Enjoy.
I agree with this statement 100%. My car is a 100% stock '89 930. I removed the stock exhaust and installed RarlyL8's exhaust, and it completely transformed the car's power. Boost comes in earlier, and much stronger. It also pulls well up through redline.

While the car is by no means a rocket, it is vastly better than it was with the stock exhaust... and it now sounds great as well.

But still... I'll be bolting in a 7200 and a B&B intercooler this weekend
