Just got my Flowmaster exhaust system on my 69 Camaro and all i can say is AWESOME! The quality parts and the instructions to put on were great. What an upgrade from the old system. Great Purchase!!

The quality of the muffler and piping was great. However, expect to either have someone weld it or find better clamps becasue the ones that come in this kit are terrible. You can tighten the clamp all the way down and still pull the pipe out.

I would recommend the Aggressive Flowmaster exhaust to everyone. I was kind of hesitant at first because I have a V6 Camaro and didn't know how it would sound. It sounds beefy like a V8 would and not to loud. Very easy to install.

Exhaust is a great value. Gives a nice rumble. There is some noise in the cab, but I like it. Not as aggressive sounding as I had hoped, but I'm sure after I get a tuner and my CAI I'll be very happy. Overall a nice exhaust!

Looks and sounds great. Had to cut 1/2 inch off tailpipe section to improve fit. Would not clear gastank skidplate. Came with wrong size clamps (2.25" vice 2.50"), but Flowmaster had then at my house the next day. Did notice an improvement in MPG along with the great sound.

AS always AutoAnything has provided Great service,shipping,value and information. But I feel flowmaster dropped the ball on their instruction and directions, the quality is great just a little more time to clarify some of the install notes and pictures would really help the novice. I installed this system alone in about 2 hours, I can see where someone with little mechanic knowledge would be stumped. The system is perfect, low rumble at an idle kickass when you want.

How loud is this system compared to other brands
Answered by Nathan S. — May 06, 2013 12:39 PM
Hi, It's less of a question of volume and more of a question of tone. Many of our brands offer different muffler and outlet styles to tailor sound levels to your liking.

What are the benefits between the two? I want to feel more power, hear more growl and get better HP out of my Dodge Ram.
Answered by Nathan S. — Jan 21, 2013 12:47 PM
Hi Andrew, Upgrading your exhaust system is definitely a good way to increase HP, torque, mileage and add a nice growl to your rig. Where space and installation simplicity permits, a Cat-Back system is used to replace the factory mufflers and tubing. Your Dodge is a perfect candidate for system like this, as the exhaust components are right out in the open for easy replacement. An Axle-Back system is found almost entirely in performance cars that compact exhaust systems, suspension and gas tanks into small areas, and is good alternative to hours of parts removal just to get all of the stock tubing out. Either style of exhaust increases performance by replacing the mufflers with high flow units, but the Cat-Back system holds and advantage as it replaces a larger portion of the restrictive factory tubing with smooth mandrel bends. And, if you have a cold air intake already installed on your truck, it will perform better with a cat-back system on the other end. One thing holds true for all engines regardless of size or brand: The more exhaust that exits an engine, the more efficiently fresh air can be drawn in, which equals more power.

I am looking to put an exhaust system on my 04 F-150 FX4 5.4L V8. I cant decide between the 40 series and the super 44. The louder the better. Also, with getting the super 44 would I have to buy the exhaust system and then buy the super 44 muffler separate. I cant seem to find a complete system for my truck with the super 44.

What is the benefit of getting the system from the cat back vs the axle back mufflers? Which series gives you a little more sound than the standard set up?
Answered by Nathan S. — Nov 08, 2012 4:03 PM
The factory tubing causes exhaust restriction as well, so a cat-back system tends to make a bit more power in most cases. Both kits give you a little more sound, it's going to be comparable.

I have been interested in getting a Flowmaster exhaust and have seen a lot of videos on youtube and love the sound but was wondering if these kits come with a resonator so I can better decide on what route I want to go with. I have been looking at getting 50 series Delta Flow but don't want the sound to loud in the cab.

1999 ranger 3.0 ffv. What approximate horsepower gains would there be with a Force II single side system? Already have K&N FIPK CAI.
Answered by Nathan S. — Aug 08, 2012 3:36 PM
It looks like we only offer the Flomaster American System in a dual exhaust for the 3.0L at the moment. You will see gains of approximately 8-12 hp with the Flowmaster system. You can also throw a programmer into the equation to maximize your Ranger's performance. Flowmaster Exhaust Superchips Programmer

The Flowmaster Force II system part # 817573 would be a great addition to your truck and for the best price around. The kit gives you the option to have the tailpipes exit behind the rear tires or under the bumper, allowing you to tune the sound of your truck and best of all, will increase your fuel mileage to the tune of 1-3 mpg depending on your driving style.

I think the American Thunder Dual Rear/Dual Side Exit System would be perfect for you. It can be set up as either a dual side or rear exit system and comes in aluminized or stainless construction.

I want to put a new exhaust system on but i recently got the code p0420 on my half ton 98 chevy and was wondering if a new flowmaster exhaust system would fix the cat converter or if i have to buy a new cat and then an exhaust system?
Answered by Nathan S. — Jun 20, 2012 8:39 AM 1995 Ford F-150
The exhaust system bolts on after the catalytic converter and will not fix your situation. The good news is that it could possibly be an oxygen sensor and not the catalytic converter. Possibly, the code means that a pre-cat oxygen sensor could be seeing something that the post-cat oxygen sensor is not, which would make the computer think that the catalytic converter is clogged when it may not be. An OBDII scanner usually wont tell you what the exact problem is, but it will point you in the right direction for further diagnosis.

When your engine goes into economy mode it still runs 2 cylinders from each bank. It will make the same sound, just not as loud.

I just installed on a 2011 Durango that shuts down to 4 cylinders and the sound is horrible! Sounds like a Neon on steroids. Has this horrible deep toned droning sound. Definetely does not sound like the beefy 8 cylinder Hemi!! This may not happen with your particular make/model but I recommend doing some research before investing this much time and money into something you will likely hate. All I can say is that this one will not be staying on my Durango.

forgive me but how do you connect a set of headers (ie JBA) to the for example, magnaflow exhaust? do bothe have flanges?
Answered by Joe S. — Mar 18, 2012 2:27 PM 2012 Nissan Frontier
Headers will connect to a down pipe which goes into a cat convertor and after the cat there is a flange that the catback system goes onto. For the headers, you will need piping (called a downpipe) to get you to either a testpipe (cat-less) or cat convertor, once again connecting through flanges.
