Been looking at some different systems and came across this:

Formerly a K&N system I was wonering if anyone has given it a try.

Pricings not bad about, 275 aluminuized or 375, 304 stainless.

 

Try a search.

Some guy here posted about a JBA that had K&N stamped on it. It was supposed to be SS and was actually aluimized I think.

Can't recal his name but search on 'stainless exhaust' or similar.

Did a search on that link and they don't have a kit for a 4Runner. Too bad it looks cool. I had a Gibson 2.5" cat back kit on my Tacoma that I got a lot of compliments on. It did sound great. Not like a rice rocket just deep and cool. I think it was only 254 for the aluminized.

 

I had a custom system made form the cat back for my 03 non VVTi V8.

Used a stock Magnaflow muffler and a small resonated tip that came out behind the mudflap and not straight out.

Sounded unreal... folks would see the vehicle and do a classical double take as it sounded like a Cup car under acceleration

Here is the thread.

 

Hopefully the link will work

Still happy w/ it? Just ordered the stainless myself.

 

Overall, I am very happy with the exhaust. The quality is very good, I would recommend purchasing a new gasket for the flange between the cat and the new exhaust as well as two new bolts, nuts, washers. The exhaust is not obnoxiously loud, but is significantly louder than stock. At times I do miss the quiet stock exhaust, I am considering some additional sound insulating material.
