Here's a quick video that we threw together to show off the new Borla axle back exhaust. It sounds great and the low growl it has matches the mean look the 1M gives off.
We paired it with the Mad Dad mid pipe which is already available; the fitment is great.
The Borla Prototype should be available sometime shortly after the first of the year.
The green and blue lines represents the 1M with stock mid-pipe and muffler. Black and red with Mad Dad mip-pipe and Borla prototype muffler. Max gain is about 15 hp and 15+ ft/lb. We can see most of the gains are in the mid to higher rpm range so we know the stock system is not bad in lower rpm with lower exhaust flow, but can be a bottleneck once the flow demand goes up.
Current mods are GIAC Stage 1, AFE Stage 2 closed intake and ER CP. ETC FMIC is next...We will then report back on the gains.
