Guys whats the difference between H pipe and X pipe. I know the shape but what's the performance difference. I've heard that X pipes sound more Euro (referring to X and H pipes for mustangs) while H pipes kept more of the traditional sound. Just out of curiosity, b\c I always thought our cars would use an X pipe like Stillen, but the Borla uses an H. One better for top end power while one has better torque? Or is there no real difference as long as it's equalizing the pressure between both. I'm def. going for the Borla, sound great on other cars so it should be sweet on ours. Highest HP around is just icing on the cake.

Borla Performance Industries is proud to announce the release of Cat-BackT system part number 140045.
This system has been designed for the 2003 Nissan 350 Z equipped with a 3.5L V6 engine and automatic transmission.
The 140045 installs to the flange just after the catalytic converter and eliminates the factory Y-pipe.
Like all our systems, it is made from full aircraft quality T304 stainless steel.
This system is a true dual exhaust designed with an H-pipe.
It is a split rear exiting system with a 4 1/2" single round, rolled edge, angle cut tip at each exit.
This system consists of dual 2 1/4" inlet pipes to a 2 1/4" H-pipe assembly.
Exiting the H-pipe assembly are dual 2 1/4" pipes to a pair of 14" long by 4" diameter round mufflers.
After the mufflers, a pair of 2 1/4" over axle pipes lead to a newly designed X-flow muffler.
Our new "True Dual" system has resulted in gains of 23.5 horsepower and 14.7 foot pounds of torque
throughout the entire RPM range which is more than brand "S" who claims 13 horsepower and
14 foot pounds of torque@ 5500 RPM and up.
Our testing has shown not only that brand "S" does make the power they claim, but it also shows something
they fail to mention, that below 5000 RPM they actually lose 10 horsepower.
Weight comparisons show that the factory exhaust weighs 62 pounds, brand "S" weighs 74 pounds,
and the Borla "True Dual" system weighs only 50 pounds.
That is a huge 24-pound savings over brand "S" and a 12-pound savings over the factory exhaust.
Combine our new "True Dual" Cat-BackT exhaust with our newly developed headers (P/N 17221) for gains
of up to 25 horsepower and 17 foot pounds of torque. Wow! More power, less weight, great looks and sound!

Damn, now this is really tempting. One of the best prices and best gains of any exhaust out there right now...hmmmm. I want to believe this I really do, but it sounds too good to be true. But on the other hand, designing and then producing the right product at the right time can often appear that way. I hope it's true!!!!
I expect dyno sheets (independent) and sounds clips on June 3rd then!

He told me two weeks. I talked to Borla personally and they confirmed that the exhaust would be finished and ship in app 2 weeks. Now we wait. I have the camera ready for the video and some sound clips!
