Wow, great information. I wonder what the db readings would be with those systems and an off-road header.
I am running the SVT cat-back on my ZX3 to keep my header quiet. Thanks again Ron for doing this shoot-out! |

I've had the Borla 2.5" on my SVT for a year now and have had them on my Bronco and VW...and it's good to see they make a great product...Congrats FS on your exhaust...Too bad it wasn't out earlier...your price may be cheaper than the $489 I spent on my Borla..

The MBRP with a JBA and FC Cat is about 110db it's so loud it hurts your ears!
Good info guys thanks for all the work. I would get the HKS but I don't like the look so FocusSport it is! |

Great work you guys. I love the results; everything looks professional and well thoughtout. I have one question though. I figured that the regular Focus Sport Exhaust would be quieter? Focus Sport says that their exhaust is one of the quietest on the market...
I will end up getting their exhaust still, but I think the Stealth option will be added. Even though I am keeping stock header and stuff, I want my car to be quiet and unsuspecting; especially once the JRSC is installed.

I notice the MBRP was done with the 2.25" system and still did within a wisker of the top 2
![]() I said it before and I'll say it again, you can't be fast and quiet at the same time.

Cool...this certainly makes choosing an exhaust much easier. Thanks for the concise and informative reviews guys. Now I'll just go back to patiently waiting for the FS exhaust for the SVT and to see how the Apex'i exhaust works out for belacryf
Later all.-- Kevin

First, let me say thanks for this info. I imagine it was a huge undertaking.
It is interesting to see all of the posts lauding one exhaust or another. The praises are usually for the exhaust the poster owns. What i take from this test is that the results from one exhaust to another fall within the margin of error of the dyno. Folks, we're talking tenths of a hp or tq here! I'm confident that if you reran the test you would see different results. All this test shows me is that if you buy a quality exhaust, no matter the brand, You will have basically equal results. Now to those who are toutng one exhaust over another based on these miniscule differences, I must ask, what if the results were weighted by price? Is exhaust "A" worth nearly double Exhaust "B" for a couple of tenths that may dissapear on the next dyno? If I were buying an exhaust from this list based on the results posted, I would probably pick the Magnaflow based on it's performance and the fact that it can be bought for under $300.00 shipped and it's right there, in every category, with exhausts costing hundreds more. But, someone else will see these results and reach a totally different conclusion. Well done Ron! |

Correct me if I'm mistaken, Ron. And you don't need to reset your ECU for a cat-back exhaust. I hope Ron didn't bother with that, as it would have been a waste of time. As a participator in this test, I was VERY concerned about consistant test conditions and the methods used, as I'm sure all the manufacturers were. Some may not agree with the way the test was done, but at least it was consistant with every kit, so no one can really complain about the results (not that there was any REAL complaints so far in this thread). Thanks for all your hard work, Ron!

Hell, many people can't feel a huge difference when they add pullies, or a chip, do you expect them to "feel" a 1hp advantage on an exhaust? Again, great job Ron.. (EDIT) I just read another post with HP & TQ per dollar: Quote:

i say 2.5in the borla is 2.5, so why not? ive seen a lot of posts say that if you go too big of a pipe diameter with little or no mods that you lose low end power

Keep in mind the test car they used being stock, would be pretty choked up. You're not going to see the real advantages or disadvantages of tubing diameter in this type of test.

Ummmm there seems to be alot of speculation of diameter size 2.5 vs 2.25. While I still think 2.5" is to big for an NA 2.0 liter zetec with a restrictive head (non-svt), some seem to state emphatically it's the better size.
I haven't found anywhere that Ron states what diameter exhausts were tested, so we should probably wait to see if he has that info, and if he does and he posts it, then you can start arguing diameter. But for a normal zx3 I just don't see 2.5 being a wise choice. |

Good job Ron, rise ur right hand and give urself a pop at the back.
There is a few things I would like to see 1) what's the decibel level on the stock system(Hope I don't miss it somewhere)? That will give a better idea on how loud after mkt are. 2) A better dyno picture. 3) Pick one cat-back(FS, MBRP...anyone), run it with a 2.25" flex pipe(don't have to name who made it if there is any concern) and see if there is ANY gain. That will help alot of people get over the "while ur at it, why not" mentality. |

Good point, I didn't include the stock decibel meter readings. I'll append the article, but in the meantime, here they are:
Decibel @ Idle: 61dB Decibel @ 3K RPMS: 71dB Decibel @ 4K RPMS: 77dB |
