cat-back system

[RibbeRacing85]

i am looking into getting an exhaust system for my 05 6.0L. i really want to find the loudest cat-back system on the market. if anyone can help me out that would be great. if getting a turbo back system is going to be a lot louder then let me know what your opinion is on those to. thanks

I would get a turbo back exhaust system that retains the cat. Then get a cat delete test pipe. That way you can take the cat off and put it back on.

I agree. I used the MBRP stuff with the delete pipes and was very pleased with the sound.

Goose350 has the right idea..if you plan to retain the cat with the exhuast system you may as well leave it stock, as the cat is the biggest restriction of our exhuast system.

My signature has a video clip of MBRP turbo back with cat delete pipe right after i installed it

Turbo back cat delete. MBRP. Unless you have emissions to deal with then you wont want to tamper with the cat.....Good Luck

MBRP is definitely the way to go in this situation. If you want the 4" turbo back that retains the cat, get the S6206 series. If you want 5", its the S6234 series of kits. We have both setups on our site, let me know if I can help with anything.

I have a magna flow, however, if you looking for loud, it's not much different from stock. I agree with the above posts, get a turbo back, with a cat delete pipe.

with the system that retains the cat do you still get good tone and turbo whistle?

typically what people do is get the system that retains the cat, then get a cate delete pipe, so the exhuast system is free flowing, but you will always have the option to reinstall the cat anytime its needed, unlike the "offroad" version's, they dont have the option to reinstall the cat.

As I said before the cat is the biggest restriction of our exhaust system, if you are doing a cat back exhaust or a turbo back and leaving the cat installed, don't even waste the money on the exhaust upgrade.
