Sonava ***** I can't find the post I made about the exhaust gasket. I thought I snapped pics and sent it somewhere but I don't have them. And yeah I got a 32inch glasspack. I'll see how it all fits up first. I need to get the correct gasket maybe. And hangars. And I think I'll be ready to start

the hangers by the flanges are the round ones at the parts store, like a inch round, they do stretch.

the gasket the parts store had for like 8 bucks. or ask the muffler shop for it with the flange. that flange should cost no more then 10 bucks.

but you'll never find it at a parts store. only the muffler shop, or on line. on lines not much cheaper.

I have the hangars off the dp. That's the only ones by the rez. And I'm just pissed I asked for a specific gasket from gm and after reiterating it four times they sold me the wrong one inthink. I'll take pics and post when I get home. It's in my tool box. Red told me to get the oem gasket. Not a walker one from advanced

the cat back one, in the pic a page back is thick pressed metal. i re used it 3 times. then it fell apart when i did the header install. but i took the gasket from the car i got the headers off of.

It's still in the package I wonder if they would exchange it

I thought an actual pic of the gasket lol oops but the walker one is metal and I figured a little Rtv on both sides it'll be golden

i used it dry 3 times. it will stick to one side for ever, till it falls apart when you drop the cat back for the 4 th time lol

Is that a walker on from advanced?

Plan on going with two of these in the Oem locations

It seems like those are the only applications that will work lol I essentially have an Oem exhaust but it's from a 2012 impala and I gotta welded back together lol. What would you suggest

all the factory style hanges are at the parts store. just the rubber parts.


thi spic is th erear muffler hangers, and the bracket thatmouts to the bumper . the 2 or three along the pipe are the same. but the 2 round ones by the cat and res.

Those are the only two I need since I already have one stock muffler hanging. Just need ones like that. I need the brackets. I'm essentially doing a stock set up. Just in the process converting from single to dual

ok, you need that bracket. junk yard part. its 2 bolts on the inside of the bumper. take the bolts too.

the Y pipe hanger on the driver side, you may not need anything to hold it up. or you can have a shop weld in a hanger bar to the car bottom near the hook on the pipe. then put the hanger on it.
