Getting ready to purchase exhaust. I love the sound of the SLP LMs, and the Flowmaster American Thunders.

Anyone know what their HP gains were with either?

Thanks.

Your not going to get any noticable gains from any cat back. The stock mufflers are good for power they are just quiet.

You'll notice a big difference in the low end, but nothing at all above 3000 RPM. If you like the old school feel of low end torque, you'll love ANY aftermarket axle-back kit.

As far as gains, you're not going to get much with an axle back system. More important is choosing one that SOUNDS the way you want it to. The performance gain is minimal.
