Borla Exhaust Review! - BMW 3-Series (E90 E92) Forum

Mr. 5 · 05-11-2008, 01:15 AM

A while back, I had the idea to come up with my own exhaust instead of paying a bunch of money for something else.
I cut out up my stock exhaust and added Magnaflow parts here and there.

It was a pretty good idea, but lately I've been going for a different sound.

Thanks to Harold from HP Autowerks and Borla, I finally received the sound that I was looking for.
I was thinking of the way that the Borla muffler is constructed and it made so much sense to me how they really might be able acheive a "back and forth" sound; kind of like the sounds of the V8s where the scavange back and forth.
Borla uses a single muffler in the rear instead of 2 different mufflers.
The single muffler is pretty much a resonated X pipe where the exhaust gases combine just before the exiting point.

The exhaust is very deep, yet does not drone one bit in my manual. Some have said that the exhaust is too quiet. I dont' understand what they want, but maybe my catless DPs are helping.

In the videos, you can here the back and forth gurgle, especially when I let my foot off the gas and leave it in gear. The sound is just beautiful!
I am extremely happy!

So, my exhaust is in the following configuration:

Ultimate Racing Catless Downpipes
High Flow Cats in the place of the OEM secondaries
Borla Exhaust

Let me know what you guys think.

Nice write up. I may have missed it but is it just the Borla exhaust, with no 2ndary cats delete?

Robert · 05-11-2008, 01:49 AM

What if some kid walks by and pick up the camera?

Contact HP Autowerks. They are having a really good sale right now. Retail is something like 1300 and the are much lower.

Mr. 5 · 05-11-2008, 09:36 AM

Hopefully you can tell when I'm just cruising when compared to the WOT flybys.

HP Autowerks · 05-12-2008, 06:30 PM

Great write up and your car sounds great!

ybbiz34 · 06-08-2008, 11:11 AM

Hmmm, it seems that all of the talk I have seen on here about the Borla exhaust has been positive.

It's the route I decided to go, getting it installed this weekend..

billspreston · 06-08-2008, 01:15 PM

That sounds just like my setup (Borla + RR DPs) - I love it! Yours is a bit louder with the HFC secondaries - sounds great dude! Surprised you don't drone at all though, I still get a bit around 2.5k

Borla w/ RR DPs video:

Sniz · 06-08-2008, 01:38 PM

beautiful video ^^ great video quality, but the sound quality doesn't seem to be quite as good. Regardless car looks great.

ybbiz34 · 06-08-2008, 01:48 PM
