Exuast sizes

[SlammedAccord89]

I'm runnin a turbo setup, Im startin to put things together and I keep forgetting a key ingredient, exuast. I just need to know what size to use, I've heard anywhere from 2 1/2in. to 3in. Im goin ghetto and buyin a Summit muffler, I just need to know what size as well. I'm runnin a T3 turbo around 10-15 pounds of boost.

2.5" inch piping should suit your boost purposes, once you get above 15 psi, you might want to look into a little bigger.

If you don't have emissions(I can't remember if Florida has em or not) you can take out the cat, but be prepared for a lot of noise... then use a resonator to quiet it down.

Now if you listen to travis(ahem), it will be hella loud and not enjoyable to drive in for very long, and if you have emissions testing, you won't pass without the cat.
