I previously had replaced the muffler with a Magnaflow.

The pipe from the muffler back got replaced with a 3" pipe (vs. the 2.5") and I had the resonator (spell??) removed. I also angled the tailpipe out behind the wheel so it would not get scrunched by the bumper again.

The Toyota installed pipe had an area where it was routed above the frame that was pinched that brought it down to about 1" there. The tech said that was from the factory and several of my friends said they have the same thing. They did this to make it easier to route the pipe.

Well the 3" pipe fits in that area without have to crimp it if you make the right bends before and after. It's tight, but does not bump anything.

So I removed the restrictive pinch above the frame. Replaced the 2.5" from the muffler back with 3" and lost the resonator.

Boy can I tell the difference. Not sure if you could on one that isn't supercharged. It's much quicker on the pickup.

I didn't have my camera at the muffler shop, so I don't have any pics of the pinch.

Simple, cheap mod that I would recommend. Was thinking of doing some kind of custom exhaust, but with the 3" pipe and the Magnaflow, I feel I have reached all the customization required.

Romer,

This sounds like a most excellent mod! I would love to see some pics. Can you also outline / break down the cost? I'm also planning a Supercharger in the late winter or early spring (depending on cash flow).

Thanks,

Dan
