I'm very close to turboing my car now, and have another question. I recently discovered the Kteller 2.5" DP for the td04-15G greddy kit. If I were to go with a full mandrel bent 2.5" exhaust(with a high flow cat) and that DP how much would that really improve flow and hp over the standard 2" DP and a 2.25" crush bent exhaust(with the stock cat). I plan to redo the exhaust eventually with 2.5" mandrel bent eventually, but just wondering if it's worth it whp wise for crunch my budget a little. I only plan to make about 160-175whp on my setup (d16z6, 15G, JRC6" @ 5-7PSI) and know that a bigger exhaust can help but since I'm on a slight budget, just really want to know if it's worth it o squeeze the cost in there.

EDIT:
screw it I'm doing it everyone I've talked to said it'll be an incredible difference
