I found it odd that there were no threads concerning X pipes. I tried searching for hks, x pipe, hks x pipe and nothing came up relating to x pipes at all. Obviously I have the hks and i wanted to know what kinds of x pipes are available. I read somewhere that the x pipe is better than the hks h pipe, in terms of flow and will produce a better sound, is this correct?

Y-pipe is a common replacement component for OEM exhaust. X-pipe is not.

Keep in mind that once you replace the OEM exhaust, there is no standard mid-pipe replacement. If you want to go X to H or H to X this is custom work.

Actually there are many threads discussing x pipes. Search magnaflow x pipe in the Intake/exhaust section. That seems to be the best fitting, sounding and power wise for our cars. Note: This will only work with true dual exhaust systems. I had one on my injen exhaust and wow was it a improvement. Brought a little VQ sound, restored low end tq, killed any rasp caused by test pipes.

So true,

i have the xo2 that sounded like **** with Resonated Test pipes!
Added a magnaflow X pipe to it(resonated) and that VQ sound that Freedonuts is talking about is back, I've had 5 or 6 different exhaust including ti-c,bassani,nismo, etc. and this Knock off gets the most compliments!!

im going to dyno my car on Monday so ill record some video clips so you can see what im talking about!

Just an FYI, the Magnaflow "X" Pipe, is actually a combination X Pipe and Perforated Core Muffler. It's not a "true" X-Pipe, which is essentially a 2-1 collector welded to another 2-1 collector, with the single sides connected.

The reason it quieted down the test pipes is because its also an additional muffler. The Magnaflow piece also has a good amount of muffler volume as well. Volume as in displacement, not decibels. The results with test pipes is not typical for all X-Pipes. A standard X-Pipe would probably have still kept the entire system fairly loud with test pipes.

The design of Magnaflow's resonated X pipe is a "true" design IMHO. Just with sound deadening added. It doesn't affect flow or performance:

I think any effect it has on performance or flow can be minimal, and can function largely similarly to a conventional X-Pipe for all practical purposes on the Z, however, the exhaust flow is exposed to the larger volume of the muffler chamber so it can't function entirely like a closed pipe.

TRUE X PIPE!

Not sure why the resonated X would perform as an X on a Z but not like a closed pipe version? This design doesn't hinder flow and therefore shouldn't hinder any scavening effects.

I have the CXLighting (basically XO2) and it's loud as hell with headers and HFCs. I think that magnaflow X pipe might be what I need!

T_K

Well the calculations for it are beyond me. I just find it hard to believe it offers the "exact" same effect/flow, as a totally closed pipe system. The exposure of the flow to the muffler chamber itself, has to have some effect on the pressure.

Hey guys, i got bassani TD exhaust with Xpipe. Im running megan longtube headers and its way too loud and raspy for me. If i replace the xpipe with resonated magnaflow xpipe will it remove my rasp? How much am i looking at with the Xpipe and install? Dont want to switch exhaust if this can eliminate my rasp. Thanks

freedonutss

More than likely it will eliminate the rasp. Search. I think I saw a thread about a year ago where a member had the bassani and installed the magnaflow and it worked out great. Be sure to get the correct part number. I think its #11385. Not sure but its something like that. They have a 11386 for 2.5" piping.

did you have to do custom work to make the x pipe connect to the x02/hks?

stevehl

iTrader: (29)

I guess the magnaflow x pipe will reduce the decibel level of my hks exhaust if i install it then? I was looking more for an x pipe that produced minimal gains and lounder sound. I don't want it to muffle any more of my quiet exhaust.

IsDatIt

iTrader: (21)

yes.

Thanks for the pics and the vid. I'm definitely getting this as my Xmas gift to myself! CX Lighting/X02 is too loud with HFCs and headers. I want that VQ sound back. Plus I hear that this eliminates the ringing sound that you get at WOT and idle. I think they welded the resonators too close together.

So you got the 2.25 inlet/outlet muffler?

Jairen

iTrader: (1)

I think you will need the Magnaflow 11386 which has 2.5" inlets and outlets for the X02.

I was thinking about 2.5 but I wasn't sure. I'm definitely going with that setup. Sounds much better.

Got it installed today. The H-pipe inner diameter was pretty small compared to the total diameter of the pipe. Like a 2" pipe and only a 1/2" hole. Probably barely functional. The car feels good with the X muffler. Nothing lost for sure, probably no gain or a minimal gain. Sounds much better.

Let up too early. I'll try and get a real flyby video at another time.
