I've been waiting to get a few of the remaining  "issues" I've had with my 
Magnaflow cat-back install before I wrote a little something about it on 
here. But this seems like a good time so I can answer some of these 
questions.

   The system comes in 3 pieces. The mid pipe bolts together with the front 
resonator and the rear muffler sections with some nice looking flanges. That 
part is easy. The stock muffler on my 95 was bolted on just after the cat. 
Well, "was" bolted on. I did get one of the bolts unscrewed. The other on 
just crumbled to a pile of rust when I put the wrench on it. The only other 
thing you will have to do is cut the stock exhaust so you can remove it out 
from behind the rear suspension. (I already had the suitcase chopped so this 
was easy.) The front resonator section is supposed to clamp onto the cat. I 
clamped it the best I could and it still leaked. So now it's welded shut and 
all is good with that. The rest of the system lined right up and had pretty 
good fit. Or so I thought. There was an extra hanger on the mid section pipe 
that was too close to the bottom of the car. The first drive it was super 
loud because the clamped joint was leaking but I could already hear that 
extra hanger bumping. After I had the muf-shop weld the joint and cut the 
extra hanger off ($10), I still had and still have a problem. About a day 
after, the whole system like shifted and something started to bang around 
again. A quick look showed it to be the mid pipe banging against one of the 
metal parts on the suspension. I took it back to the muf-shop and he bent 
the hangers trying to get it away from the metal but he couldn't get it far 
enough away. It still rubs. He did give me this piece of heat resistant 
rubber to mount someway between the 2 peices. I'm going to do that Sunday. 
Hopefully that will be it.

Now for the fun part. The sound is so sweet. Very mellow and not much louder 
than my stock exhaust with the suitcase chopped. My open air filter is still 
louder than the exhaust after about 4000 - 4200 rpms. It seems to have more 
power all the way across the revs. (Butt-dyno only) And I'm not basing that 
on the sound cause it's not really any louder than it was before. It also 
has a really sweet sounding spot around 2700 rpms sorta like it did before 
with the suitcase chopped at about 3100 rpms.

All in all, I really like it. I just hope I can get it to stop banging 
around. I do really like the daul pipes out the back. In fact, while at the 
muffler shop the 2nd time, this guy that had an Alero with a HUGE tail fin, 
chrome 18's, and supposedly a 150 shot of NOS was there and he saw the rear 
tips and was like "dude, you should get like a 7" tip on that" and the guy 
that worked there was like "no man, you need to see this, this is the real 
thing"  I just smiled.
