Review & Install Video
You should check out the Flowmaster Outlaw cat-back if you're looking for a budget-friendly, stainless steel cat-back that's going to be loud. The cat-back features the Outlaw mufflers, which are known to deliver on sound, and they're some of the most affordable on the site at this time. When it comes to the install, you can expect this to take [you] an hour or two, and it's going to be a one out of three wrenches on the difficulty meter. Sound is going to be one of the most important things here when it comes to this system, and the Outlaw mufflers are race-oriented mufflers that are more resonator tubes than actual mufflers. These produce a sound that has a low decibel, but it rumbles and has a good amount of volume to it. Even though these are race-style mufflers, Flowmaster does tune the mufflers, so you're not just going to get a ton of noise. The tuned sound means that you'll get a good, controlled sound on the outside of the car, and little to no drone in the interior, which will be nice for those daily drivers. This cat-back doesn't produce a high-pitched raspy sound. It does have some popping on the decel note, so you're not looking at a flat sound. Overall, I'd rate this cat-back as a four out of five on the loudness scale, with one being a quiet upgrade and five being a very loud upgrade. Now, just make sure you keep in mind that if you ever change your headers or your mid-pipe down the road, this could open up even more noise for you. As far as materials, you're looking at 409 stainless steel for the majority of this system here, and 304 stainless steel tips. The fact that the tips are stainless steel means that they're going to keep that nice polished look to them, even over time. The entire cat-back is mandrel-bent, and it's two and a half-inch most of the way. So it'll bolt right up to your factory mid-pipe. The mufflers, which are coated black, have a three-inch diameter, and the tips are four-inch. Price-wise, you can expect to pay just over the $600 mark for this cat-back. This isn't the least expensive option out there, but it is one of the most affordable, especially when it comes to stainless steel options. If you're really on a budget, though, Pypes does make the Pype Bomb Super System, that's loud like this cat-back is, for about $50 less. This is a direct bolt-on item, so you're looking at a very easy install. I'm going to call this a one out of three wrenches on the scale when we look at difficulty. Overall, you're looking at about one hour to get this all done. A lift would certainly make things easier for you here, but the job can be done on jack stands as well, if you don't have access to one. All that you're really going to need is a socket set when it comes to tools. This cat-back will come with new hangers and all new clamps for you, so no need to transfer over anything from your stock exhaust. The whole cat-back can be dropped as one big piece, so an extra set of hands can really help here. When you go to install your new setup, it very simply bolts right up into the stock location, so you won't have to cut or modify anything. It'll probably be easiest to leave everything loose until you have it all lined up, and then tighten it down. That's going to be it for the Flowmaster Outlaw cat-back exhaust, fitting the 2005 through 2010 GT and GT500. But you can check it out more online right here at americanmuscle.com.
