Ok so I want my truck a little louder but I dont want it to sound like sh1t.

I think I am going to remove the secondary cats but I dont know what the bes way to go about this or how to trick the o2 so the cel will not come on. I dont know know a thing about this so if you guys could give me some pointers that would be cool. I read the thread before this and apparently that guy did something wrong. I know have a flowmaster 40 on it and plan on keeping that. I it to still sound deep but louder and not raspy and cracky.

You don't need to trick it, just have bungs welded on to the replacement B-pipe for the O2 sensors. If you don't want a raspy sound, then you should replace the 2nd cats with a straight-through resonator. I used a Dynomax bullet style muffler.

do you think that the place that is doing this for me will have the bungs that you speak of. and you dont think that my flowmaster will sound good?

They should, but I bought mine from Summit and took them to the shop. I don't think it'll sound good with straight B-pipes. I had a Flowmaster 70 with the OEM resonators removed and replaced with straight pipe. It sounded like crap; popped, crackled, etc. Had some custom B-pipes welded up with Dynomax bullet mufflers (resonators) inline, it sounds much much better.
