    So guys, I got a link on a very new full ss exhaust with magma flow muffler for a great price. My question is it came off an ext cab nbs Sierra with the 6.2l it's a cat back system. Would it fit my 4.8 ext cab? I can get a picture tonight. I'm finding out what series magna flow muffler is on it asap.

    Should fit because both trucks are ext. cabs and NBS. Now with that said you won't see much of a performance gain because the intake and the exhaust are the same for the 4.8,5.3 and the 6.2. If the stock exhaust flows enough for a 6.2 than it flows more than enough for a 4.8 hence the reason you won't see much if any performance gain. It will sound better.

    I believe that it's 3" all ss mandrel bent and welded. Hoping I might see a little boost in performance. I'll probably pick it up and not put it on till the spring anyways. No point in putting it on just in time to get crooked by some snowbank. If it ever does snow here in toronto.

    And that's what I figured, both ext cab both 6'6" beds should be same hangers and such. Thanks for the reply hopfully I get a few more confirmations.
