"exhaust was easy to install and all hardware was included." posted by: bluebike on August 21, 2011

"Installed in 1 1/2 hours by myself. Perfect fit. Sounds a little beefier at higher RPM's - I have a V10, so i think the noise will be unique anyway. Wish it had a little more rumble..." posted by: JB2.0 on July 1, 2008

"Sounds great! Not too loud but gives my truck a voice finally. After about 1500 miles its starting to be more noticeable. Very happy with product. Just make sure ur muffler isnt too rotted ( like mine) to where u have to weld on a piece of pipe to attach kit." posted by: poolman on August 7, 2013

"The muffler, pipes, hangers and clamps are all well engineered and seem to be high quality. It only took 30 minutes to install once the old muffler and tailpipe were out of the way. The Flowmaster 50 has more of a rumble than the stock muffler. If you want quieter you may want to look at their 70 series." posted by: Old Dakota on October 3, 2012

"Install went GREAT. After install I went to a local shop and had them seal weld all the joints just to complete the system. The one clamp at the rear of the muffler was stubborn and didn't want to tighten enough to secure the system from rotating. I might have been able to keep wrenching on it, but my plan was to have it welded anyway. The system sounds GREAT!!!" posted by: Inventor on April 1, 2012 view all 5 reviews

"This exhaust system was by far the best system that I have installed. If you are changing from single exhaust to dual. you'll be amazed! When Bolting the additional pipe, the exhaust system came with the right size bolt to go through the frame. When you get this no matter what vehicle, you will not have any issues!" posted by: FoXman92085 on July 6, 2009

If you have a performance vehicle, one of the best things that you can do for it is to install a performance exhaust system, such as a Flowmaster exhaust system. Flowmaster exhaust systems are available for a wide range of cars and trucks, and they come in several different series. Flowmaster 40,50, and 70 exhaust systems are designed for very powerful cars and trucks, and they are particularly suited for muscle cars. The Flowmaster 60 series exhaust system is one of the most versatile Flowmaster exhaust systems available, and it fits on a range of vehicles from compact cars all the way up to trucks. The Flowmaster 80 series exhaust system is designed for transversely mounted exhaust vehicles or those that require greater ground clearance. No matter what type of Flowmaster exhaust system you choose, it is manufactured out of tough and durable 16 gauge anodized steel and mig-welded for the sturdiest construction. Flowmaster exhaust systems are designed to flow freely, allowing you to generate the maximum amount of power from your engine. The deep and powerful sound of all Flowmaster exhaust systems sounds simply amazing and may be their best trait, despite all the power that can be wrung from them. Motor hobbyists should certainly get superb service while purchasing reliable auto parts. That's why we established an always-online technical assistance call bureau to answer all your requests. To make a good deal even better, all parts come with 100% free shipping for all orders more than $50. If you find a better price, give us a call - we will meet or beat any advertised price for auto parts.

Your car's exhaust system is responsible for letting harmful gases flow out of your vehicle. Aside from keeping the car's system clean of combustion-produced gas, it also provides your desired sound. However, not all exhaust system brands can offer you superb performance matched with a great sound at the same time. So to give you an idea on which brand to select, here's our short review of the Flowmaster exhaust system:

Flowmaster American Thunder exhaust system features:

  • It readily enhances performance, sound, and MPG right after installation.
  • It comes as a direct fit; it's custom-made for your specific year, make, and model vehicle.
  • It's made of large-diameter, mandrel-bent pipes.
  • It's available in dual-exit, split-rear design.
  • It uses a single inlet and a dual outlet muffler configuration.
  • It has the capacity to moderate sound level.
  • It comes with dual polished, stainless steel tubes measuring 2.5 inches each.
  • It's suited for vehicles with single-flanged catalytic converter.
  • It's offered with mounting hardware included.
  • It's backed by a three-year Flowmaster limited warranty.

We tried the Flowmaster American Thunder exhaust system on our 2007 Ford Ranger, and came up with these observations:

The wins

  • The installation is a breeze; being a direct fit surely speeds up the installation.
  • It's made of aluminized steel, allowing it to resist corrosion better than plain steel.
  • It comes in a natural finish for a neat and clean look.
  • Being 50-state legal allows you to drive to any state without worrying about getting a ticket.
  • It improves acceleration and offers passing power.
  • There's a considerable increase in fuel mileage.
  • It gives our truck an aggressive exhaust tone.

The loses

  • It's a bit costly, especially for DIYers. Other exhaust system series from Flowmaster are cheaper such as Flowmaster Force II and Hushpower Diesel.
  • Its three-year warranty is shorter compared to its stainless steel counterpart, which is covered by a limited lifetime warranty.

The scorecard

Getting the right exhaust system for your truck depends on your vehicle application. Usually, performance exhaust systems, like the Flowmaster American Thunder, costs higher than the standard exhaust systems. However, these exhaust systems would be your best bet if you want to achieve superior performance, deep sounds, and an increased MPG. The Flowmaster American Thunder is capable of improving your truck's performance as shown in our test drive. So if you're willing to go for the gold while enhancing your fuel mileage, then try this product.
