I personally like the exhaust, but it is no where near nesessary for the power you want. I would use stock 2.3t parts. The low HP doesnt make enough exhaust pressure to be efficient with the turbo. If you were flowing 400hp worth of exhaust through it it would be worth the investment. If you do buy that kit make sure you specify the spring you want, i didnt and got a 6PSI spring for the waste gate.
