Hate how quiet my 15 sho is. I dont like corsa nor will i spend that kind of money. Im looking for louder then stock. Little deep growl without rasp or drone. Thinking of just adding the dynomax  mufflers or keeping stock mufflers and doing xpipe with 3rd cat and resonator delete. Any input?
 
Here is my thread on the rasp from hell with the Corsa Exhaust & Stainless Works Downpipes.

After the troubles I have been having with my downpipes and exhaust... I would strongly suggest just catless downpipes. This is a V6 and it will have some level of rice but its WAY to raspy with the setup I chose.
 
I have a stock exhaust with catless 3" downpipes.

It definitely has a beefier tone to it at idle but at cruise it is not noticeable.

When I get on it there is a little rasp but worth the extra power.

The turbos are more noticeable as a bonus.
 
Shoman has a video here somewhere with just dynamax mufflers.  He has them installed with band clamps so he can go back to stock for road trips.
 
I have the dynomax mufflers with a 3rd cat/resonator delete. Getting downpipes eventually. I had my local muffler shop install some adapters on my stock mufflers so I can easily swap between them within 15-20 minutes. Love the sound of my exhaust, lots of compliments, just lots of drone. Great for cruising around town, not for road trips. Like I said though, 15 minutes and it can be super quiet so it's a nice compromise for me.
