going by memory, I think I have a flowmaster ( I drove the Audi to work today), how do you think your Borla matches up with the flowmaster, noise-wise?

Well, I'm going from memory too...Originally Posted by Joe Isuzu
But as I remember it, the Flowmeister had a deeper, more rumblier (is that even a word?) sound than the Borla.
While the Borla has kind of a rough/raspy (not ricey) sound under hard acceleration, it has a fairly quiet demeanor at cruising speeds, meanng, I hardly notice the exhaust note at highway & cruising around town speeds.
Hope this is helping, & not making the waters more muddy...

You can also play with sound by the size of your pipes after the muffler.
2.25" is probably typical. 2.5" makes it a bit louder, 2.0" would make it a bit softer.
Also watch out for resonance - it varies with the vehicle not the muffler. So I would recommend a muffler that has baffles AND glass packing.

Let's put it this way, if I keep the tach around 2k or less, the flowmaster is fine, above that it's loud and at WOT it's really loud, which judging by some of the posts here is what some people are really wanting! (hint hint, there will be a very gently used flowmaster for sale soon here)Well, I'm going from memory too...

Driving through the neighbourhood, leaving a stoplight, driving at cruising speeds, all of this I want to barely hear the muffler, once again, a little louder than oem is ok, when I'm goosing it, then yea, it's ok to hear some noise, I just don't want to hear it 90% of the time
The Borla customer service people were stating a turbo muffler would likely work, you remember if that's what you have?
Super VXer
Yep, it's a turbo.
If you check my profile, the model # is in there.
I experimented with a Supertrapp tip for a while, but eventually went with the perforated cone insert in the tip to knock a few dB off.
I found that at http://store.summitracing.com/partde...5&autoview=sku

great, appreciate the input LDub!, looking forward to checking it out later, need to get back to work

My two cents...
Flowmasters are really loud - you may be shocked at first. I certainly was when I put my Flowmaster 50 Delta in with 2.5" piping. It softened up as it filled with carbon, though, but it is still very loud from 1/3 throttle on up (I feel Joe's pain!). The idle burble is awesome-sounding, though!
I think Kenny is dead-on in his assessment - it gets loud in back. Some sound deadening in the back of the VX should go with an exhaust upgrade (one of my summer projects).
But if you upsize your piping and go with an "unpacked" muffler like the Flowmaster, you will notice a difference in power. It's not hp you're gaining (those come at higher rpm), it's lb-ft of torque off idle that you gain with the less-restrictive exhaust, and I noticed it immediately as I pulled out of the muffler shop when it was all done. I went from chirping the rears inside tire to chirping both the front and rear inside tires.
Good luck!

I have two layers of RAAMmat and two layers of ensolite in the back- so much so that my panels don't fit all that right anymore back there. It made little difference in exhaust noise but knocked down the road noise and improved the sound system.
