I may check ptv clearance and order some 1.65 rockers to increase my lift. I only have 520/540 lift now. I've been debating on taking my tailpipes off before the axle as well. I have 3.5 inch collectors into a 3 inch x pipe with 3 inch pipe all the way to the back. I have my performer rpm off now and I did a complete port job on it - still going to get a single plane to test back to back at the track next year once my converter is in.
