5great exhaust system
By camokid06
This product arrived on time and eveything was in the kit. I put this on my 2007 toyota fj cruiser. It gives the vehicle a deeper/louder tone than the stock exhaust.

4Great Addition!
By Louie B
Great pipe! Has a good mellow tone and ads some deep thunder to the quiet sound of the OEM. Not overwhelming as some of the Flowmaster pipes can be. I heard one on another FJ and decided to go with it having tried other exhaust manufacturers products. This was installed on a 2007 Toyota FJ Cruiser. From the get go you feel and increase in power and the most important part is the MPG you will gain out of it.

4Good for the price.
By Philip
Not the greatest fitment, but I was able to make it work. Comes with light duty clamps, which is lame. Generally good sound, but a little too much at WOT. Some resonance, but only at WOT, so it's ok. Flange bell flare on the collector is a little generously sized compared to OEM, so I initially had a small leak at the collector. Clamping bosses on the polished outlet are placed poorly, making them easily visible from the rear of the vehicle. Only one retaining washer was provided, and there should be four.I have been using Flowmaster exhaust systems for about 15 years, and this one is consistent with the ones from vehicles past. They are either perfect, as was the exhaust for my '12 Challenger, or they are quirky like this one for my '13 FJ. Overall this is a good system, but don't be shocked if you have to Mc'Gyver up some solutions. I would suggest that you plan on acquiring some real clamps right from the jump.
