Has anyone heard of CGS Motor Sports for Aftermarket Air Intake & Cat Back Systems?

i have to agree that the factory unit looks to be pretty clean design and most of the gain will be in the replacement of factory mufflers with the high flow (also louder) mufflers.

in all honesty even though barely any flow is going out the passenger side... i doubt a proper flow distributing y would make any difference... imo, the dual muffler tips seems to be more for design than function and the whole thing could have been designed with a single muffler. i'm glad they did it this way because it looks cool to have dual exhaust tips at the back.

an x pipe wouldnt work in this case because in that scenario each header has its own pipe going all the way to the muffler/exhaust with maybe an x or h fitting at the middle to help with flow.

The factory Ex system is a 3 into 1 header > goes into a cat > then both sides merge into one pipe going along the driveshaft tube > into two more cats in series > resonator > spit into two mufflers.

and imo dont think its worth having it customized headers going into their own pipe with an x pipe in the middle... extra weight with the two pipes (also 2 resonance pipes?) for possibly no gain.

with that said... i still think the kink at the top could still flow better if it was more round/oval. i know they said engineers told them ok but at this point i wouldnt believe them.

dispute the charge with your credit card company and use the money you get credited back and order that magnaflow on sale.

Sorry to hear that, but it was what I was thinking when I looked at that pipe. It was hard to tell from the photos what the flow would do as the joint is just a wee bit past the beginning of the angle, like maybe it would catch some perfect flow or have some sort of internal flow control (which would reduce efficiency). I really think the best solution may be to keep everything stock back to the mufflers, maybe replacing the resonator but maintaining the factory piping. The Magnaflow system has a better Y but the factory piece is the best looking of the three. I hate to say it, but I think the days of low- or no-cost horsepower are gone. With the fuel efficiency requirements on modern vehicles the manufacturers can't afford to overlook anything. Of course, they are also dealing with a financial restriction as well as owner satisfaction (loudness). Going with something lighter weight and less restrictive (louder) gives the double benefit of performance through weight loss and reduced back pressure- again assuming that the enigne really does perform better with a different backpressure.

Now if someone wants to engineer an X-pipe... But that would require some serious engineering to get it right with the flow pulses, etc.

Tio, any updates?

I just got back from Peru, so now begins the fun! Just a little frustrated I guess every time I see it. I'm gonna get ready to send it back and see what they say.
