Borla Exhaust Claim 20+ HP!

Borla is known for their great sound and performance, but can it be true that their TRUE CATBACK EXHAUST system for the 350z actually produces a 20+ hp gain?

They are actually a very reputable company(certainly not known for false claims) , and I'm just wondering if anyone's tried their system and experienced the power first hand?

Surely a 20+ hp modification could be felt in real world driving conditions...

Also, has anyone independantly tested the system via a dyno or a track?

If this system truly produced 20+ hp gains then surely a combination of the Borla exhaust and TRUE cold air intake would yeild very noticable, 14/mile impacting gains!

I'm very curious about this system! Please respond guys!

Thanks

20 + hp from only an exhaust?? not true

I'm not absolutely positive, but I think the gains are due to the fact that the 350z exhaust is not a true dual exhaust system and this Borla system is. However, I may be incorrect.

Regardless, here are some websites claiming 20 hp gains from the Borla system:

WWW.ULTIMATEZ.COM states, "The new "True Dual" system has resulted in gains of 23.5 horsepower and 14.7 foot pounds of torque throughout the entire RPM range!"
(These guys tested the exhaust independantly)


WWW.ZCARPARTS.COM claim, "16-20 HP Gains using this Borla system!"

WWW.PERFORMANCECENTER.COM says, "The Nissan 350Z gets impressive power gains with a Borla Exhaust System installed!"

if it is true...then that i seriously badass for an exhaust system...i just find that claim slightly hard to believe...

Well, I don't know if it's true or not. However, for what it's worth, a Nissan rep at the International Auto Show this past feburary told me to "forget wasting your money on a Nismo or any other cat-back exhaust, a borla is a true dual and willl give you a 20HP gain. Like I said, I don't know if it's true either (I kind of thought, umm, right...when he told me that, lol), but I was told tht by the Nissan rep @ the international auto show while looking at the nismo parts that wear finally being sold in the US..

Sorry I don't know more.

+20hp..... likely with forced induction.....hard to accept in a nat. aspir. Z

I just remembered that the AF 350Z had the Borla True Duel Exhaust. It was installed around December 27th, 2003, at the same time as XERD Long-Tube Headers, K&N Typhoon Intake, and Z-Xtreme 6-Wire grounding kit.

The car is Igors car, isn't it? Maybe someone could ask him what type of gains he saw.

It' near the bottom of the page, December 27th, 2003. It doesn't talk about gains though, so you'll probably want to ask Igor.

I hope that helps a bit.

Great Idea! I'll shoot in a private message right now and let you guys know what he says. Thanks.

good idea

Yeah, I suddenly remembered that the AF 350Z had that exhuast on it and thought, hmm..., lol. Keep us posted on what you find out.

Highly doubtful, plus even though you might see higher peak HP numbers from a true dual (maybe) I think that with an NA setup you are likely to lose low end.

A lot of us may be skeptical, however, Igor has one on his 350Z, the "AF350Z." Just wait until they can get a reply from Igor, he should know how much of a gain it really has. He put one on the AF350Z (his car I believe) on Dec. 27th, 2003. All the doubt and spectulation really doesn't mean anything if we've never had a Z with one installed (to compare the before and after). Since Igors has that exhuast, he should at least have a rough idea.

It's down near the bottom, one of the first things he did.

I messaged him but have yet to receive a response. I'll let you guys know if and/or when he messages me back!

I think Borla is a good bang for the buck, but 20 at the wheels . . . unlikely. I don't think Igor dynoed it with just the exhaust. My guess is the only dyno he's done is with the entire setup (Vortech, etc).

yeah...i have heard that borla is a good exhaust to get...but it is just hard for me to believe that ANY exhaust system alone would give you 20 extra hp...even an Amuse Titan R1 wouldn't give you a 20 hp gain

Hmm, just had a thought. Maybe it's not a 20HP peak power gain like we are thinking. Maybe it is a max gain of 20HPover stock at a certain point in the power curve.

For example, maybe the peak gain is 11HP, but at 4250 rpm the gain on the power curve is 20HP over stock...at that point on the curve.

Again, no basis this is what they mean, I just thought maybe thats where the number came from, if it's indeed true. That number would be much more believable than a 20HP peak gain is.

Highly doubtful, plus even though you might see higher peak HP numbers from a true dual (maybe) I think that with an NA setup you are likely to lose low end.

I agree.

In Z compact magazine they did a exhaust shoot-out. The borla came in at 7HP at the rear wheels. IMO Apexi had the best bang for the buck. If your going NA stick with the Y pipe design. With dauls you will loose low end to mid range torque.

Did they test the Injen exhaust? I currently have an injen exhaust system for my 350z and I am not too sure how much horsepower I have gained. I would like to see another dyno because well I don't know if I can turely believe the Injen's dyno sheet.

If you put true duals on a car. Im sure you would gain some high revving kick. Correct me if im wrong, but won't u lose all the backpressure? if so, say goodbye to all the low end torque.
