Any performance improvements to be had with an exhaust mod?

02 Prerunner 5VZFE

I’m looking at Magnaflow, Gibson, Takeda, and BRExhaust

If I take the cat off will it result in any MPG improvement?

Where can I buy a blacked out exhaust tip if I decide to keep it stock?

 

Couple problems with removing the catalytic converter.
It won't pass emissions inspections.
It will probably throw a code because there is an upstream and a downstream oxygen sensor.
Modern catalytic converter are very high flow, so unless yours is plugged it really won't make a difference.
The exhaust on our trucks is very straightforward, so unless you want it noisier I doubt you will get much gain.
Amazon for a black exhaust tip.
That's my 2 cents for what it's worth.

 

For the love of God do NOT remove your Catalytic converter. But if you do. Please please please sell it to me. I need one for my 91 Toyota Truck, yours will do the trick just fine.

 

Dont hack out your cat, and don't go loud, for the sake of humanity.

Blacked out exhaust tip? Like a bolt on accessory? Tried Autozone?

If you actually want performance, you can look to headers, tuning, supercharger.

If you change the diameter of you pipes and remove parts of the system, you will affect exhaust back pressure, which can affect performance...for bad or good. It gets complicated.

 

This is the passenger side exhaust looking forward. Top left is exhaust from manifold. Right lower is pass side cat, under cab.

 

Removing the catalytic converter would make you an irresponsible Taco owner.
