After I got it home, taken about 2 feet away as opposed to 10 feet.

Great Look!!:)

To my untuned ear, there is no change in sound. Maybe if I had recorded before and after sounds, but honestly it sounds about the same. As for looks, completely worth it going from 3" to 4".

They are oval with the top "lip" extending about half an inch further than the bottom.

Racing Beat did a series of tests against the stock exhaust:
"Based upon our initial test sessions, it appeared that the Mazda engineers did not leave much "untapped" horsepower behind in the stock exhaust system. Although it appears there might be modest power gains available from a "cat-back" exhaust system, be wary of big horsepower claims from any aftermarket exhaust system.

Our testing has provided the following results:

Stock production engine - with muffler removed +5 HP
Stock production engine - with RB muffler + 3.5 HP
Stock production engine - with aftermarket system "A" muffler + 3.5 HP
Stock production engine - with aftermarket system "B" muffler + -1.5 HP"

I don't want to pay $800-1k more for 3.5HP, but leaving the tiny tips on wasn't really an option with my body kit anyway since it didnt match, so I went with the Borla exhaust tips.

they fit in well with your bumper.
Thanks :) Honestly it does look better in person, the pics are taken on my phone so the back end looks out of proportion.

^Although that may be true..The Borla sounds amazing, so know when your friends ask you if you have the Borla exhaust, you will have to say "No I only bought the tips to look good.."

I didn't buy it for my friends, I bought it for myself. Nobody knows what it's supposed to sound like anyway, but glad to hear you like the way your Borla exhaust sounds :-)

Yeah, I didn't buy my full exhaust for the HP gains N/A. I bought it for looks and sound. And now that I have a turbo kit, it will be of more benefit.

This is definitely on my list of things I am doing to my 8 as soon as I get it back from dealer. :icon_tup:

It looks alright! Is it welded on or is it clamped?

It's clamped & they welded it on in a couple places.
