- first post - What are the main differences between these two? Is the borla louder or does it just have a more high pitch than ultra racing? If so is the lower end of the ultra racing still a reasonable volume? Been trying to decide based off of YT videos lol.

I have a 2017 Mazda 3 2.0L and just installed the borla axle back exhaust. What should my next step be with regards to the exhaust system? MagnaFlow has a high flow catalytic converter can I replace my with this one? Also read some people adding mid pipe in place of the catalytic converter...

Just purchased a jet black 2019 mazda 3 hatch, my first mazda, and it has been so much fun! I plan on doing some performance modifications and really having some fun with it. I’m curious if the 2014-2018 Mazda 3 exhaust is identical or routed the same and I could just buy the 2014-2018 Borla...

Hello! Just got a 2019 mazda 3 hatch and i’m curious if anyone knows if the 2014-2018 Borla exhaust is compatible with the 2019 Mazda 3 hatch? The routing looked the same when I looked at the exhaust but I’m wondering if anyone knows for certain.

I absolutely love the gorgeous sound this exhaust makes, I live in Northern California. LMK of any hints or if anyone is selling one!

I installed the borla s-type exhaust on my 2018 and noticed that there's a slight gap where the exhaust flange is. I've tightened the bolts down probably tighter than they should be but that seems to be the only way to get rid of the gap. Anyone else experience this issue?

Hello all, I am looking to buy the Borla exhaust for my 2016 Mazda 3 SGT, but I can not find anyone who has installed the exhaust with oem black rear diffuser for the hatchback. Does it fit or will I melt the rear diffuser. Someone let my know. I contacted Borla they could not give me a good...

I am a new owner of a snowflake white 2017 mazda 3 hatchback 2.0 and was wondering if anyone in the walton county area had either of the exhausts stated in the title that I could come hear in person! I am also willing to drive to ATL if anyone around there has one.

Hey guys, So I installed the CS hangers for my exhaust, and the tech guy noticed that my exhaust tips were not straight, the left sticks out more than the right, also the hangers in the left is a little bit more diagonal than the one in the right which is straight, here are some pics that...

I'm getting rid of my car and put everything back to stock. I just put the springs on last week and they literally have 50 miles on them. Borla system has been on for probably 7k miles or so. Exhaust is gone. Make me an offer on the springs. Need them out of the garage. Must pay...

I am selling my Borla exhaust from a 2016 Mazda3. It sounds really nice. It's not too loud, but you can definitely hear the engine compared to the stock muffler. I recently sold the car so I don't need this anymore. Exhaust was on the car for only ~7k miles. It was on a 2.5L engine Mazda3, but...

Hey everyone, I have a 2016 Mazda 3 2.5L sport GT hatchback and wanted to get your input on a few things!! I'm getting a tune that is going to let me have full control of my gears in manual paddle shifting mode instead of them automatically shifting when I redline (which I am SO excited for)...

Hello everyone, I want to install a Borla 11918 S-Type Axle-Back Exhaust System for my 2017 mazda 3 sedan, Now, it says it 's for 5 door hatch back in the 'fits these' section, but I'm wondering if it would still fit the sedan. Only thing I'm worried about is the rear bumper is cut for the...

This thread is an extension of the one in this link. I figure folks wouldn't think to check that thread for a sound clip. Here it is:

After too much research, I've decided on the Borla Axle-Back exhaust. On their site they list a number of online retailers. I've read mixed reviews on all of them and was wondering if there's a go-to for most folks or any that I should definitely stay away from. JEGS High Performance Auto...

Hey everyone I've finally made the decision to finally upgrade my exhaust on my 2017 GT hatch. I've dug around forums looking at exhaust options and I've narrowed it down to 3: Borla, UR, and corksport. (all axle back) I've looked around the forums hoping there would be more comparisons on the...

2016 3, 2.0, Borla exhaust, no tune yet. A few external rev sounds as well as a pretty good 2nd gear pull interior clip taken with the windows up so you can hear what it actually sounds like to the driver. Like anything, listening on a computer or otherwise through worth a damn speakers will...
