Cat back vs Turbo back Exhaust

[Vip]

Right now I have a cat back 4" straight pipe on my truck. I was wondering if there is much difference in performance or noise between that and running 4" from the turbo back?

I'm trying to gain a little more turbo noise and if it'll reduce EGT's that's just a side benefit.

Is the cat still on the truck or is it deleted?

The Cat is still on the truck, starting after the cat it is a staight 4" run to the rear.

Order a cat delete pipe you will be fine.

Turbo back will give you more turbo noise, and probably lower EGT's(more free flowing). As long as you not in a state that has emission testing. I run a 4" turbo back MBRP with a 5" tip and like it...Good Luck....Steve

So I am runnin a 4" magnaflow system from downpipe back with no kitty and a magnaflow muffler. Would I stand to gain anything by removing the muffler and going straight out?

Going to the muffler shop after work to see what it'll cost to have them piece a cat-delete in there in the interest of $$$. Truck is bone stock and I won't be putting a serious tune on it any time soon so not sure running new 4" all the way up to the turbo will gain me much for the cost. Thanks for all the input -

You will gain some exhaust tone and turbo whistle. Thats about it

Thanks, Dave. Didn't know if the muffler was causing enough restriction to justify removing or not. Kinda like the way it sounds now. Thanks again.

Ended up removing the cat and replacing the down pipe with 4" so it's now a straight 4" from the turbo back. Love the sound!
