...Between leaving all 4 cats or deleting the rear 2. Doing true duals as soon as my x-pipe comes in the mail. Is there any gain performance wise by deleting the rear 2 or does one do it to gain sound quality or quantity? If there's gain on all levels well then, good.

 

If you want a loud, deep and agressive exhaust system, delete the rear 2 cats. are you going to be running any type of muffler? ex. bullet, magnapack etc..? if so, true duals with an x pipe and the rear cats deleted will sound amazing imo.
Heres what this setup will sound like if you run dynomax bullets:

The setup in your video before the swap is almost identical to my future setup. Except I'll be running twin 14" magnaflows and different tips protruding straight out under the bumper. That's an excellent clip, I almost wish I had seen it before I made my purchase. Those bullets sound damn good.

 

Oh yea...BTW you convinced me to delete the rear 2.

 

That video isn't mine, its DarrenWS6's. I only used it to show you what your setup would sound like. just wanted to clear that up lol.

haha I knew it wouldnt take much once you saw that video. I think 14" magnaflows will sound great also, but they might be as loud as you want. But, Good Luck and enjoy the drop in MPG's once you hear it!
P.S. Welcome to the site

 

Lol i sure will! It's all getting installed this wednesday Ill try to get some sort of sound clip. Thanks for the welcome!

 

yeah darrens exhaust was what made me wanna change from that stock stuff i had on mine. i think everyone should delete 2 out of 4 cats.

 

^ Do you have a sound clip or video?
