High flow cats....
 

So I'm wanting to put some high flow cats on the truck but I'm getting so confused about what to get. Since I have never really looked when under my truck, I'm assuming mine has 4 cats since it is an 05. So.... 4 O2 sensors? When I go to a 2 cat setup where do the sensors all go? Also can I use magnaflow #94106 cat? Seen on a post that someone got them really cheap here http://www.performancepeddler.com/de...CT_ID=MAG94106 and the special still works. Any ideas or thoughts are appreciated.

I've got an 05 with the MagnaFlow #94106's. Mine only had 2 cats. But up front the stock sensors should be long enough to reach the rear (towards back of truck) of the cat.

Use this too.. Performance Peddler Promo: clubgp


What is the setup your going to run... ?

True duals? SI/DO.. SI/SO

I've already got a SI/DO magnaflow setup just looking for a bit more volume.

Ahh thats cool man. I had a SI/DO setup and then went to my current setup True Duals with High Flows, X-Pipe, DynoMax Bullets, to 45'd tips.. and MAN, it's been a crazy improvement on sound and performance over my old Flowmaster setup.

Not sure how much gain your going to receive doing just high flows but I haven't seen any videos or heard people talk much about that. If you got the cash, I would strongly suggest looking into true duals

Not the greatest video but you can get an idea of how mine sounds

I may have to check into it. just sucks going from exhaust setup to exhaust setup trying to find what you want. lol I have seen that a lot of people on here run the dynomax bullets though, possibly more that magnaflows, so there has to be something to them thats worth putting on.

All I can say is just watch a LOT of youtube video's to try and get an idea of what you want... Lot of good setups out there. Most of them start off as True Duals, but you can achieve a good setup goign with a 3" after the Y to the muffler if you want to stay with SI/DO.

Look up videos for DynoMax Bullets, MagnaPacks, Borla XR-1's
