Default CNC Machined LB7 Mouthpieces in stock

We've had these for a couple years, but here's a picture of one that was freshly cut on the CNC.

It features a smooth taper from the bore out to over 3.150" .

They are good for about 10hp depending on your setup.

They're smoothed through the entire bore also.

I found a hair pin hole in mine today it looks like it is in the weld! I live in terre haute, IN also wondering if you could take a look at the data log on my efi live and see what comes up how much do you charge?

A leak pre turbo is not a "boost leak". It is just under vacuum it will not effect boost numbers FYI

Maybe I'm not understanding what is done here, but I thought this was a stock mouthpiece that has been opened up with a CNC machine. I didn't think there were any welds on it.

I didn't think it was a boost that's why I haven't fixed it. Prolly helps if anything lol and my mouthpiece is welded all the way around where it bolts to the Turbo.
