although i have yet to drive my 2+2 with the chip (got it when i lost my license) i wasnt planning on buying it if i had to pay full price. i got a deal on a used one, soi snagged it. but i had exhaust, then exhuast and intake without a chip, and no problems. thats whatmost na'ers do. just make sure to reset the stock ecu when you put the exhuast on.
