I installed a Flowmaster 17139 American Thunder exhaust system earlier this summer. That kit comes with Flowmaster Super 44 mufflers that have a pretty aggressive sound. Some people I know really like the sound of the car with that system on it...But, I'm not so crazy about it. It drones a lot at idle inside, and it's a bit loud for my taste. It's not the loudest thing on the road...but just isn't fitting my style.

I was thinking of switching to quieter mufflers. I did some looking around online and came across some Borla 40653 mufflers and I'm wondering if those would be a bit better. Anyone have any experience with those? Any other suggestions?

I like the throaty low rumble sound at idle and low RPM, but am just looking for a more subtle sound than these Flowmaster Super 44's.

The system is 2.5" from the headers back.

Check the Jim Hand book if you have one. He lists a bunch of mufflers that he likes and the Dba of each along with flow rates.

I'm a fan of the Goerlich Xcellerator muffler - great flow and sound in my opinion, but well mannered at idle. I have them on my vert.
