borla is deep but on the quiet side unless you straight pipe teh first can.

Here you can see the full system and can spot the two clamps that hold the exhaust to the downpipes:

I had the rear <a href="http://images8.fotki.com/v124/photos/4/43687/1492850/IMG_0469Small-vi.jpg">resonator removed</a> in favor of straight 3" pipe...

Now <b>that</b> sounds aggressive!!!<ul><li><a href="http://public.fotki.com/LI-S4/cars_and_stuff/mods/s4_exhaust_ii/">More Pics...</a></li></ul>

You get any droning out of the Borla? I thought a few reported some droning.

scrape. And I know a couple people who have exhaust leak from where the clamp is.

..if you you ask the right people, you just may get what you ask for!

I told the fabricator "I want a very throaty, mildly louder exhaust...now do what you want"

And they did. Came out great!

If you remove the center resonator you will drone to no end..removing the rear is much more forgiving.

If you have a Borla already, I'd be willing to sell you the rear section on mine. It bolts in in about fifteen minutes. I want to change the tips...exact same setup but with different tips.
