I have a question about the X02

Ok, after posting threads about deep and loud exhausts...i think i have found the one i want and it is sounding like this video....

The first part is a X02 catback with megan test pipes and and the second part is X02 catback with megan test pipes and muffler deletes...

Now on the X02 catback with muffler deletes....is there anyway i can mod that so it doesnt have the rasp sound....Because i like the growl of the second exhaust but i dont like the rasp...

So is there way way i can still have the mean growl but without the rasp of it?

I'm assuming he meant the magnaflow resonated x-pipe which actually quiets down the exhaust, thus reducing some rasp.

If you put in an unresonated x-pipe, it won't help it that much but it'll be better. Rasp is just the nature of cheap exhaust pieces like this.

If you don't want rasp, spend the money on a quality exhaust and a quality test pipe.

There isn't rasp with the x02 smartass. A tiny bit of drone if you accelerate under heavy load but that is it. The rasp is from test pipes. Put unresonated test pipes on any exhaust and you will have rasp. And his second part of the clip is without a muffler, take your muffler off and tell me if you get rasp. Really? Think before you post next time.

Think before I post...interesting you say that. I have an x02 myself and I do know that there is no rasp. I was referring to the setup with the Megan test pipes...which I also have (Please refer to my mods in my signature which I blatantly put out there), which also rasp (not too bad but it's there). Also, the guy in the video is a friend of mine who I know personally. I know his setups and I know how they sound in person. So please, lets try to keep everything chill and keep the assumptions to a minimum

See above, you clearly stated that not getting a "quality" exhaust leads to rasp. x02 is widely regarded as not a high quality exhaust and thus by your statement should create rasp, which it doesn't.

Test pipes quality isn't going to make a huge difference if in both cases it is unresonated. He has to go for at minimum some resonated tp's, or art pipes, or hfc's if he wants the volume and not the rasp.

Why not got for authentic quality exhaust like HKS, rather then X02 or ARK

I used to have an XO2 and it was good quality. I had it for almost 2 years and after I took it off, it looked fine. The new owner is still happy with it. The HKS is nice BUT, I really didnt like the way it sounded. Too high pitched for my liking and there are many people that agree with that. The XO2 has a better tone IMHO.

Because they are different? People prefer different sounds for their exhausts, none of the listed exhausts sound exactly the same. Also some people don't like spending many times more for the HKS when it doesn't even produce as good of gains as the x02. Pure preference.

It sounds pretty mean in these clips, but I'll guarantee you the drone inside the cabin is probably so bad that you won't even want to drive it.

I built a full custom exhaust on my G35 and I experimented with some different things in the process. I was running straight ART pipes for a few days and it is loud and mean. You would be surprised how these cars sound with no exhaust... It sounded like a dragster, no lie. But the drone was so bad in the cabin that my head felt like it was gonna explode after 2k RPM. You can forget about listening to the radio.

You will be hard pressed to find a good sounding exhaust without tons of drone or rasp. I would say you have 2 options:

Budget: Get a cheap Ebay HKS/XO2 knockoff exhaust and put a Magnaflow x-pipe in to replace the H-pipe that it comes with. If you want it louder, add resonated test pipes/ART pipes/HFC's.

Quality: Get a Motordyne TDX v2 if you can afford it.

Well now see you're just nitpicking. If you read after the bolded words, I did say "and" didn't I? If I wanted to insinuate that a cheap exhaust leads to rasp no matter what, I would've excluded it as such. Instead, I mentioned a quality exhaust AND quality test pipes and you'll be without rasp. If a person cheapens out on either, then there is the risk of rasp (read below for an example).

Test pipes quality isn't going to make a huge difference if in both cases it is unresonated. He has to go for at minimum some resonated tp's, or art pipes, or hfc's if he wants the volume and not the rasp.
Well he mentioned Megan Resonated Test pipes so I'm assuming that's what he's aiming for. The Megan's aren't exactly the best, but the rasp isn't too bad.

I have a friend with ART pipes on the x02 and it still a little raspy. Now if you put those ART pipes on a quality exhaust (I don't think I need to list examples), then you're more than likely good to go.

Please keep in mind I have these parts mentioned in OP in stages. I ran my x02 for several months, then soon followed the Megan RTP's. I also then heard my friend's (the guy who made the video) setup. I know how they sound, so I would assume that there is no need to question my judgement of quality on these parts.


In the end, if you have the money, spend it on the quality stuff and don't cheapen out. If you straight up don't have the money, then go for the x02 + Megan RTP's, it's not terrible, but understand you won't have excellence.

Question on the magnaflow X pipe replacing the H pipe on the X02. This is basically a muffler correct? I need to reduce the sound of the X02.

Is the only way to install by welding it on?

Are the part numbers 11386 or 14386?
