I have installed a new manifold that was made exclusively for 82 and 84 Crossfire Corvettes. It was designed and is being produced by DCS (Dynamic Crossfire Solutions) and it is called the Renegade.
More than a year ago, I let DCS use my then bone stock 82 as a beta tester for the prototype of this manifold; we seen 33+ RWHP increase just by bolting this manifold up! Anyway, the manifold is finally in production and I received a pre production Renegade and got it installed last week.
SOTP tells me the same as the prototype did - WHOA! This manifold truly wakes up the CFI and allows it to breath!
There has been a TON of talk about the Renegade on the forums over the last year and finally this beast is about ready to ship out. This IS the biggest thing ever for the CFI and it is plug and play - just remove the old and install the new!
If you have a CFI, you can check out their website:
