just bought the maganflow cat backs on performance peddler for half the suggested retail. what all is needed to install the duals? what tools are needed? how ong does it take?

 

Welder, jackstands, hangers, and clamps.

 

is a welder needed

 

No, but I think it is nicer welded up.
I pd a shop $60 to install my last cat-back.
It's kinda worth it. They weld it and install it just right.

The only place they bolted it was to the cat.

 

Well I didn't weld mine, all you need is a metric socket set and you're good to go. I didn't even have to put my truck up on jack stands or anything and the clamps are doing perfectly fine.

 

I clamped my 16612. The first day, I had leaks and didn't like how it turned out.

The next day, I disassembled the system and reinstalled it, taking more care to orient the muffler they way I wanted it and the tail pipe the way I wanted it. I began bolting the clamps from the front and working my way to the back.

Along the way, I overtightened a clamp and broke a bolt (*doh!*) I used the remaining clamp and hooked up everything except the tail piece. I left that "floating" and then drove down to a local muffler shop. Once we had the tail pipe positioned the way I wanted, it, he welded it together.

So aside from that mishap, all went well, but I think welding the tail piece would be a good idea since that's quite a bit of weight for a clamp to hold without sagging.

 

yeah pretty much sockets & some wrenches & you can install your own catback. Welding is more secure & a stronger hold though. Removal for the stock exhaust can be very fun if you have a sawzall haha
