Most duals are going to come with a wider diameter pipe there, so you would have to just take the flap itself out of the assembly. I suppose it would be harder starting when very cold. That was the intended purpose: easier starting when cold.

Re: Heat Riser Valve (andyg)
nothing will happen except little slower to warm and a driveability little worse until warmed up, easy to live with, just like no choke, just have to get used to it. :D :cheers:

Re: Heat Riser Valve (gmcclurg)
Another forum member who switched to headers gave me his metal donut spacer, and both gaskets since he no longer needed them. The metal spacer replaces the heat riser valve. I think he got it from Corvette Central originally. It allowed me to fix my exhaust leak. The gaskets will blow out over time when the heat riser valve tends to stick and the EGR path in the intake is all plugged with carbon. That's why a lot of stock vettes have an exhaust leak.
Thanks again John!!!! :cheers:
