Before anyone says there isn't a y pipe included with the magnaflow system. I knew this before the purchase. Another titan site had an individual who had done a ton of dyno runs with different exhausts with his truck and the magnaflow had done the best with a cold air intake and stock exhaust manifolds.

Previously I swapped in a Aem Brute force intake and decided on a just swapping in a magnaflow muffler a 5 x 11 part number 12586. I found it to be slightly louder than stock but not excessive. It came to life when you step on it. I didn't like the fit after the muffler and decided to get it welded that was when I made the mistake. Had a friend weld it and he didn't notice that the tailpipe rotated when he took off the band clamp and was touching the spare, so I needed to replace the tailpipe since grinding or cutting the welds woldn't work. I was planning on just replacing the tailpipe but only found two places local that could mandral bend the pipe. One place was out of the pipe due to the size and the other one had a rude horses backside for a owner. Let's just say it's not worth getting into.

Decided on the magnaflow stainless system since I got it for 365.25 including delivery. Came in less than a week installed quickly. Instead of the 5 x 11 muffler it had a 5 x 8 and is louder by a bit. It's surprising that most people find the magnaflow exhaust system for the Titan one of the least loudest systems.

My impressions driving are that before the muffler swap I could hear the cold air intake sucking when I stepped on it. After the muffler swap I could slightly hear it but usually if I reached the point where it's loud the exhaust would overpower it. Slight drone with the muffler swap not bad thou. Didn't lose any bottom end at all and thought I might have picked up a little. That was important for me since I tow a large boat. With the exhaust swap it's much louder than the muffler swap was and I kind of expected to lose a little bottom end torque since back pressure was lost and the titan loves backpressure. But since the swap about 400 miles I've noticed a few times where I broke traction starting off at a light or stop sign. It seems to have picked up some bottom end torque or there's a increase somewhere on the bottom end that I haven't gotten used to. Slight drone more than the muffler swap. It's louder than I was hoping.

If your planning on using the truck, you can't beat a muffler swap. Not much louder than stock, but use U bolts and not band clamps if not welding. If you want to be one of those people that wants their truck noticed then the exhaust swap is good. It's a little over a 1/2" larger than stock from the muffler 3" over the previous 2.5". I haven't noticed a increase in fuel mileage since the swap at all and actually think I lost a little. More air going in. Also people want to race you.
