When i had the flowmaster muffler installed i noticed a huge increase in horsepower and my gas mileage went up to 17-18 around town. This muffler gives the 318 a nice throaty sound and is not loud from the inside of the truck. I would totally buy this muffler again its well worth it

Own a 2000 Jeep grand cherokee 4.7L v8, with full three inch exhuast from the Y-pipe back, high flow cat and previously a Flowmaster 70. I was looking for something louder than the 70 but not annoyingly loud. The 40 has a very nice deep sound yet isn't a drumming noise on the inside of the vehicle when travelling on the highway. Aggressive and deep sound when you want it to be, yet mellow enough to not drive you and your passengers crazy. Excellent muffler.

Super 40 dual in/out on my Tundra is enough sound, not obnoxious. My Delta 40 on a Dodge Hemi had deeper bellow, but louder idle. Flowmasters chart says Super is louder than Delta, so I was apprehensive, but wanted the dual in/out achieved with the Super. Don't know difference in 2 trucks, but the Tundra’s near stock at idle. On the gas is genuine Flowmaster, minimal cab noise. Flowmaster’s experts agreed with my selection. They’re happy assisting you finding best application for your truck.

I purchased this muffler recently and i love it. It was easy enough to install with a leangth of straight pipe to adapt to my old tailpipe and welding it all in. At first it was not as loud as i was expecting but after about a week breaking it in, it sounds great! I would recomend this to anyone who is looking to have their truck sound mean! The super 40 has that loud, deep, throaty sound that flowmaster claims. It makes my 03 Silverado 1500, 4.8L-V8 sound BA even though it is still a small-block. The drone inside the cab is not to bad except at about 50 to 55 when on the gas. No chance yet to do the math on weather or not it actually improves gas mileage but i have noticed a slight increase in power and torque.

Went with the single in dual out on my 2010 Silverado 5.3 and 3" Flowmaster tips and this thing rumbles! Very deep powerful tone. My truck is 100% stock and this makes all the difference. Interior sound is very throaty and powerful but not loud. Can easily be blocked out with music or even opening the windows a bit will drown out some sound. If someone inside the car is talking it will be louder than the exhaust, don't worry. From the outside it's very aggressive. May not be as loud as some would like. If you're looking for anything louder go for Cherrybombs or a cutout. Other than that this thing rumbles! On my 2010 Silverado 5.3 it sounds good even at high revs in neutral. Doesn't pop or crack. Very solid sound.

This muffler was perfect for my 98 Tacoma and my own needs. It has the deep, tone I was after, but without being annoyingly loud and "God I wish I was cool, but I'm not, so I'll rev my 9 colored civic up to 6 grand before shifting into second through a school zone in hopes of raising my self-esteem" sounding. I have the muffler mounted mainly under the bed, and the interior noise is only a couple DB's louder than stock. It's great. I gained a lot of top end and some bottom end. It makes up for most of the shifting gaps. I'd definately purchase again. AutoAnything also provided excellent service; I'll look here first for all of my car needs.
