What made you choose this particular product?

Quality and familiarity with sound.

Is this your first time buying from this brand? Did you consider other brands?

Was it easy to install? Any installation tips that will help others?

A little cumbersome on the garage floor, but very straight forward and fairly simple (exception of left side fixed bolt bracket from existing pro chamber :o ).

Once you've had a chance to use the product, did it meet your expectations?

Yes.

Any additional comments?

I sought a sound change toward something a little less aggressive. I never knew what exactly the existing cat back brand was. They were (well, I still have them in the garage) quality built, but very aggressive,, maybe 1 chamber in each muffler albeit thin. The sound went from a rabid crackle to a now lower tone rumble. Aggressive cam sound with the stroke and metallic courtesy sound from headers are all still there. ;)

What made you choose this particular product?

This product gives you that fantastic and aggressive sound you expect out of a muscle car. Highly recommend for anyone who wants to add a bit of growl to their ride!

Is this your first time buying from this brand? Did you consider other brands?

This is my first time buying from Flowmaster and I considered corsa as an alternative before settling on the Flowmasters.

Was it easy to install? Any installation tips that will help others?

I had them professionally installed.

Once you've had a chance to use the product, did it meet your expectations?

They sounded exactly how I wanted them to sound. I was overjoyed!

Any additional comments?

They do drone a bit during MDS activation and in the 2.2k rpm range. I would recommend 12inch cherry bomb glasspack mufflers to use in place of the resonators to tone down the drone while maintaining the impressive sound. Your mileage and preferences may vary.
