This sucker is loud!
I ordered the Magnaflow Pro-Series on 31 July 2019. Estimated shipping was 2-5 business days. Shipped on 1 Aug, received it on 6 Aug. The tracking number didn’t work so I didn’t know when it was going to arrive.
I worked on my removing my exhaust on 5 Aug (my only day off this week) and took me a bit of time. The nuts on the old muffler looked like a cone. Couldn’t even get a rounded nut extractor to grip it. Had to drop my pan. That has all its other challenges of having rusted bolts and holding the trans up. I finally had access to the nut but I’d be a monkey’s uncle if it was not welded on! So I had to cut it with a reciprocating saw. After I got that taken cared of, I had to cut the pipe as I can’t get it over the axle as I’m laying down under a vehicle on jack stands. So if you’re planning on doing this install, take a look at your old exhaust to see what problems it would give you taking them off.
I received the cat back exhaust the next day in a neatly packaged box. Looking it over, it looks like a really nicely put together round muffler. Welds were nicely even and smooth. The brand name is stamped on two sides. The exhaust tip looks like an after thought. Just some angled down pipe with rough sharp edges. I guess it does matter as no one can see it. But I do wish they at least buffed out the edges.
Earlier in the day, I had purchased some exhaust flange nuts (m10 x 1.5) to replace the one that I’m supposed to reuse. The nut size would have been useful if added on the item information. Better yet, magnaflow should include these two nuts.
Installation was straight forward. Align the studs with the cat flange and loosely tighten the nuts. Install the exhaust tip on the hanger and line up the muffler and use the clamp to loosely hold them together. Once everything lines up tighten the nuts down at the flange. Btw, make sure you have a 15mm deep socket, the studs are long so a normal socket will be too shallow. Then tighten up the clamp.
The test drive. When I first started my TJ in my garage, there was a very deep rumble that echoed inside the cabin. It was quite loud probably because I was still in the garage. When I backed out the tone was a nice and deep. When I started to go forward, man I can tell this is going to be loud. Not obnoxious loud but yes your neighbors will hear you loud. Sort of like taking out the baffle out of your Harley exhaust. When I got to the main road, the sound was definitely awesome going through the gears! It’s like a totally new experience.
Overall I’m very happy with this cat back exhaust system. Just a word of caution, if you don’t want it loud, don’t buy this. Lol
