Borla axle back exhaust revving. (L99)

Here is the video. Sorry for the quality it was done at night and on my iphone. The strange part is the car would not let us go over 4k RPM...very strange.

Video and sound is actually good for a phone.

On an LS3 6M, the issue you have with the rpm not going over 4000 is related to 'comp mode.' if you have an LS3 and you were in 'comp mode,' the rpm's would be limited to 4000 awaiting your launch. Not sure about the L99 cars, maybe others can comment.

It felt almost like a launch control but the car is an auto.

[QUOTE=Indpowr;796607]Here is the video. Sorry for the quality it was done at night and on my iphone. The strange part is the car would not let us go over 4k RPM...very strange.

The reason for that is the L99 has the Rev Limiter set to 4000 RPM in the tune for Park and Neutral. Everything else is set to 6200 RPM. Don't know about the LS3, but if it does it too it is probably set the same. It can be tuned out when tuned if desired. Just FYI.

Wich Borla is that? I think they have a few axel back versions. It sounds nice I was consiering Borla but it may be a little tame for me

its incredible how much quieter is sounds on the L99 with that center muffler. I have the s type axle back and its louder since the LS3 does not have the center muffler. sometimes i think its too loud though....

with an axle back that may be correct however with a full system you dont have that extra resonator and its much louder. I dislike that dam extra resonator lol I guess its for the AFM BS.
