Here are the final results...same place, same dyno. Only thing changed is the Borla, no other mods.
BEFORE, baseline run
Peak WHP baseline: 348.92
Peak WTQ baseline: 335.73
AFTER Borla catback
Peak WHP Borla: 377.72
Peak WTQ Borla: 359.98
Peak gains of: 28.8WHP and 24.25WTQ
I knew this system would give substantial gains because of my butt dyno felt power everywhere after the exhaust.
What's really impressive is the power gains between 5500-6200. Since the Borla system eliminates the stock dip in power at around 5700rpms, it gained a whopping 44.4WHP there.![EEK!](https://www.clublexus.com/forums/images/smilies/eek1.gif)
My car is very consistent on this DynoJet, it put down back to back 348 WHP baselines, and the 3 runs after the catback read 376,376 and 377.

I'll get a better graph up once I go home and scan the original sheet, I just took a pic from my phone since I had to go to work right after. To say that I'm impressed with this exhaust would be an understatement, for under $1000 it's amazing value for the power.![Thumb Up](https://www.clublexus.com/forums/images/smilies/thumbsup.gif)

JoeZ is 2 lbs lighter than stock, borla is 15 lbs lighter, according to the weight thread.
The bends before the rear mufflers are straighter on the JoeZ, though.

I would buy borla...Joe z didn't net this much power. Plus joe z exhaust I don't want to pay 300 more for polished pipe I can even see when installed. Borla is definitely lighter than Joe z

Tiny little imperfections along with dents and dings might not be as detrimental to performance as one might think. MT did a test on an engine dyno by bashing headers in on a big block to see just how much power was lost by dimpling (or just smashing them all together). You can read about that and watch the video here:

RWHPower on all these CATBACKS are the same.. 20 to 30 RWHP range
You shouldnt make judgements based on this dyno or that dyno..

And you're right we don't polish the pipes anymore.. They come in a very nice brushed satin finish.
Happy Modding !!

The reason why its lighter is because we fully secure our connections with 304 SS - CNC flanges & gaskets.. (not slip fit clamps)

The slip fit clamp design on the Borla is TERRIBLE, I do not wish them on my worst enemy.
