Sounds great, looks great, I'll take two.

Yeah, you did a great job with the sound clip, speedracer. Was that from inside the cabin?

Speed Racer

I set up my camcorder about 5 feet behind the car. I've got a cool looking video clip (820kb .mov) that really shows you what was going on but I can't find a way to post the file.

On another thread someone suggested using Imagestation. They only allow MPEG-1 for video and I can't get iMovie to export to that format. Do you have any suggestions on finding a place to host the video?

i can't open the clip... help/! is it .php ? what program to use for that?

Speed Racer

It is a .moov file and you should be able to open it with Quick Time.

Add a .mov extension and double click it for simplicity.

Nice find!

U. N. O.

nice, very nice find and pics...

there is a place/section that it needs to be whelded? am i wrong? i though this is something you could do it yourself..!!

Speed Racer

The exhaust comes in three pieces: mid pipe, muffler w/ left tail pipe, and right tail pipe. Everything is secured with two "accuseal" clamps and no welding is required.

ffiiuuuuu :p good to know, cool, cool , can't wait for dyno results..!

I too had the Borla kit on my zx2 and i was VERY impressed. I know it was an escort and all, but that was still a DAMN fine car for 12,900... :-) The Borla exhaust, along with some minor tweaks and mods here and there, and that was an amazingly fun car to drive for the money.. a whole lot more fun than some riced out civic.. :-)
My experiences with that exhaust along with that sound clip and photos, are making me REALLY want to justify spending the money on the kit.. maybe i'll have to push off some of the accessories i was looking at buying...

Maybe I'll play that sound clip for my wife, and she'll decide it's worth it too.. :-)

sounds very deep
nice

So nice, in fact, that I took the plunge and ordered my Borla cat-back exhaust yesterday. Speed Racer, if you hadn't posted that sound clip and the first decent pictures I've seen of the Borla, I never would have gotten it.... MANY thanks!

I ordered my exhaust from John at http://www.socalmotorsports.com , and got a pretty good discount too. John was really prompt in returning my calls, and very helpful. Highly recommended.

Now I just have to wait to get my Borla.... ARG, the waiting is already killing me!

Speed Racer

Hey, I'm just glad I could sway a few people away from the ricey sounding exhausts!

Actually, it will help improve your fuel economy

U. N. O.

any proofs of such statement?

mikeb

were waiting

RotorMotor

Hahaha, not if my lead foot is taking full advantage of that extra 10 ponies!!! :D

Genereally speaking (I have a feeling Wackeech is going to come in and b*tch-slap me for this) if the exhaust is flowing more freely, which is what gives you the extra power, it will also increase economy if you drive the same way.

david borla

The Borla exhaust for the RX8 improves the overall efficiency of the engine resulting in improved MPG only if you drive the same speeds you did before you installed the aftermarket exhaust.

Most enthusiasts drive a bit faster after installing an aftermarket upgrade which makes it difficult to notice the improved economy.

If you drive the same speeds as you did before the upgrade, there is significantly less flow restriction resulting in improved efficiency.

Most enthusiasts are interested in HP gains which tells you that they want to go faster. If you drive faster, there will not be an improvement in fuel economy. (Am I making any sense?)

There are many testimonials from reputable publications touting the improved MPG of Borla exhaust.

Here's a quote from Truckin' magazine.

"In addition, the new Borla system offers a deeper exhaust tone as well as a 1-to-3-mpg increase in fuel economy."

I'll try to post more testimonials as I find them.

mikeb

its true we want hp
I just figured mpg would be worst after upgrading exhaust

CraziFuzzy

This is true for MOST efficiency based upgrades... things like intakes, exhausts, headers, underdrive pulley's, even some head porting (that's the top part of one of those 'piston' engines) all increase the efficiency of the engine, so it has to do less work when cruising, which is what increases efficiency... Of course, on the other hand, if you put the pedal to the metal, they also allow MORE air and gas into the engine, so you burn more.......

U. N. O.

these testimonial will not be too acurate since it won't be from people with an 8 but with other cars.. the exaust behaviors in each car are different as so it is the intake so some aftermarket exhaust (borla in this case) might be a "downgrade" instead of an "upgrade" making mpg worse.. please note that i am not saying that this is the case with the borla to the 8 but it could be. until we have REAL proofs with tests and owners experiences we won't know 100% therefore saying a testimonial like yours is just too vegue.
I might even say that it could be purely marketing/ advertisement given your screen name.. thats my hole point!

david borla

I apoligize if this is confusing, I guess I need to explain it better.

There are certain elements of physics that apply to all vehicles and this discussion is a classic example. What we are discussing applies to all gas powered vehicles including motorcycles, airplanes and boats. The testimonials I posted are just examples.

Most importantly it applies (as Crazzifuzzy stated) to more products than just Borla products. As a matter of fact, many aftermartket exhausts will improve your fuel economy.

Any aftermarket performance product that provides more HP than stock at the same RPM will help your MPG if you drive at the same speed you did before the upgrade. This is because it will take less effort from the engine to reach the same speed.
