Goonz you NEED a flex pipe. You didn't have one before cos your car had a 2-bolt donut flex-flange. Having a fully rigid exhaust system is asking for broken headers AND/OR the studs holding the headers in. Order a 3-bolt flex and have it put in and get the retards that modified you cat to switch it back to how it was. STAT!
Man that's what happens when clueles people work on cars - they jump to conclusions and screw sh!t up.
As for the header/stock y-pipe question. I may hav been mistaken before when I FIRST ever saw the Weapon R headers, BUT DON"T BE CONFUSED NOW - ALL HEADERS EITHER MSDS OR WEAPON R, AND STOCK Y-PIPES, BAT Y-PIES ETC, WR, MSDS, TRUEBENZ, ETC., ARE ALLLLLLLL INTERCHANGEABLE OK!?!?!
