and mirror caps came with the car so they OEM. As for my rear spoiler and grills, they were pretty cheap but good quality so I'm thinking China lol.

Ok. Interesting design. The two quad resonator x pipes that I know of, Dinan and Borla, put them just before and after the x.

I'm thinking maybe the resonators close to the headers won't hurt flow, since there is nothing directly in the path of the exhaust flow inside a resonator?
