Exhaust pipe type

[RichLV]

Hi guys.

I'm gonna begin building a 3 inch turboback exhaust in the coming week and we're unsure what type of stainless steel to use. Guys who have done it themselves, what alloy type would be best for the downpipe and pipes in general? I've heard that SS tends to stretch with temperature.

For the record, I'm going with VEMS and a K24-7200, to give an idea of power figures.

Cheers!

Anyone?

Im no expert but id guess 304?

I've always used 304 and haven't suffered any fractures. If you are using v bands, make sure the clamp and bands are all stainless too.

304 in all length or only the downpipe?

Use the same throughout. I'm told 2.75" over rear driveshaft on coupe is better. Mine is extremely tight with 3"

Great, thanks! Mine is a UrS4, so space is not an issue.

304 is fine but 316 won't discolor as much if your fussy.

Got hold of 316 for free. Will go with it.

Thank you all!

Would like to switch to a V-band connection. And maybe there's something for the WG flex pipe too?

I need the same sort of vband adaptor for mine too.

Just need to get thr manifold finished then i can start with the exhaust
