What made you choose this particular product?
After doing a good deal of research on different mufflers, and running into Summit Racing Equipment's video on Flowmaster exhaust series comparison video, I decided on this Super HushPower 2 muffler, which ended up being the right choice!
What were you trying to accomplish by adding this product?
My old exhaust system was rusting out (but not severely), so I thought it would be a nice project to get rid of it in favor of a lighter, better-sounding custom setup. I wanted something very sporty, but not aggressive, or too loud.
Was it easy install? Any installation tips that will help others?
Mostly yes because this part of the exhaust project was easier to put up with than the glasspack--both before and after making changes. This one was a bolt-on both times. It is secured with v-bands in case I want to swap it out, or remove it easier when I want to do something in the rear, such as dropping the rear subframe, for example.
Once you’ve had a chance to use the product, did it meet your expectations?
At first, my expectations were rather mixed. It was a bit louder than I expected before installing the glasspack, and the raspiness was more of a thing before I rearranged the exhaust to have the muffler closer to the rear. Moving it to the rear gave it the more preferred low-tone, "burbling" exhaust note I was looking for, but either way, it always sounded good--especially with a glasspack. I was even told by a few people that it sounded like a V10, noticing how similar 5-cylinder and V10 engines sound!
Any additional comments?
Definitely a nice, lightweight, and not-too-loud option for custom exhausts! It is on the quieter-end of the Flowmaster exhaust aggressiveness spectrum after all.

What made you choose this particular product?
Loudest axlebacks in the market for the 3V with out compromising the "muscle car" sound.
What were you trying to accomplish by adding this product?
Make my car louder.
Was it easy install? Any installation tips that will help others?
Install was easy to do with the car lifted on ramps in my driveway.
Once you’ve had a chance to use the product, did it meet your expectations?
Met all my expectations.
Any additional comments?
I absolutely love this axlebacks and would recommend them to any 3V owner.
