looking into mufflers, and found some really cheap thrush mufflers, and flowmasters, anyone know how they sound on gtps?

im not doing a full exhaust considering i just got a new resonator 3 months ago, and the piping to the mufflers arent in bad shape, just the mufflers.

thanks
 


i have flow 40s on my car. with a big glasspack they sounded alright, but they drone like a mofo. i went back to a stock catback after i had these, so i dont have any opinons on much other mufflers. the only muffler i really liked on people's cars are borla, but they arent 'cheap' either.

as a whole, chambered mufflers sound like butt on our cars.
 
ya i was looking at thrush, i saw a bunch of glasspacks but not regular mufflers, so which ones are you talking about.

And i think every car with an exhuast has drone mustangs and GTOs do atleast.
 


I had minimal drone with my magnaflows but with no tips it got way worse so I thru a res back on it

The drone in my crown vic is way worse with thrushes dumped at the axle
 
I have a 3" downpipe with cat and stock catback with the mufflers replaced with flowmaster 40 series. I'm not sure where people get that these things sound like ass with them because I love the way it sounds. Yes it does drone a little but nothing that you wouldn't expect with replacing the mufflers for performance ones. I have the stock resonator but I wanted to change that out for something as well. Maybe a glass pack or maybe some whisper resonator from ZZP.
 
they get really raspy when you dont have a resonator/glasspack. having a cat helps too.

try those same mufflers with a full 2.5" catback and no resonator. they are loud.
 


BRIAN I BELIEVE is referring to me..... i have a 3 inch catless downpipe stock ressy with dual thrush mufflers and tweaked em a bit with a few pin holes in the baffles. :) sounds great i think. brian can vouch for me. "bwolf"

x2 except imo all v6s are somewhat raspy, unless you spend the money. thou i dont know much about exhaust, personally a 3" dp with the rest stock sounds good enough to me. never been a fan of cat backs on anything but v8s.
 
I just put Magnaflows on mine, and I really cant hear any difference. Sounds exactly the same as the factory exhaust.
