yea.. 18psi shouldnt be making a noise like that over 4k with WOT... id definatley do a leakdown test just to make sure. You can do one yourself if you have the right parts (air compressor, gauge, pvc cap with adapter). You can make one provided you have an air compressor.. maybe $15/20 bucks at home depot for the rest. If not, then try a local performance shop, but idk what they'll charge. I've heard anywhere from $35 to $55 bucks for a leakdown. If you are modding then invest in a compressor or make the pvc cap and borrow a compressor
. Its a good test to do every once in a while and after every mod dealing with intake and exhaust parts! You can search google for leakdown procedures or find a thread here! Good luck Boss. Hope its nothing big time!
