I am looking at upgrading exhaust but I really don't want any noise at all. I had a Dynomax Super Turbo on my S10 and I liked it. I'm also hearing about the Borla Xs. I have the 2.8 and I plan on running the exhaust in the stock location or possibly further back. What does everyone think? Are there any sound clips of the 2.5 on either muffler? I haven't had any luck. What size is our exhaust by the way? Thanks
