About this product

Charles Smith

2013 Dodge Charger

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.

What made you choose this particular product?

Other exhaust clips with this muffler on the 2.4L engine. I preffered a custom dual exhaust with two of these over pre made catbacks.

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

First!!!

Jake Bishop

2015 Ford Mustang

What made you choose this particular product?

Had a friend at a automotive shop that took it off a customers car and was going to throw it away, so I was offered it for $100.

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

Yes. I was actually looking at Gibson exhaust but I couldn't pass up the deal.

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

Easy install. Cutting is required on the factory exhaust and it's a little awkward to remove the stock exhaust by yourself.

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

It's loud and drones some but with a manual you can keep the rpm in the right range to avoid this. Sounds great, almost like a VQ from a 350Z/370Z but a little raspier.

Skylar Reid

2000 Chevrolet Camaro

Any additional comments?

Stock exhaust, cut a 12in section off after the cats which are gutted. Love the sound, love the look of the exhaust tips so 90% of the exhaust is still intact.
