Exhaust Upgrade Question (Banks vs. MBRP)

[ClaryvilleF250]

Was wondering if anyone could help me here. I've got an '06 F250 powerstroke & I've been debating wheter to get a 4" Banks turbo back exhuast system (& leave my catalytic converter) or the 5" MBRP straight pipe system (which involves removing my catalytic converter). Two quesitons, (1) which system is better for adding HP & increasing fuel mileage and (2) does my truck have oxygen sensors past the converter, causing my Check Engine light to remain on if I were to remove my converter? If so how do I solve this problem. Any help would be appreciated. My truck is completely stock right now & I'm looking to start installing modifications to better fuel mileage & HP, as I'm only getting 14.5 mpg right now.

both systems are going to do about the same but the straight pipe will sound better and give you less restriction... either way i think you should go MBRP over banks.. unless your getting a way better deal with banks (usually always on the high side priced)

as far as future mods i would def get some gauges first then the custom tuned SCT afterwards...

if you need any other info or prices feel free to ask

I myself just put on the MBRP performance series turbo back kit. It is the offroad kit that deletes the cat and muffler. I love it and at 260 bucks you cant beat it. It fit good and had it installed by myself and a sawzall in 2 hours. I got mine at xtreme diesel but other sell it. It sounds killer! Honestly not too loud until your above half throttle then look the f*@# out! It sounds like a jet at idle but cruisin down the highway its hardly noticable. This is a 4inch kit. Honestly if your trucks stock and your not pushin 600 hp I wouldnt get a 5 incher anyhow unless you just abolutly want a five inch.

I had the Banks kit on my truck for over a year and then got borred at work one day and picked up two peices of 4" pipe at the local muffle shop. Then I cut my cat and muffler off and welded the two peices in. I like the straid pipe way better, the sound is great at WOT sounds like a pissed off V-8. Also it don't get near as mutch black coal from my tune.

I have a stainless banks monster exhaust turbo back, with cat and muffler and I think it sounds great. I don't like an obnoxious exhaust as it gets annoying after a while. The banks still roars with the cat and muff when I get on it, sounds sweet!! sounds like this 6.0.

MBRP is good to from what I've heard.

That MBRP has no cat... sounds good. Has muffler, but our DMV here inspected trucks for cats. Not to mention cops...

I went with the MBRP straight pipe stack kit and i love the sound of it.

You could put the cat on a diet and clean it out.
I have a banks and it has been good and sounds great without a cat and Erics X-street it barks at WOT.

Just get whichever you can get cheaper. If I'm not mistaken the MBRP just has a "test pipe" that is extra that replaces the cat, you should have no problem swapping the cat in or out of the system.

Both are good exhaust systems, but Banks always seems to be overpriced with everything.
