I personally think that the siamesed pipes are more difficult to make than the x style because of the cuts, bends, and welds you have to have to make them. Where the X is much simpler in design and is stamped most of the time.

After looking at the "X" pictures supplied by mcm95403, and the descriptions from this thread, (some of which seem backwards,) it would look like the True-X is the inferior of the two styles of X-pipe.

Am I getting closer??

In my uneducated opinion I would say yes, plus siamesed one just looks like it is less restrictive to me. Before I ever started researching this stuff I knew if I was going to get an x-pipe I didnt want to buy anything but the siamese style just because it appeared to flow better from what I knew.

i agree that there seems to be conflicting statements on which is the better flow, but i think we got it now. the siamese style, or joined at the hip as it appears to be, is the better flow than the true x type.
now someone who makes the true x type is going to come up with some kind of engineering flow printout to show why we're wrong.

Wow! Great info on this thread. I am planning to install a thermal tunnel plate and was considering adding a Corsa X-Pipe while I have the exhaust dropped. I already have the Corsa Pro Indy exhaust and love it. However, I was hoping for some performance and torque improvements. This is the Corsa X-Pipe I'm considering...

I dont think you will really notice anything other than a change in sound unless you get headers which are tuned for the x pipe but you may pick up a few ponies, just not anything huge.

I've got this particular X-pipe and am pleased with it. I bought it to improve, albeit slightly, the flow of exhaust gasses, but specially to eliminate the popping sound on deceleration from my Corsa Sports. Works great!

Rock and Roll,

I installed a joint X-Pipe on my Mid America Quadrapower exhaust this past Tuesday at Mid America. It made the exhaust note a little more mellow, not so throatie. Also, in 6th on the highway, the sound level was cut in half. I really like the setup...sounds awesome! Still has that "Vette" roar...yeah!

Well.... I am still waiting to find out which is the better x pipe???

s'noJob

Well, in my opinion it looks like the consensus of this thread is than the joined X-pipe, (which looks more like a "bump and grind",) is better than the true X-pipe.

Look at how each are described in the posts regarding airflow/hp and construction and you'll see more positive direction toward the "joined" X.

A few months ago I had my shorty headers ceramic coated inside and out at Sandersons in South San Francisco for $80. Mufflers wouldn't cost much more than that.

And Flowmaster doesn't "tack weld" ANYTHING that goes out the door. I did see some of the old mufflers that weren't aluminized steel that had rusted out badly, but the aluminized ones are many times more durable. If you make a lot of short trips and the exhaust system never gets a chance to heat up enough to burn off condensation, then it will shorten the life of the mufflers.
