I have a flowmaster Super 44, single in / dual out with 5''x18'' in tips!
I'm thinking about taking out the cats??? Good idea???
I have heard TONS of different advice from friends; most of which have NO CLUE what they are talkin about......
What are ALL of the effects??? (Good and Bad!)
Thanks guys,
Clint

 

do you have a video of how your exhaust sounds?

 

if you cut out the cats you'll get a cel and fuel mileage will drop. you can get a tuner to turn out the cel. you'll lose bottom end torque. i'd at least put in 2 high flows. and sell your old cats to a scrap yard for some money.

 

Yea your best option would probably be to scrap the old cats and replace them with hi flows. You can get the 9" Maggie flows for 50 bucks on performance peddler, and you should make some money selling the old ones.

 

click my youtube in my sig and watch my video i dont have any cats.

 

it wont sound all that great. Keep it with cats, if anything just get hi-flows.

 

Sounds Badd-***!
What did it do to your Gas Mileage, Low-end torque, and overall power?

 

Friend did it right as i got it so not really sure but low end torque and power was all taking care of by a superchip programmer and a cold air intake. With my bigger tires, exhaust, superchip, and cold air intake im avg about 13.5 mpg

 

Sounds good! I just got mine taken out and it sounds AWESOME! No CEL yet!

 

sweet can you get a video clip?

 

I will be able to soon. I'm gettin my bigger tips put on this week. I'll try to after that!

 

5x18 tips aren't big enough..? Hope your truck is lifted then.

 

My badd... Not bigger, just new and different! They are still 5"x18", but I have regular round tips now, I'm puttin Slash cuts on!

 

Mhockey, is your setup true duals or just one flowmaster dualed out?


did your truck have 4 cats when you got it and you just cut off the rear 2 or what?

 

Flowmaster 40 y pipe to the muffler and dual exit from the muffler to 3 1/2 X 18 Angled tips i have some pics. All cats taken out
