I bought Meattooth's Magnaflow from him last week; it's the one that he had for sale on here that he bought to use as a pattern for his 2-1/2" system. When it arrived, I sprayed the muffler with some flat black BBQ paint to "hide" it better; kind of a shame to paint over polished stainless steel.
Yesterday after work, I pulled it into my dad's workshop (since his floor is a lot flatter than mine), drove the front up onto ramps, and jacked up the rear and put it on jackstands.
Next, I crawled underneath to give everything a quick survey and get the layout straight in my head.
First, I cut the over axle pipe right in front of the rear suspension, using this tool that I bought from AutoZone (IIRC) like 15 years ago. It's a lifesaver for doing exhaust work in tight places because you only need to turn it about 90 degrees to cut through a pipe.
There wasn't quite enough room to remove the muffler assembly with just the one cut, so I grabbed the Sawzall and hacked the pipe off right before the muffler, and pulled the muffler off. I found it easier to remove the muffler hangers from the unibody, then pull the rubber hangers off--it was only 2 easily accessible bolts per side.
Next, I removed the crossmember in the middle of the car by removing 2 bolts. I used a Sharpie marker to mark the orientation of the crossmember for reinstallation later. Lastly, I used the exhaust cutter to cut the pipe 3" behind the cat, per Magnaflow's instructions.
Here is the OE carnage:
I mocked-up the muffler to see how the tips were going to fit with the lower valence; no trimming necessary, though I wish it tucked better-- I personally wouldn't mind trimming a bit of plastic if it meant the tips didn't hang so low.
The only real issue that I had with the install was fitting the "over axle" pipe. Had I been using a lift, it probably wouldn't have been an issue, but I just didin't have room to snake the pipe into place. I was finally able to gain enough clearance by removing a plastic shroud beneath the rear door that is covering up brake lines and what-not. Removed 3 screws, dropped the panel, and voila, the necessary clearance.
Once the over axle pipe was secured in the rubber hangers, I slipped a clamp over each end of the resonator pipe, slipped one end onto the stub behind the cat, and the other onto the over axle pipe. Also reinstalled the plastic shroud.
I slipped the third clamp onto the muffler pipe, then made the final connection with the over axle pipe.
Once I was certain that there was plenty of clearance (at least 1/2") around all of the pipes, I tightened the clamps, starting at the cat and working my way toward the muffler. Lastly, I reinstalled the crossmember.
Once I was sure everything was out from under the car, I jacked up the rear, and removed the jackstands.
Moment of truth: "Push to Start" VROOOOM,VROOOOMMMMAAA, VROOOOMMMMAAA!!!
Held a rag tightly over the tips to listen for exhaust leaks, picked up all of my tools, then had some fun on the 30 mile trip home!
Sound clip from Magnaflow's website:
Overall, a very well-made system, and aside from the one hiccup, a very straight-forward installation. If you have access to a vehicle lift, use one, but it can be installed farly easilly with ramps and jackstands. From start to finish, the install took me about 2 hours to complete, including several Gatorade breaks. I would whole-heartedly recommend this system to anybody who doesn't want an overly loud or agressive exhaust. To me and my 46 year old ears, it sounds about perfect--it has a nice, tuned tone to it, not at all "ricey", when you get it up around 5K, it sounds really nice, and absolutely no drone at all.
