Chris Duke shows you how to improve the performance of your 2008 Ford Mustang GT by installing a MagnaFlow cat-back exhaust system.
The part number we installed is 15883 from MagnaFlow Performance Exhaust: V8 4.6L GAS 2.5in System, Magnapak Mufflers, Performance Tuned; Aggressive Tone, dual rear exit. For dyno information on this specific exhaust, click here. For installation instructions, click here.
Over a year and 29 episodes ago, Motorz TV started with a pilot episode where we installed a MagnaFlow exhaust on our project Ford F-150 pickup truck. Man, a lot has changed since then. It was called “Truckblog TV” back then, a spinoff concept based on my truck blog called Truckblog.com.
I was asked by MagnaFlow to write an article for Truckblog, much like I have been doing for the past 10 years or so. I had been thinking about trying a video install format for a while, and so Jason and I just went for it–the first episode of MOTORZ TV was born. That pilot also happens to be the only episode where we published a written install as well, available at Truckblog (and the only episode where I wear shorts and a t-shirt!)
Watch episode #1 and then watch this new episode (#29) and you’ll see how far we’ve come over the past year!
As for installation, it’s pretty simple. Jack up your car (or put it on a lift) and remove the old exhaust, then put on the new one. We really had to jack our Mustang up high in order to put the new over-the-axle pipes on, which is why I highly recommend (twice in this episode) to take your vehicle to a shop and use a lift. It’s mainly a safety concern… you have to lift it extremely high so if you do attempt it at home, be sure to secure the front with wheel blocks, and use strong jack stands, and just be very very careful. Some exhausts come in three sections (like the F-150 install), but this Mustang exhaust is only in two parts which increases the difficulty level of the install.
One part of the install that can be very time consuming is the alignment. The Mustang has two exhaust cutouts in the bumper for the tips to sit just right. In order to align them you have to make sure that all your bolts are loose, then align the tip… tighten, align, tighten, etc. It can be quite a struggle, so just be sure to take your time… just when you think it’s not going to fit, you wiggle or bang a pipe just right and it settles into place–right where you want it!
