First Borla Cat-Back Install on a 370Z

Mr_Z

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..

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.
