magnaflow universal size?

[///M42 sport]

I want something a little louder than stock.

should I go with the 5X8 oval or the 5X11 oval?

Also is it a hassle to have the tailpipes come out straight? None of the dual in/outs have a offset.

Not going to lie but the the dynomax is half the price and sounds pretty damn good. I thought I was cheaping out but I love the sound on my 318is. If this is for your Mtech Id go with the magnaflow.

I just had a exhaust fabbed up. I put in a 3.0 m50 in my 87 e30 and went with a x pipe, 2 4" round resonators up front [where the cat was] then ran dual 2" pipes to a dual in dual out 8x11 magnaflow muffler. sounds great not too loud at all. One thing I will have to change is the spacing of the rear tips, the outlets are spaced too far apart on the 8x11 miffler, so I would suggest the 5x8 as the outlets are 4" apart instead of 5.75"
