Product was a very simple and straightforward install. Took longer to remove factory unit due to rusty bolts. I really like the quality of the chrome tips. The sound is more subdued than expected, but seems to be getting a little more rumble with use. Only issue was that one of the pipe clamps stripped threads during installation. Was able to re thread and use part.

2005 Tundra Flowmaster Review

After searching for an aftermarket exhaust system, I decided to go with the Flowmaster Delta Flow 50 Series complete system package. This system comes with a drone. This system is such a better approach of an after market exhaust system than your small town muffler shop can offer. It would be a good idea to go to the Flowmaster web site and do some research to see what the benefits are VS just installing a muffler with your average pipes with bad welds. Autoanything has excellent prices as well.

Amazing Sound

sound amazing. I left the OE Y-pipe w/resonator in the system which gives my exhaust a nice hum. I would definitely recommend

Overall the installation went according to the plans, with exception to the flange hook up to the catalytic converter. the flange lip on the Flowmaster muffler was not large enough to allow the flange clamp to tighten properly, therefore unable to clamp this joint. The exhaust sound is very subdued not what I expected.

Love the sound

Pros - The ease in which to physically install the system was unbelievable. Everything fit as advertised. Cons - The instructions are incomplete and leave one to their imagination. It is obvious the folks who wrote the instructions are familiar with installing the system. Example - The instructions don't mention that you have to turn the rear hangers inward toward the spare tire to make them work or you should weld the system after it is installed. Welding is not needed.

Wow! What a difference on my 2002 Tundra

I installed this and an aFe Cold air intake at the same time. The sound of the Flowmaster exhaust is great! At idle it is actualy quiter than the stock exhaust was but when you get on it....IT SOUNDS GREAT! The two items together were a great upgrade to my Tundra. Added a ton of tourqe which is exactly what I was looking for. I pull a small cargo trailer full of tools to and from the job site. The trailer was starting to get so heavy the truck was struggling to tow it up hills....until now! Now I can barely even tell it is back there. The transmission hardly ever shifts into passing gear now with the cruise on. Before is was shifting into passing gear on almost every hill. AND I HAVE ALREADY SEEN ABOUT A 2 MPG INCREASE! and I have only had it installed for about 3 weeks. By the way, this is a single inlet muffler to dual out exits pipes. I have done a lot of research and have found out that the 4.7L Toyota engine loses power if you convert it to true duals.

Great

Inside at highway speed - a very low, barely noticeable hum. During normal acceleration - a comforting rumble. Punch it - you know it's there. Does seam to increase performance and m.p.g.. Flowmaster plus the K&N intake I put in earlier, together, make a solid performance increase and my Tundra soundslike the good old days and my 68 Barracuda S. I had my local shop weld the exhaust pipe joints. - Sarge

Perfect fit and sound

I am impressed with the fit and finish of the system on my Tundra. The kit comes with the option of either dual side or straight out the back and comes with stainless steel tips to finish it off. I went with the side exit and it looks better than a factory dual exhaust. The sound is perfect, not too loud and no interior drone.

I had to hacksaw off one bolt. That was the toughest part. Nice sound, real good increase in power. The exhaust tips look good. The kit comes with a resonater and a muffler, but attaches after the stock resonator, which stays on. I thought that was a little odd, having two resonators like that, but it works great.
