I probably mentioned this in prior posts, but I am now living in Kansas City, and the Cougar is finally here with me. One of the things that has been bothering me for a while is the change in the exhaust note. I think my old mufflers were getting blown out and the sound was just not pleasant and way too loud for my taste.
So a friend of a friend recommended a local place and I went to see them for a consultation. I knew that I wanted to keep the tailpipes and that I wanted an X-pipe. Recall that this exhaust had no crossover pipe of any kind. We discussed muffler type and brand. I wanted things quiet, but I also didn't want turbo mufflers. I personally think the tone of turbo mufflers is just no that appealing. We discussed Magnaflow, Flowmaster, DynoMax UltraFlow and a few others. I also knew that I wanted the biggest case muffler that can fit in the space. He didn't care because I was ordering the parts. I settled on the 20" case DynoMax UltraFlows.
I got home and started looking up the pricing and the UltraFlows were like $120 each. That got me thinking about Borla ProXS mufflers, so I checked their website. Turns out they have 19" case mufflers and they were $15 cheaper. I ordered the Borla mufflers, Magnaflow x-pipe and a pair of Jegs brand v-band clamps.
Here are some in process pictures of the installation.
These are the old pipes from the manifolds to the mufflers.

Final installation with both tailpipes attached.
I am very pleased with the installation and the sound. It is super mellow at idle, but starts to get a little volume around 2000RPM. It has a nice deep tone and the exhaust note is greatly smoothed out, not doubt because of the x-pipe. I am also pretty sure that the x-pipe added a good bit of torque below 2500rpm.
I have video clips of the sound posted on my Instagram account.
