Not sure if you are asking the question I am about to answer however, its good info anyway
THe phrase "straight pipe" basically means someone took out the resonators, (first muffler looking things under the passenger compartment) and took out the stock muffler (out back) and ran a "straight pipe" all the way from the turbo outlet to the back of the car.
Basically this equates to no backpressure on the turbo (from exhaust stacking up in the muffler/resonators) and usually helps performance/fuel efficiency of the auto.
The cost of straight pipes? Noise+NOISE!
