Will get some WOT sound clips hopefully today!

This is the most perfect setup and exactly how I would have done it! I bet it sounds damn great!
With the windows all the way up, if you tap the throttle a bit from let's say something like a stop sign do you still hear a nice deep growl in the cabin?

You here a good growl/low tone....but no drone or rasp....love it!! Ithink with all new Stainless piping it will sound even better....my OEM exhaust has a ton of cuts in it!

Can you please take a video of the cold start?? My cold start is brutally loud with no mufflers and I want to know if the ultra quiets fix that.

Sounds awesome by the way!

How did you find someone willing to replace secondary cats w resonators?
We dont have emissions in fl but having trouble finding a shop after 3 shops.
I have downpipes n oem piping and just want to get rid of rasp.
WIll there be no rasp w dp & resonators instead of cats or should I keep cats n do resonators after x pipe?
Thanks

Just tell them it's a track car, there will be no rasp & no drone.

If what rob said doesnt work the other method is to remove the stock mid pipe and take it to the exhaust shop and have them do it. Its not illegal if its not on the car.

I did this with my mustang, had the 4 cats removed and dummies welded in. I couldnt find any shop that would do it, but one gave me a tip and said bring it in without the car and its legal for them to do since they could tell whom ever requested it was for offroad purposes which is why it wasn't on a car.

Keep looking, I had no problem finding one first try. They even bought the secondary cats from me making the swap only about $20

Any vids of WOT or a drive by with more revs? I've been gathering ideas for a custom exhaust and like what you have going.

I will get one of WOT in a few days...waiting on rims

R.G. · 10-21-2013, 10:18 PM

Hey Rob

Great thread. I'm basically getting the same set up done. Waiting on my super quite resonaters to come in to replace mufflers. Did you happen to get the drive by vids?

Not yet...I need to LOL!

R.G. · 10-21-2013, 10:22 PM

Haha
Gotcha
No worries man. Much appreciation for the thread. I'll get some up after my install. Only difference is I have high flow secondary cats. Car smokes like chimney without them

TT3 iN NyC · 10-22-2013, 08:18 AM

I currently have the Vanguard Exhaust with AR catless dp's and tons of drone/rasp. Would replacing the Vanguard resonators with the ultra quiet ones make any difference? It is recommended?

straightcashhomie · 03-19-2015, 06:53 AM

im bumping this out of the dead... but thoughts on how this would sound on an e92?

SgtGoldy · 05-31-2015, 08:33 PM

Rob is your second setup as loud as your first?
