i have a 03 gt sra with 4:10 gear and new mac catback im looked to trade for 99-04 irs. let me know what you got. i will do the swap if you come to me it will take about 4 hours to complete the swap.
This may be worth a drive from FL to SC...My irs has lowering springs for the rear and also upgraded bushings in the center so wheel hop is not happening for me....I drive there and shouldnt be a problem ? I too also have a Mac catback but 3" but dont have tips on because one got scratched
