Flowmaster v6 exhaust
So i just purchased flowmaster 409 s American thunder axle back for my 2015 2lt rs v6 will it have drone or rasp sound and i know it will not sound like a v8. Will i need a resonated x pipe to cut any drone or rasp with this set up or will a x pipe just help it sound better. Anyone with the American thunder set up have any advice or comments (suggestions or opions welcome). Let me know what u guys think, thanks.

i started off with a muffler delete and the drone was bad so i put on flowmaster 40's and regular x pipe. at that time the drone was noticeable but not too bad and it sounded decent. i got new tips and had everything redone so i took out the resonators. two times the noise and a lot more drone, so i added the resonated x pipe and that's my current set up. almost every exhaust set up will require the x pipe to tone down the drone, and almost everyone on here will tell you that. throw the flowmasters on, if it has drone throw a resonated x pipe and you should be good

Ok thanks for the reply i have no idea if the American thunder set up will have drone or rasp, but i am way to old to deal with a lot of racket, lol. Was just wondering if anybody else is running the same set up and could tell me if i just need to go ahead and have the resonated x pipe put on when i have the mufflers installed. If so i was just going to order one and have it all installed at the same time. Stock set up is just to blah for me, but i don't want to mess up the sound of the american thunder set up if it doesn't need the resonated x pipe. Looking for a kind of smooth exotic car sound.

Ok guys thanks for the advice will probably just do the mufflers first, then go from there don't want to order a x pipe and not need it and be stuck with it.

Kicking myself for not knowing i could have probaly found a car with npp exhaust, which is what i really want but i want a fully functional set up. And that would be a huge pita to find all the parts for and would cost like hell probably.

I got the dynomax 'valvetech' VT series axle back system. It ran about 400 a couple years back. The valves are spring loaded and open under the pressure of moderate to hard acceleration and allow the exhaust to pass straight through without going through the baffle of the muffler. Works great. Nice and loud when the valve opens up, sounds real nice at startup, and zero drone at constant or highway speed. I love it!

Ok thanks Kenny but i already ordered the flowmasters and like i said i am not looking for really loud as i am older not looking for loud fart can sounding. And i am looking for smooth but a little louder than stock, no it will never sound near as good as a v8 and besides i don't want to piss off the neighborhood either.

So how do you like the sound of the FM 409's? Assuming you have them on. John |

Just got around to having them installed last Friday still trying to decide if i am going to add the resonated x pipe. Has some drone when engine loads up around 1700 rpms. Need to put my rotofab cai on and see how it sounds with that added. Cold start is awesome nice rumble at first is deeper tone than stock but i want to drive it some to season the exhaust some and see if the drone goes away. I probably will wind up having the x pipe installed to smooth it out i never intended for it to be loud, just wanted a better sound than stock. To old for loud and droney and don't want anything like a fart can tone either, can't ride around with it pegged to the floor all the time even though it sings a sweet tone under acceleration.

bdd8401-ok thanks
Me, I ended up going with the magnaflows, the shop said they could do it today at a good price. He did our 6.0 Silverado I had awhile back with Magnaflow. He did good work but man that was droney, think it might of been due to the crew cab and the muffler placement being under the cab. The Camaro is good now, I just had to drown out that 3.6 litre sewing machine noise, lol. Cold start sounds good, throaty. has a decent sound when I want it to move. Best of all is when I'm just cruising I don't have this constant hum resonating through-out the interior. I think if I spent more money, cat backs and all I would have a better sound but for the money spent now, this is really good, I'm happy. Wife may have liked it a bit louder. BTW, my Camaro is a convertible, not sure if that would make a difference inside or not. I'm like you tho, wouldn't have mattered if I went with FM or MF I just didn't want that LOUD "motorcycle noise" so to speak. John Last edited by Rupkin2; 03-30-2017 at 08:14 AM. |
