Default Different exhaust question - Modify Magnaflow cat-back?

I'm not really liking the magnaflow cannon tips on my car. I saw a 3.5" mufflex system locally for sale, but it has the spintech muffler everyone says flows like crap.

Now I'm debating just ordering a magnaflow 3" bullet muffler and the necessary 3" stainless bends, and making the magnaflow setup a 3" single on the left. This way I'd end up with a stainless exhaust, the tip could be tucked carefully away.

Anyone do this? It should be the same (possibly better) flow as the cat-back magnaflow, but without the huge tips.

Why not just cut the cannons off and clamp on some cheap turn downs? They're only like $12ea at most parts stores...

Because then they'd still be hanging down? Also, there are support brackets welded to the cannon tips.

I am actually running the spintech TOTL/2OTL, not sure about flow. I think it sounds pretty damn good though. I am using GMMG/Mad Hammer slash-cut tips FWIW, had them laying in the garage. The slash cut tips that come with the system are a little larger, not by much, I just happen to like the GMMG/Mad Hammer tips better.

Unless your piping is welded to the muffler, you can loosen the clamps and point the tips up slightly (once you cut the tips off) - see pic 2

The two rear hangers are there to support the weight of the tips. Once theyre cut off, just unbolt the frame brackets and sell 'em with the tips (I got $60 for mine). The front passenger side hanger is welded to the over-the-axle pipe and the driver side front hanger has about 2" of pipe after it before the tips - if you cut at the right spot, you keep that hanger and have plenty of room to clamp turn-downs - see pic 1
