I'd like to use the Downpipe studs which are almost half the cost of the Turbo studs ($10.24).

However, the DP studs are about 3mm longer.
I don't see any clearance issues, do you ?

I'd like to use the DP flange nut because it has a longer useable shoulder then the turbo flange nuts. Any reason NOT to use these nuts ?

I believe they are ALL made of non-magnetic Inconel.

Thanks,
