Rusted downpipe bolts

i actually wanted to clamp the Gpack on like you did scott , but i bought the 2.25 band clamps and they wouldn't work with the 2.5 Gpack , so he just welded her up solid.
 


and if you have the factory pipes still you can't clamp it, it will never fit or seal right.

my cat back was replaced before i got it so all slip joints already.
 
yep ... the 2.5 Gpack was way to big. he welded an adapter piece inside before he welded it to the stock pipe.
 


Ah gotcha, I'm gonna go pick up a 31x2.25 tomorrow. Between the leak at the cat back flange and the straight pipe, the car sounds like ass lol
 
what i would do if i was you is get under the car and measure your res now, flange to the end of the outlet tube. buy a gp clost to that size

iirc you gp guys are like a 27 inch res. mine was a 31 ( regals)
 
you can use butt clamps and some copper RTV and get a good seal if you don't or can't weld it.

every joint on my cars cat back has a band clamp now. as one by one every joint blew apart once i was putting 10 psi through it. even the muffler has one. cause it also blew off. i was like wtf????? for a few weeks lol
 
still got leaks ? those U clamps shouldn't even be sold , they're worthless. all they do is crush the pipe out of shape.
 
it never leaked. the pipes blew apart lol

installed band clamps and they never blew apart again. my down pipe is welded now, so theres 2, 3 inch band clamps on the shelf worthless to me now.
 
sell em to boner...lol
i still have those sh*tty uclamps on my mufflers and 2 band clamps riding in the trunk waiting to replace them ...in fact i got a box of various things in the trunk that ain't made it on the car yet ...lol...i'll get motivated when it ain't so F'ing hot
 


Got the old downpipe out. Can't find the right gasket, the circle rubber one, i got the one that goes onto the resonator.

Theres just that little part of the bolt left on where it bolts into resonator, any easy way to get it out? I have a cordless drill, some drill bits, some easy outs. I got tired with it and quit for the day. Should I heat it up with my little 1lb torch, try to drill it out, or hammer it out with a center punch? Cars on jack stands, and do not have too much room.
 
the 3 inch one with the ring around goes to the manifold ...the ring faces the manifold ...any parts store will have 2.5 inch dp to resonator gasket. a good whack with a hammer and punch should knock it out.

Yeah I need the ring that goes to the manifold. I hate drilling bolts out.
