That sounds great. Thanks for the vids!

I like it. Nice and deep.

Thanks,

Cost was 2000 USD, including taxes and installation. It was ordered and installed by a performance shop in Montreal Canada.

So, after a few days, here are my comments about the system:

1- There is NO DRONE at all. On the highway, or even at any speed, you won't hear the exhaust unless you press hard on the accelerator.

2- The exhaust is not much louder than stock while driving (not accelerating). But if you push your car a little, it definitely is a bit louder and has a deeper sound. (Check out the clips!)

3- Unfortunately, there is a tiny little rasp at high rev. (That wasn’t the case on my 350Z Borla). The rasp goes away when the exhaust is really hot after 5-10 min of driving. You can’t really hear it from inside the car, but you can hear it in my last vid from inside the garage. I wonder if there is some way of completely removing this.

4- I now have some comments about the clips after a second stop at my performance shop. Even if the clip assemblies fitted very well, looks like I still have a little leak that cause a small (not so noticeable) sound while reving down. You can also hear it in my last vid from inside the garage. We didn't manage to remove it completely so I am thinking about welding the whole thing… Any comments about doing or not doing this from your experiences??

I would really appreciate to hear any suggestions on the two points above (3 and 4) you may have.

Wow I cant wait to get this!

I had Borla on my 06 350Z and loved it! It sounded great with APS TP and Megan Headers.

Love the exhaust.

Any more information on your rear foglight setup? How it was done? parts used etc? I see in the video when you hit the brakes the foglight gets brighter, Does the wiring come for the brighter setting?

Ahhh! I had a feeling I would get questions about this 3rd brake light setup! I believe that this is a little off topic but yes, I redid the whole electrical setup and no, the car does not come wired for this. You need to tap into the tail lights, install a flashing module and manage to install a socket that supports a dual wire bulb. If I have time, I’ll post a DYI.

awesome.. ive always been up and down with borla.. but it sounds great on the 370

LiquidZ · 08-31-2009, 06:27 PM

This exhaust definitely sounds good. Thanks for the videos

Sorry to bring this topic back, but I wanted to mention to you that you do not have a leak. I went thru a similar experience as you and that noise you hear on decel/while revs are dropping is called rasp. Similar to the rasp you hear up top...The only way I know on how to reduce/eliminate it is if you place resonators before the H/X configuration. Thats the point where that resonance hits its peak and it seems to be THEIR that the resonators make the biggest difference.

That and I heard true-dual setups dont get that annoying sound (but I dont think they make as much power either)

So dont bother to weld (or not) because thats the same exact thing I did with my Stillen exhaust and I still had that metallic vibration/rasp sound. Look at the invidia exhaust and the placement of their resonators, thats the spot where it made the loudest sound on my car.

Trust me - I went thru alot...I stayed in the car (on a lift) while they inspected underneath as I rev'd it and I stayed their until they were done welding to only hear the same crap. Its the nature of our car and only gets louder with test pipes. I put GTM resonated test pipes + resonators before my x-pipe and it dramatically reduced the rasp...you hear it quickly ping at 2800rpm and go away almost instantly.

Mr_Z · 01-29-2010, 12:57 PM

Thanks DannyGT for your inputs...

I am not 100% sure that it's some type of rasp because if I recall correctly, we where even able to pin point it to the left side and precisely in what area...we did manage to reduce it by making some adjustment in the junction area as well...

But like you said, I don't think that welding is a good solution. What I plan to do is to lift the car again next spring and remove the clamp. Then wrap a metal tape in the function before putting back the clamp again. If that solves it then I will know that it was a leak. If not, then I will let you know that you where right on!

By now, I am sure that others have Borla on their 370z... Maybe they could tell us if they experience the same thing?

Thanks..

ZPirate · 01-29-2010, 03:56 PM

I have the Borla dual exhaust on my 370Z (I have one on my 350Z too). I experienced some of that raspy sound on decel right after the exhaust was installed.

Now I don't hear it. I don't know if that is becuase I tune it out or that it's gone away. I'll have to listen closer to see if it's still there. I do love to hear the sound of the exhaust though. Not quite as deep of a tone as the Borla on my 350Z, but it still has a nice tone/sound.

zeebra · 01-29-2010, 06:47 PM

Im stuck between this and the Berk CBE. HELP! lol Ive seen one clip on youtube of the Borla on a 370 - I think its Borla's test video and it sounds great. Do you guys get compliments on the exhaust?

ZPirate · 01-29-2010, 10:55 PM

I've had several people compliment the sound. I've also see people turn around to see what just went by as I downshift.
