Replacing exhaust (cat back)

For sure

Back in the day, when we were drag racing, header / collector size was a tool for optimizing torque/HP , and where in the RPM range you wanted it to happen.

The higher the engine size and RPM range, the larger the pipes.

I would think that the impact on low rpm engines (like our Tacomas) is not significant.

In addition, I like the Bosal exhaust system so far (do not need anything stainless or exotic to lighten up my wallet).

 

Update:

Really like the BOSAL exhaust system

Great value for the $
