Doing something "right" doesn't necessitate having to spend more money.

I used 1" bolts. Now I really feel like a dumbass.

 

that's a shame.

 

It depends on the flange thickness. The thickness of the stock exhaust manifolds
happens to be about the same as my SLP shorty flange. If you measure the stock
bolts (the ones w/o the spacers) they are just over 1" long. That tells me that
you want to replace with a bolt of the same length. For my application the 3/4"
bolts would have been way too short. I actually would have preferred about
another .15" on the bolts, but your only option that's close is 1".

 

I was just kidding. I wouldn't have felt comfortable going with a 3/4" bolt, but I could have saved 30 bucks. The extra I paid for a little more peace of mind would have covered one night of moderate to heavy drinking.
