I assume the flange I need is for a 3100 Grand am from around the 1994 era just wanted to confirm this before ordering the part

all the way up to a 05 3400 would be the same flange IIRC...

anyway that its possible to check this? unsure if the flange is available as a part i may have to buy the entire downpipe

[3X00-Modified]

Its not separate its one part.

I just realized i saved the down pipe from the 3400 venture van any possible way of using this one?

[3X00-Modified]

cut the flange off and have a muffler shop weld a down pipe that fits to it.

[themixer]

any worry about using a flex pipe?

[3X00-Modified]

longevity... they don't last long.

this is fantastic news, found some exhaust wrap also so will get that put on at the same time to protect my shifter cables

depending the flex pipe used, it can last many years to many days. The thin corrugated tube often found at the local parts store is not going to last. That's meant for a temp "get me home without much attention/no tickets" fix. The use of a nice welded on inconel flex bellow on to non rusty (prefer new) pre existing exhaust will last a long time.

well the van parts were not usable on the car, the exhaust shop fabricated the entire pipe and flange. Its attached to the car using a similar method to the original exhaust springs and donut gasket. They even wrapped the shifter cables wrapped in high heat foil, and the down pipe itself is wrapped all the way with header wrap.

$280 later the car is quiet now I can troubleshoot all the other problems !
