My 2cents for a great sounding 3vze combo-
the 3.0L v6 4runner sounds great with the Thorley Header, Jardine Exhaust and Magnaflow Carsound High-flow Universal Cat.
if you are in Washington State, I HIGHLY recommend Randy's Custom Exhaust in Marysville. This guy makes his own headers!! He is friendly and his rates are awesome. I drove up there with headers and no muffler on...my old cat barely hanging on...and he was able to design and fit a lovely routing from the Thorleys through the magnaflow and down out the jardine muffler and exhaust.
He even fixed up a few loose ends on the header install. Now everything sounds great and he only charged me $98 for 2 1/2 hours of labor. If you're in WA or BC Canada it's totally worth the drive to Marysville. Also, the Tulalip factory outlet mall is there too so the wife/girlfriend can shop while you get your power!
Anyway, sounds great, not too loud when driving nicely but deep and juicy when you gun it. I can go up hills in 4th and dart in on the highway now, feels like a much more powerful vehicle.
I'm glad I did this and it was worth it. thanks to all of you for help and advice!

 

I just got my muffler on it for now (going to be doing an exhaust rebuild later this summer with new headers, pipes, and a muffler) because my tail kept falling off, but it actually is a little quieter, and sounds a lot better.

 

i like the single chamber flowmaster

 

I wanna hear that. Did you run 2.5" piping or bump it back down?

 

i'm running flowmaster 40 series also, stock cat but duals from muffler back..sounds really nice

 

What kinda sound do you want exactly?

For - normal acceleration? Rapid acceleration? Highway or around town cruising? Idling?
