Flowmaster American Thunder NPP Reviews?
Would anyone who has this setup care to offer their opinions, as far as sound, build quality/fitment, drone, variance with valves open/closed? I've seen mixed reviews on this forum and would like to see what more people think.

I've had it on for a month or so and I love it. To your points:
Sound: 10/10 Loud with a nice, deep rumble - exactly what I wanted. Inside with the windows up I could still use a little "more" but that's really a comment on how well insulated our cabins are. Build quality/fitment: 9/10 Very good quality, feels study and well made. Everything lined up perfectly during install. The black paint on the mufflers and pipes chips off easily though. The packaging gets a 1/10 though. Took multiple replacements before I got a set that didn't have damaged tips. Even now my set isn't 100% flawless. It's a problem on Flowmaster's end and not FedEx/UPS as the box doesn't have near enough padding and the tips are pushed right up against the edge of the box. It's unacceptable and I would almost recommend against buying them until they can confirm this is sorted out. Drone: 8/10 No drone, but it's not completely silent either. I can still hold a conversation with the valves in track mode. Occasionally I'll get a little rattle or reverberation at low speeds. Variance with valves open/closed: With the valves closed it's actually very tame. Closed is too quiet for me, so I only close them when I'm coming or going late at night so I don't disturb the neighbors. You may have seen this is in the other thread but here's my video: https://youtu.be/P8IsEk6sO38 Last edited by MXSG; 05-10-2017 at 10:40 AM. Reason: Video link |

Thanks for the opinions on the Flowmaster axle back , do you think you could pick up anything with the Flowmaster X pipe both in sound and performance?

I have the Flowmaster x-pipe with secondary cat delete. It's slightly louder and more raspy. I would say it has negligible effect on performance.

Thanks for your input. I'm definitely leaning towards going with this setup.

What is different is compared to the stock NPP in sound. I love my NPP...

How's the install going, can't wait to see videos. I think I'm going to pull trigger on this system but just need to confirm one more time. I had the Borla S-Type with mid pipes picked out but wanted something a little deeper, and then I saw the flowmasters and I think this is it.

If you don't mind me asking, who did you purchase them through?
