ToNew GM exhaust upgrade

[The Incredible Smurf]

I was checking out the price of the Borla (still $1800) and saw a new exhaust option. They claim and improvement of 13hp and 7 lbft tq where no such stat is given for the Borla. They are also charging $2400 for this version. Seems a steep premium over the already amazing Borla system. Anyone know what's up with these?

It peaks my curiosity for sure. However, even an official part, if there’s no mention of tuning after the install… the numbers mean nothing in my opinion. When descriptions use the words “up to” and “can”, that means only under specific conditions.

Bonus points for them saying it wont void warranty.

im thinking thats the GM engineered system.

Agreed on the 'up to' numbers. I doubt there's much between them on that count and not much realized without a tune.

It would be interesting to see if that's the dual mode exhaust and it can be retrofit on the '22s and '23s.

Most of the free flowing exhausts will increase HP/ torque, it's whether or not you notice 4 or 5 HP, which is a 1 % gain. Even if you get 8-10 HP, you might not feel it. Before and after dyno tests are the only way to know for sure.

I love my Borla system that I bought through GM. It’s a little loud when the motor is cold but other than that it’s perfect for me. Who needs a stereo with music like that.
