Also, has anyone ever bout one of these?

This has GOT to be the most popular exhaust on EBAY. Its the cheapest...but is it the CHEAPEST?LOL.

 

Thats the X02 knock off which is the knockoff of the knockoff... then there is another one on ebay that copies the double knockoff which makes it a triple knockoff.

 

^^performance wise, the X02 has to be the best bang for your buck in the catback exhaust category.. Then you can on with high-flow cats and test pipes.

 

LOL. Cool. Thanks. I think I'll stay away from the ebay one then, lol.

 

question..on the XO2 do yall use the silencer on it? Does it sound better without it or with..?

 

Silencer? I don't have one and one didn't come with it. As for an update, been about 3-4 months now and still no rust in any way. Also, still sounds sick and everyone I know LOVES it. Only change I'm making is custom X-pipe with the 2 resonators.

 

I don't mean to bring back an old thread but...

I just put my stock exhaust back on (have test pipes) and wow...the power loss is very noticeable.

IMO, there is a power loss below 3k RPM with the X02 and a great gains after all the way til redline.

People will "hate" on the X02 all day but for $250 brand new, you can't beat it. Next to test pipes, the cost per HP ratio is worth it.

Then I found a dyno of the X02 on my350z.

 

Wow! Old thread.. I'm going a custom route right now..

Stillen true dual all the way without the stillen mufflers.. Getting 2 Megan Racing M-SpecII mufflers and doing a custom true dual. Should look and sound good.

I was going to do a custom true dual HKS carbon TI with that same stillen piping but everyone and their mothers told me that its a waste of money to buy the HKS carbon ti mufflers.

 

Sorry, noob here. But what should i take out of that dyno two posts up? Good/bad? How much hp/tq was gained?

 

I can't even see the dyno - just a red X or else I'd decipher for you .

 

Here you go, decipher away please!


Here is the image location: http://img191.imageshack.us/img191/5532/documentk.jpg

 

Blue = torque
Green = HP
Red = AF ratio


showing a loss of HP/TQ below ~3700 and it starts to gain TQ/HP around 3900 rpms

Tough to say, but it looks like they are claiming about 20 tq and 25 HP as largest gains and peak gains of roughly 8 or 9 tq and about 15 hp.

The AF ratios are changed obviously.


This is not to say that this is completely accurate. Margins of error and allowing the ECU to adjust while on the dyno and several variable with every part can affect the outputs here. Keep that in mind.

 

Thnx *****!

 

i have x02 and i got the tips cut off and welded on 4 inch magnaflow tips cuz there titanium polished look - first the exhaust has best dyno with intake/tpipes and headers i gianed 38 whp with all of that after osiris tune but besides that its a great sounding exhaust and very loud! i bought for 400$ new id rather do that then buy hks hks sounds ugly

 

You going to need to add the Magnaflow x-pipe to tame it down. You won't lose power either. When I got mine tuned at church, they said the x-pipe would actually help with scavenging. I got mine for $250. For that price and with the gains, it's still well worth it even though the quality isn't the same as an HKS. I have a neighbor with an Injen true dual and from the looks of it, mine has better fitment and is quieter.
