If you're looking for the largest exhaust system without sacrificing the weight... look no further, ETS has one of largest diameter titanium exhaust system on the market for the MK4 93-97 Toyota Supra with a tubing diameter of 4.0" (101mm). This exhaust system weighs in under 17lbs and features a full titanium design including titanium brackets. This is the most free flowing exhaust with minimal bends on the market.
Unlike some of the other "titanium" exhausts on the market that claim to be full titanium and only use a titanium muffler. The ETS Supra Titanium exhaust is constructed completely of titanium tubing, full titanium muffler and titanium brackets.
