Hey i am selling my old exhaust $350
Pros
This exhaust system is among the nicest available for the MR2 Turbo. It also reduces a lot of weight, since the factory muffler spans the width of the car compared to just one side. The stainless canister is clean and the tone is smooth and deep. Fitment is exemplary, and finish is top notch. And it breathes: We gained 16 hp and 13.7 lb-ft of torque at the peak and up to 28 hp in the mid to high rpm range. The turbo spooled more freely resulting in improved output and smoother power delivery.
Cons
To say the least, Toyota engineers didn't want this exhaust to come off easily. We spent the majority of the time trying to remove the B-pipe with the catalytic converter and hardly any time installing the aftermarket exhaust. Also, the RS*R exhaust doesn't have a catalytic converter (there are two on the MR2), so it may not pass smog. Keep your old pipes for registration time.
Notes
The exhaust flows so freely that we noticed the boost was peaking a little higher than with the stock exhaust. The reduced backpressure really helped the turbo ramp up quicker, and this resulted in greater output. Don't forget, this exhaust system includes a silencer which restricts some of the flow, but keeps the decibels down. You'll probably want to leave the silencer installed when you're in areas populated by your city's finest. It's a pretty loud exhaust. Lastly, remember to WD-40 the hangers and bolts to make the disassembly process easier.
