BORLA® Exhaust for the GT350

Are they editing an exhaust video or Avatar 2?

Realistically? No. Relatively? Probably lol

To be fair, their videos are quite thorough usually, must be exhausting to put together.

It's absolutely true and here's why. Our muffler outflows the stock muffler with the valve open (and closed), and our X-Pipe outflows the factory X-pipe.

I posted pictures before of the difference in X-Pipe designs so there's no mystery why we were able to find power with our X-Pipe.

We also found some power in our muffler and some have questioned how that's possible. The reason we were able to find power in our muffler is because the stock muffler has an internal diameter decrease. In other words the open valve circuit, or the loud circuit if you will, necks down to a smaller diameter inside the stock muffler. The Borla muffler maintains the same diameter throughout.

[FONT=&quot]The major area of restriction in the stock muffler looks to be the tailpipe portion where it has a nominal 2.50” valve that has ridges that restrict to 2.25”. There are also complex tight radius bends in the tube. In contrast our tailpipe uses a nominal 2.75” valve without ridges and therefore no restriction. Our tailpipe, also, is nearly straight.[/FONT]

Below are the flowbench results of just the mufflers. Stock vs. Borla and the flowbench results of the entire catback. Stock vs. Borla.

Normally I call BS on most manf'er claims as such but I'm listening. So I have a question then: aren't factory catalytic converters which are often 800 - 1200 cell count bricks usually the biggest restriction? Or is it that the restrictions by the muffler are so extreme that even though cats are a big restriction, there's so much gas piling up in between them that it chokes on itself?

Going on 10 days and still no video from them....Voodoo will post his up soon and borla will be kicking rocks still on this editing.

Okay, great question.

The gains are found in 2 areas. The X-Pipe and Muffler setup.

Below, I've posted pictures of both the OEM X-Pipe as well as our (Borla's) X-Pipe.

You can see that the OEM is really not a true X-Pipe but rather a stamped piece that's not ideal for flow. Also, there's a diameter decrease going into and exiting the X-Pipe and resonator.

The Borla is a true X-Pipe that maximizes flow and maintains the 2.75" diameter throughout.

Our straight through mufflers also outflow the stock muffler configuration.

If you have further questions please let me know.

is the picture of the Shelby exhaust a GT350R or GT350 ????

Gt350. The R doesn't have resonators. They both share the same Xpipe

lol how did you pick up more with a catback than you did with headers... lmfao

I see what you did there

Where did u get this from? They haven't installed headers alone or tuned any of it.

I contacted Chris at Borla and I should receive mine this coming week. But remember I have ARH long tubes and off road X pipe.

 

[Zitrosounds]

Also agree with this.

Agreed! Sounds like he signature sound is lost.

David, we get a teaser video or you're banned.

well David did say they gained an additional 12hp from headers. But not headers alone.

Post 18.

I dig the power gain but if the sound looses its character, I'll keep the stock setup. My car, testing camera placement. Its good!

Once you install long tubes and X pipe you'll never go back to stock. The throttle response and hp/tq increase are big gains. You do not lose the GT350 signature sound when using the stock mufflers, its enhanced! With the magnaflow cat back system on stock headers it sounds like a lot of base to me. With the Borlas on stock headers were not sure yet. When I install my Borla system on my ARH long tubes and if it takes away the GT350 sounds, I'll be selling them.
