95 riv exhuast

i want to upgrade my exhust on my 95 riv but dont know where to get it from, and alos what other upgrades do u think i can do to my car and where can i get the parts to do it

series one performance parts are harder to find but you can start with 180* t-stat. as far as exhaust goes, the riviera has unrestrictive exhaust for the series 2 s/c engines, the series 1 s/c should have no problems with back pressure(since the exhaust is the same). but if you insist, SLP make headers, ZZP makes a 3"DP and cat delete. have someone custom fab a Y split to replace the T right before the mufflers. Borla Turbo's are great sounding and flowing on our cars also.
