Anyone familiar with these?

Summit Racing® Metallic-Ceramic Coated Headers SUM-G9105

Seems like a really good price for ceramic coated headers, and according to the instructions I can use this Y-pipe with them:

Doug's Headers Y-Pipe Kits D901

Would this be a good budget set-up to replace my puny LG4 exhaust? I already have a flowmaster muffler and it looks like I wouldn't need much more piping to connect it to the intermediate pipe that comes with Doug's.

PS - I don't have a cat and one isn't required here

 

Double check y pipe as I believe they are made for Doug's headers, may have to get y pipe fabbed.....

 

Straight from the instruction pdf they have their on the site it says:

"To complete the exhaust: For connection to the factory exhaust, purchase aluminized Y -Pipe, Part No. D901. For a custom dual exhaust system, purchase 2 reducers Part No. H7238."

It does say at the top of the instructions its for "1982-92 Chevrolet Camaro" but I assume the same would apply to a Firebird?

 

Yes, it should... they're the same underneath
