'12 2 LS

I started with the Flowmaster axel back, American Thunder, about $550.

Liked it allot, just enough volume to constantly remind you that it is not the same ole lame system they put in it. Yes, some drone, not enough to really annoy me. Rasp, well it is rare I ever really stomp on it so yeah there was some rasp.

So I installed the Mag. res. x-pipe in place of the stock H pipe, and the rasp was gone and no drone. But now it was just too tame sounding and I was, after a few thousand miles wishing I had not added it. (This is in conjunction to the set of Flowmasters).

I was also hearing a whole lotta bang and clang after adding the M.R.X, I had tried a few times to either cusion or sandwich it better, both times fail. But it could be fixed, if I took it to a competant muffler shop, problem is, around here there are no real performance oriented muffler or custom exhaust places. Sure, sure, I could find one if I look around enough, this banging sound could be fixed, it's just that I"m not happy with it's sound.

So right now I have taken it all off up to the cats, I ordered butt joint clamps, got them and am all ready to re-install the factory H pipe, and keep the Flowmasters.

That said, it wasn't till recently that I found out that the Mag.Rex.X can be used as the sole muffler, and go straight pipes right after that. This would mean I'd have to purchase them, and at this point I don't think I want to gamble on it. I mean, than I'd be holding the Flowmasters, and the factory pipes from the H pipe all the way back.

So, though I think going Mag than straight pipes would sound good, I think I'll just put back the Flowmasters with the H-pipe. At least this way I"m sure I know I like it and it costs me no more, in fact I can sell the M.R.X really easy since it is so popular.

BTW, to add on the M.R.X to a V6, you have to cut the weld joints which connecting the factory pipes which are at two separate spots, because the center to center is about 1/2" wider than the factory H-pipe. To do this you will need to drop the whole thing, flip it and cut. Sure they didn't weld it together for no reason, I dunno? Maybe to prevent it from rattling?

Now, there is also the girth of the M.R.X, it is much larger than the factory H-pipe, the steel bracket which is located immediately after it, just barely cleared it.

I bought my clamps at Summit, at first thought I needed lap joint clamps but than realised my mistake and got the butt joint sets. (for re-installing the H-pipe)

I know it sounds like I'm downgrading, but have you seen the vids of the Z28 exhaust? Yep, same H-pipe as I have, and if it's good enough for that V8 firebreather, it's good enough for my V6.
