The pursuit of F
^^^^ Agree, since the stock exhaust is identical on the 250 and 350 any aftermarket exhaust for the IS will fit for the 250/350 including AWD/RWD. T
However, when I got mine custom built, my exhaust specialist did not want to put 2.5 inch tubing on a 2.5L V6 204 hp engine which the Magnaflow bolt-on axle-back comes with. (Stock is 1.75") Reason is after a certain increase in diameter, you lose the optimal balance of backpressure and free-flow gas which can result in a loss in idle torque. On my 250, he said 2.25" tubing would be optimal for the car's engine output. So the 2.5" axle-back from Magnaflow will physically fit on the 250 but there's a small risk you may lose a couple ft-lb torque on take-off.
FSportlex, please post feedback on the kit. Is it with the same 2.5" tubing for the 250? How does it sound? And how does the power feel?

So I installed it with no issues so it does fit and as for the torque goes and losing power it honestly feels the same I'm not going to dyno it but boy does it sound sweet .....and it most likely is 2.5 if I remember correctly .....I will post sounds and video by tomorrow
