has anyone heard Flowmaster's American Thunder Cat-Back kit for 2009 Dodge Challenger 5.7L Hemi. i like loud. But i do like the corsa setup even tho i think i t will be more quiet. however the flowmaster is half the cost of the corsa. i have flows on my duster and i love the sound.

I know a number of folks who bought the FlowMaster system weren't pleased with the drone at highway speed, nor the fit of the system.

I just installed the Corsa catback system on my SRT8 yesterday. Yup, it's quiet when you want it quiet, and obnoxious when you mash the throttle down. The fit was excellent and only took minor fussing with to get the tips to line up correctly. The sound is excellent too.
Granted, the Corsa system is pricey, but if you shop around for the best deal (and look for "online discount codes"), bargains can be found.
My Corsa cat-back system cost me $1,169.10, including S&H. I thought that was a very good deal.
:D

Forgot to mention, the Corsa 14138 Cat Back system for the SRT8's was $1,299.00 at http://www.streetsideauto.com/ . If you enter coupon code "SSAWINNER09", you get another 10% off, bringing the final price to $1,169.10. They FedEx shipped mine - standard - and the system I ordered last Monday night was on my front steps last Wednesday morning - 36 hours later. (I've seen this system retail for over $1,700.00 at some "famous" race parts shops.)
Awesome!

I ordered magnaflow competition series 16515. i love the look and the sound. there is a website, planetmagnaflow.com where you can enter "your price." they can match it or shoot you a quote. i think i got them to around $800.

Do they make Zoomers for the 2017 Challenger R/T?
