OK, Every one chime in on this one, who has done it and what did you do.

I replaced the exhaust on my 93 4runner with a 2.25" magnaflow cat back. It sounded great for a 3.0 v6 nice low tone outside and not a noticeable differance from stock muffler inside the cab.

I had my muffler shop price out a 2.5" magnaflow setup for my 2003 Sequoia with 60k on her. he wanted $279. that included muffler, 2.5" pipe, flanges and gaskets, and he would remove the stock exhaust in a way that I can put it back on if I needed to.

All comments and remarks are welcome

if you ask why? my gas milage on the 4runner went from the stickers 14-17 to 18-24 miles per gallon and had a few more ponies, I also was using a K&N Filter to let in more air. if you want to hear what a 4runner v6 with a different exhaust sounds like check out this link
