Yesterday I went to a local exhaust shop and was asking them about installation of my headers and high flow cat, and I asked the mechanic if the piping was crush bent. He said not, that it was hydraulicly bent. I have no idea what that is. He estimated me $250 for installation and the 2.25inch piping.
I called a performance exhaust shop, and asked him about his piping. He said that he crush bends, but can get mandrel bent piping for about $200, and he charges $75 to install parts that I supply.
My main question is what the hell is hydraulic bent piping?
All I know is that mandrel bend is the best, although a lot of people/places will tell you its not necesarry for our cars but I did it and I am happy with my decision although i cannot compare it to crush bend. I say just do the best there is especially for that price.........mine cost me $500(can) which included a resinator and they welded on my muffler and cat. that I already owned
I have one true love in my life...And my girlfriend sits next to me in it
I have no idea LOL
Just go with the mendrel bends...

I've asked a few people, and none of them knew. I think he was just feeding me some bull@!#$ because he knew I wouldn't get crush bent. I will go with the mandrel bent piping though
I hear good things about it.
mendrel bends for a cavalier are useless unless your running some sort of power adder.

Actually not true. By having a mendrel bend, you're garanteeing to have a perfect bend. In my case that's important because I have a dual exit setup so to have 1 or 2 bends messed up on a crush bend would effect my performance/exhaust flow.

Yeah I probably will. Just have to save a little more so I don't deplete my bank account
Hydraulic bends are compression bends which are close enough to mandrel.
Compression bends hold the diameter of the pipe through the bends, but in a different form. Compression bends make more of an oval shape in the bends rather than being round.
Compression or hydraulic bends are better than crush (compression bent is what i have), and almost but not quite as good as mandrel.
Most people will save some cash and get the compression bends since the difference is minimal unless like Borsty said, you are running a power adder such as boost or nitrous.
exactly what he said, its like this
crush bend---------crappy oem style, avoid
compression bends--------good, but not as good as mandrel
mandrel----------best, go for it if you can afford it, but compression is just fine too

as i have said many a time before on this site and will continue to hold my opinion. mandrel bends, for the cost OVER compression bends, don't do much for the extra cost. they look prettier, but that's about it. and when dealing with exhaust... who really looks that closely at it. You don't lose much in the oval shape as long as the diameter stays the same.
