Hey guys... Just put on a 5 inch exhaust, turbo back. Sounds great by the way! But after install, I have low boost now. before it was like 20-25psi. Seen 28psi on a WOT run before the exhaust. Only thing changed was the exhaust. Now it's only 15-16 max!. Any idea why it's so low? No exhaust leaks either.
