I called muffler king today and they said for a flowmaster system, 2.5 in 2.25 out single in single out to a y split into two stainless tips would run $330. Does that sound about right because ive got a friend with a tundra who got a full si/do flowmaster setup for about 300, am i gettin ripped off?
And whats the best pipe size set up for the most power gain?

The standard for exhaust diameter is to not run too large of exhaust, for the engine needs a certain amount of backpressure. This is correct in the sense of one should not run too large of diameter exhaust tubing, but the statement of the engine needing backpressure is not. You need to have the least amount of backpressure possible to produce maximum power. Too large of diameter exhaust will cause a power loss and loss of low end torque because a larger pipe has less exhaust stream velocity than a smaller pipe. If the exhaust pipe is too large, then the exhaust flow will be slowed with less velocity.

heres no cats with a flowmaster 40 si/do 2 1/2" mandrel bent before, 2 1/4" after muffler to 3 1/2" stainless tips.
i paid 318 for a cat back and went back and paid 145 to get the cats off (4 of them). i talked to the guy and he liked me i guess so the first time he cut me a deal, then when i went back he seriously cut it back (charged my friend 200 to get his off)

^^^the o2 sensors had new holes drilled and i was going to get o2 simulators but the engine light hasnt come on so i have yet to get them. my do it one day just to make sure everythings alright.
and im pretty sure there was only one on my truck and i remember seeing it before the cats, wierd.

ur truck has 2 if not 3 o2 sensors because its OBD-2. the forward one is the upsteam to moniter engine efficency and always toggles to tweak the A/F ratio. the down stream o2 sensors are to moniter catalyst efficency and usually dont toggle much unless ur cat is fubar'd.
regardless u need the upstream o2 sensor, no if ands or buts about it. ur engine will run like **** or not run at all without it. the downstream o2s are not required but i wouldnt touch them.

"is the bulb burnt out? i would think that you truck wouldnt run very good like that."
I had mine out to change them this past weekend , I thought it might have been why my engine was ideling so pootly after I overheated.. Maybe carbons burned on them or something.. Sadly.. Without the sensors, It didn't want to idle at all.
Methinks they ( more or less ) have to be there or some type of simulator. I'm no OBDII pro, but I will see what happens this weekend when I finish what I'm doing. I have to change plugs and will be under there anyway.
