Can anyone tell me what size the stock pipes in and out of the stock muffler are? I'm lookin to swap in an aftermarket muffler to get some sound out of the TB. I just wanna make sure I get the right size. I've looked here and on TV but I couldn't really find a definitive answer. Found what the SS measurements are but wasn't sure if they are the same. Your help is greatly appreciated.

you know with that gibson everything sounded good till that last shot...it sounded a bit ricer to me...like if no one looks they wouldn't think it was a truck you know. The magna flow its much better at giving a v8 sound to me :yes:

Anybody got any suggestions on a muffler? I can get a 4x9x14 Magnaflow on the Bay for $71 shipped. That's the leader in the clubhouse right now. I was also thinking Flowmaster Super 50 but haven't seen or heard anyone with one of them yet. I want it to be decently loud outside but not loud on the inside.

So I've watched a bunch of videos on YouTube of V8 TrailBlazers with exhaust/mufflers. Most were SSs but I can't imagine mine would sound much different. I'm gonna go with the Magnaflow 11229. I've already cut the resonator off. Anyone wanna talk me out of it?:biggrin:

Ok so after reading some more on the OS and TBSSowners, I'm back to undecided. Some people say the 11229 is really loud and some say it isn't that loud. It's hard to tell from YouTube videos. Would the 12229 be a better option? Anyone have it on a V8? I wish I was 21 instead of 31 and didn't care how loud it was. :frown:

What I would do is se if Magnaflow has a CatBack system for your ride, get the dimentions of that muffler used in the kit, then try and find the muffler.

Magnaflow cat back for the V8s comes with a resonator and people say it sounds just like the stock exhaust. Don't know if that would really work out.

just remember when you search on you tube for vids the 5.3 came in alot of trucks.plus if you dont like the sound you can always add a cherry bomb in afterwards to quiet it down some.i just cut off the resonator and am happy for now.it passed the wife test.
