Anyone have experience with Double X-Pipes ?

Anyone ever try a double x-pipe exhaust on a 5th Gen? Sounds like they might have benefits of reducing drone and creating a unique exhaust sound. No performance gain expected, just a sound change I'm guessing. Some have posted on other forums that they give a small gain in low-end TQ and a small loss of peak HP due to the extra turbulance created.

Wondering if this could be either an alternative to J-Pipes, or possibly a way to create an exotic exhaust sound?

I really know zip about these, but ran across some posts on a G8 forum. Wondering if any in our forum have tried this setup.

Here's a G8 running double x-pipes with resonators in between:

I didn't know anyone would actually do this. I was joking with someone a while back about doing an exhaust with only X-pipes and mufflers.

Yeah I know this double X-pipe sounds a bit gimmicky, but if the claims of reduced drone and exotic sounds are true, I'd like to know more.

Hope it would not be as gimmicky as the O-Pipe dual exhaust system:

Cross drilled SS brake lines are my favorite though.

Here is a video of that same car. Doesn't sound like much to me. Maybe he should have left out the resonators.

It doesn't sound bad and in theory I could see additional TQ.

Yeah, poor video. Wind blowing over the mike. Can't really tell much about how it sounds in real life. Agree that the resonators might just be too much.

This G8 is Alternative Auto Performance's shop car. It runs 11.90's. Read this about it HERE. Another crap video/audio quality there too - ARGH.

Poking around some more, I found that Bassani used to make a Double X-Pipe for the Corvette Z06, another company GT Pro makes/made them for Bimmers, Mercedes and Infiniti's. Yet another, Art Performance makes them for Lincoln LSCs.

All seemed to cite removing drone as the primary reason for the design. Not a new idea, but not sure if a good idea
