I personally don't need to hear it, as I know that anything with the 'Borla' name is good enough for me. (and hearing it thru tinny 2" 'clock-radio' computer speakers is not going to help anyone.)

Mr. B is a legend in the Nissan 'Z' community - there is 'Borla', then there is 'everything else'.....

Mine is in the mail.

As to bang for the buck, sound is a pre-eminent factor in my book, and I don't like the exhaust note of the factory '8'. (Yes, heresy, but someone had to say it!)

I am also in line for an ECU fix, why not both?, (I have more than ONE buck!) because if the ECU fix releases the smogged/choked up top-end, the first thing people will want is a 'cat-back' to maximize the new curve....

How difficult is exhaust to install? Could I (totally not mechanically oriented) do it myself? I'm good with tools, I've just never worked on cars much.

 

Simple, really, even if you haven't done it before it should only take 30 min. A couple of bolts and the hangers, that's it! Hell, I think even wakeech could pull it off

D-san

 

I would take it to a shop for install its not expensive

 

The temp can effect the dyno#or hight from sea level or he could have a MODS on his car ?

 

Haven't found this anywhere or seen the question asked, but is there any weight difference between the Borla and stock exhausts?

 

Can anybody record and post the sound of Borla muffler?

 

I have no idea of the actual weight but the shipping weight was listed as 30 lbs.

Has anyone actually received their Borla exhaust? I placed an order directly with Borla the same day it was added to their website but after waiting a month and making a few phone calls they said that they lost/canceled my order. So last Friday I ordered the same Borla exhaust through Vivid Racing for significantly less and know that I'll have it in a few days (already have a FedEx tracking #). Hopefully Borla's engineering is better than their customer service.

 

no sound clips out yet

 

Speedracer -

You said you got your catback from Vivid Racing, right? Is that the same company as http://www.vividracing.com/ ? If so, I just hunted around on their website and found no listing for Mazdas, to say nothing of the Borla cat back system for the RX-8. Can you provide a link, and even more importantly, how much cost?

Thanks,
Omi

 

I couldn't find any RX-8 info on their website either but don't worry you can find all of the info that you need on this forum. Just check out the first post of this thread.

 

Excellent, thanks!

 

I received and installed my Borla cat-back exhaust today. Construction looked top notch with its smooth welds, oversized mounting flange, and gentle pipe bends. The size of the 3" tubing looks gigantic in comparison to the stock exhaust and should help the car breath a little easier. Likewise the 4" exhaust tips fill out the cut outs in the rear body work a little better than the stock setup but that may also cause the plastic near the exhaust to melt. With that in mind it may be wise to add the metal exhaust trim pieces to act as a heat shield.

I'm sorry to say that I didn't take any photos of the install because I was in too much of a rush to try it out.

When you turn the key and bring the Renesis to life you'll notice that there is something different, something a little more menacing. At idle the tone is deeper and a little louder than stock. Blip the throttle lightly and you are greeted with a satisfying growl. With a quick lift of the throttle it is followed by a light pop that adds a little punctuation. Once on the road you'll notice that you can finally enjoy the sound of the rotary that lies beneath the hood and as the revs climb the music turns into a mellow whine until you hit the redline chime.

In my opinion it is all good but you will be sorely disappointed if your the type of person who enjoys the deafening sound of a riced out Civic. :p

 

Thanks for the review, any chance you can get us a sound clip? :D

 

if you dont mind , please let us know how the mpg varies after the exhaust

 

Take some pix:D

 

Thanks and great review. You didn't mention and difference in performance however. Was it noticeable?

How long did the install take?

 

this is great news
congrats

 

I actually can't believe mikeb didn't ask this already, but could you possibly post some pics? It would be greatly appreciated! Would you definitely recommend this exhaust?

 

nice review...

i would like to hear a sound clip..

i for 1 can not stand loud cars.. it was kewl in HS but now its just ANNOYING!!!! i like a nice low rumble.

and the last thing i need is a fart pipe sound. I have a hole in the muffler of the civic its driving me nuts! i dont have the $$ to repair it yet

anyway good luck with it and hopefully u can get a sound clip and pictures

 

< chanting> sound clip sound clip sound clip.... :p

 

Any noticeable power improvements?

-Mr. Wigggles

 

Hmmm... I've never tried to record the sound of an exhaust. I'll try using my camcorder but I'm not going to make any promises on the quality of the recording. I know that you guys are eager to hear it so I'll try to post a clip tomorrow along with a photo or two.

 

The removal of the stock exhaust was straight forward and self explanatory. [list=1][*]Jack up rear end and place on jack stands[*]Remove rear tires, rear wheel well trim, and exhaust trim[*]Remove spring bolts from exhaust pipe[*]Remove grounding strap from muffler[*]Remove rubber exhaust hangers - I had a bear of a time trying to remove them so I just cut them off with a utility knife[*]Remove the exhaust[/list=1]


Installation proved to be a little harder.[list=1][*]Loosely assemble 3-piece exhaust[*]Attach rubber exhaust hangers to underside of car - I bought new hangers for less than $10 from Autozone[*]Line up exhaust and attach to rubber hangers - adjust spacing of parts as necessary[*]Install spring bolts - this step was a major pain in the butt (M10 1.25)[*]Verify exhaust alignment and torque the exhaust clamps[*]Attach grounding strap - a nut (M6 1.25) was not supplied with the exhaust[*]Reattach exhaust trim, rear wheel well trim, and rear wheels[*]Remove jack stands[*]Turn the key and listen to the Renesis come to life :D[/list=1]

The sound is awesome and it is just as smooth as the rotary which I think is fairly unique in an aftermarket exhaust.

The difference in performance is fairly small and you will only notice the change between 6k-9k RPMs. In that range the engine revs a little easier but I don't think that it will make an appreciable difference in the 0-60 sprint or the 1/4 mile.

 

I'd love details about the installation. Did you do it yourself? If so how difficult, how long, etc.
