So today I installed my LBZ mouthpiece I got from Danville Performance and wanted to share a little info I found. The 4" fernco I read everyone using, was way to big to fit, and in all honesty, I am beyond stumped anyone made it work..

Instead of fighting with the fernco, I got this intake coupler from the local parts store and wanted to share. It is made by sprectre and is a 4" ID coupler with two polished clamps that literally fit like a glove, plus it looks factory. The part number for Advance Auto is 9771 and the exact title it is under on the website is Spectre Coupler/Reducer 4" to 4" or 3-7/8"--Part No. 9771

I hope this is helpful info for anyone looking to do this mod in the future.





What the packaging looks like.


This was a little reducer I pulled out of one end.



And the number that was on my receipt.
