I've had a few aluminized Gibson exhausts over the years. If you plan on keeping your 4Runner for any length of time, I'd suggest a Stainless Steel muffler and tubing.
I had a Stainless system on my S-10 years ago - I was very happy with it. back in the day they would install a system for $5 if you went to their facility and purchased it there. I didnt know they made a system for the Runner.....may have to look into that. I would love to hear a sound clip if anyone gets one of these.
You know... plenty of muffler shops will put on a muffler and new piping of your choice for less than $300...
Then again you have some yoyo under your truck with a welder. I like to do my own work. Alignment, tire install only time I go to a shop.
Same here but not really a fan of the bolt on exhausts since cat theft is a problem around here. Tis why my 4Runner is garaged.
Alas, if I had a welder and any skill at it I would have had a new exhaust on my truck over 6 months ago, hence why I'm researching shops to do it again. I might just take it to the place I had my Pickup done, they did awesome. If you know the shop or can see some jobs they've done before it eliminates some of the unknowns.
