I loved the name Borla, but bought the Stinger exhaust which was supposedly an easy bolt on exhaust.WELL, it was a nightmnare of an install. The bends were wrong, collars didn't fit, hangers weren't in the right spots,and one of the tips was facing 10 oclock, when it should of been at 12 oclock. the only way to make it look right is to cut it off and reweld it. This was the worst install the muffler shop has ever seen,especially being a Borla, I expected much bettr. Took 8 hours to install and make it fit, and luckily they only charged me 4 hours labor. I want satisfaction from Borla. I would like half of my install money back due to their negligence. 1 star rating

It was time for my 2003 Mustang GT to get a replacement cat back. First the packaging was great no damage and the tips were wrapped. The install was straightforward and took about 2 hours...a little tweaks were needed at the tips to get them the same height.The sound after install was great, they are not over the top loud but they changed the sound low tones. Overall great upgrade.

I must say this is the best investment I ve done on my mustang so far...to start with it came perfectly wrapped in foam,so no chance of damage,so presentation was good(5 point),i went and got it professionally fitted,it took about an hour to remove the old factory exhaust(which had to be cut out ) and this was installed with ease,so fitting was also good(5 point),then finally I fired up the V 8 and voila music to my ears,this is a perfectly balanced exhaust system not overly loud like some of the other brands and not so docile,does not have any humming or rattling sound like some of the other brands just clear deep bass so the car feels like a V 10 and I do believe there is a significant amount of house power increase as well.I generally listen to the radio when I m driving,but since I've Installed Borla(stingers), i just listen to the engine sound,I really wanted this exhaust for a long while but it was too way out of budget until i saw it on amazon,the 4 inch polished tips look awesome/agressive and finally i would like to conclude by saying thank you Borla for an amazing exhaust system and thank you amazon for an amazing price ;)

This exhaust system is the best catback exhaust system I have heard on a Mustang and I have been around many. The sound rumbles and the bubbling sound after you let off the pedal sounds phenomenal from inside and outside. Sounds crisp and deep when accelerating at any level but is almost unnoticeable at highway cruising speeds between 45-60mph. Would never think about replacing this system for any other, as it replaced my flowmaster setup. Perfect system with no drone.Check out my video comparison on Youtube to hear the sound![...]

This exhaust sounds amazing on my 2001 Mustang GT!!! I really wanted this system, but it was so expensive on the other sites I was looking at, so I was just going to settle with another brand. When I found this system on Amazon for so cheap, almost $200 less than on the other Mustang site I was looking at, I purchased it immediately. It took my fiance and I only 1.5 hours to remove the old exhaust and bolt this one up. It brings a big grin to my face every time I start my car, and every time I rev her. Plus the 4" polished tips look awesome coming out the back. This was an amazing product for an amazing price. Thank you Amazon!!

I recently purchased the Borla Stinger Catback, it arrived fast and was packaged well also. Fit is very good, install was pretty straight forward. The only thing I didn't care for is how it connects to the midpipe, its got a six inch section of 2 1/4" dia. adapter pipe thats similar to a header collector reducer that the main catback slides onto and clamps to instead of being solid all the way forward. They were buried in the foam packing material and hard to find initially. Other than that it looks great, I love the big rolled tips and the sound is fantastic, there maybe some hp gains too. It gets loud inside the car on the hwy. at 80 mph though, forget about talking on cell phone in that situation.
