Catback + X pipe = ?
I'm strongly considering the addition of an X pipe to my exhaust (which is currently stock save a set of Borla Stingers) I'm told the True X pipes produce a similar scavanging effect as tuned headers (thought not as much) Headers are a little out of my price range and my mechanic says it's a PITA working on cars with them.
what can i expect with the addition of An X pipe? Sound, noticable torque etc?

Mostly resonance and sound filtering. The X-pipe does nothing for RWHP but will help with the popping noise fron cat detonation and will smooth out some of the exhaust turbulence before hitting the mufflers. In my opinion, after installing my Corsa x-pipe, a waste of money. But, it is your car and your money.The addition of an x-pipe will not hurt or help anything as far as RWHP is concerned.

If i'm not mistaking, isn't the corsa the "two pipes welded in the middle" style? I was thinking the style with the 2x2 merge in the middle (complete crossover)

What difference does it make, if the pipes are welded together with large hole between, or in an X shaped "true" crossover? The exhaust gases merge either way, and flow unimpeded to the mufflers. It's just a cosmetic difference.

There are benefits to adding an X-pipe. Sound, increased flow over stock and elimination of decel popping.
If wont give you 20/20, but there is definitely a performance/sound benefit. Otherwise, there are alot of companies liable for false advertising. My two cents. No change please.

This was my reply to another x pipe question:
I think that the manufacturer does indeed matter. Take a look at the center section on some x-pipes. On some all they do is cut a section out on the sides of both pipes, bend them together and then weld the sides of the two pipes together. There would be no true crossflow on these.........
What you want is a true "X" section that is going to flow across from side to side for better scavenging. IMHO, Bassani makes the best center section and has the best cross-flow as a result. Bassani's center section is a custom made piece and with my Corsa Indy's sounds great..........nice even exhaust pulses at idle ---- no more putt! putt! putt! motorboat idle sound.........

The Magnaflow merges in the middle and I picked it over the others because of quality. I went one step further and installed muffler bands to my connection to the stock pipe from the manifold. They seal better than the u-bolt and won't rust or drag.

An X-pipe gets rid of the motorboat "gargle" the car has at idle, and smooths out the sound while cruising.
I put LG Pro longtubes on my car, that kit includes an X-pipe. The sound is much improved now, the resonance is gone, and the deep hollow sounding "boom" the exhaust once made is replaced with a smooth high pitched scream now. I love it, and I attribute 90% of the improvement to the X-pipe.
'02Z, stock Ti mufflers.

I have B&B Bullets and a Magnaflow X-Pipe and love the combination. The car sounds like a Lamborghini and is not loud despite what the rumor mill says.

I put a Magnaflow X pipe in after installing my granatelli catback exhaust. It did change the tone when getting on it to have the lamborghini sound. Sounds awesome.

Don't know if this applies but, I put on an x-pipe with my American Racing Headers and B&B Bullets........ The sound is quite exotic. It's higher pitched without sounding like rice. The exhaust pulses are blended into a very smooth sounding idle. IMHO when you step on it, the x pipe kind of makes the car sound like a Lambo or some other exotic with a solid note. No hollow boom sound.
As far as the power effect, I was told that the x-pipe creates a vacume effect.

Well I happened upon a WCC X pipe (2x2 style) here on the forum and bought it. Plan to have it installed early next week depending on shipping. I will provide before/after vid clips. (i'm too cheap for a dyno though)
