I’ve heard the Pro XS mufflers are very good with little to no drone. I’ll be trying them this year since my mangaflows are starting to drone

Im going back to a non resonated Hpipe to the NPP mufflers. The x is nice but i dont get high speeds often so ill take the lower gain and deeper tone instead

i got the magnaflow and to be honest i don't think it's much louder than stock i don't notice any drone. i am running factory cats and exhaust manifolds. i like it but i would not pay full MSRP for it i only got it because it cost me 500 bucks almost new off a guy that wrecked his car.i am not a cat or "muffler delete" kind of guy.if i had headers and not cats it would sound totally different.

For everyone else, it makes a world of difference having big long tubes, no cats and needing 3 inch diameter piping. Not easy to get that system quiet. I’ll politely say no thanks to the 2.5 inch cat backs, or comparing npp with stock manifolds.

I didn't have rasp with my flowmaster mufflers, setup was just really loud. But if you do, I think the magnaflow will take care of it nicely. |

Update
Took me long enough but I finally got the magnaflow resonated x pipe in. We managed to squeeze the large one in there, I forgot what it measured, but it is the lowest point now, and sometimes scrapes over speed bumps.
It lost a little bit of rasp and toned it down a good bit. I'd still prefer it more quiet.

Sounds like the neighbors should be alright with that. I know start up is probably still loud though. You dont have a daily for those early morning trips? lol

I do, company car. Plus the wife’s Grand Cherokee. It still has a little bit of raspy farty sound, but much better. Nothing like a chambered muffler tho. U cant have it all.

SLP Powerflo if you can find them. Super deep and tame-ish with headers and no cats

trying to kill drone on a 3” system is tough and it seems to be even more difficult to sell the 3” catback lol

I go back to work in person tomorrow morning. Which means I have to cold start my cammed, long tubed, x-pipe/catless, Flowmaster Outlawed monster at 5:45 am. The Outlaw mufflers are almost as loud as straight pipes. I am already cringing thinking about having to do this and wake the entire neighborhood up. I hate just jumping in the car and taking off, but I may find a side road a little away from the house to let it warm up. Since cam install/Covid started I have made a habit of not starting the car before 9am or after 10pm. That's out the window now.

I replaced everything except the NPP mufflers and put them on a switch so I can run them full closed in the morning.
