View Full Version : Evo X bolt-on HFC...STILL $349!!! Gain 15+whp



04-29-2010, 05:36 PM
NEW AND IMPROVED! The Evo X 100 Cell Cat Bolt On back and better than ever. It's 304SS, mandrel bent and is a full 3". Our bolt-on mimics the factory piece. PLEASE NOTE: You may still need a mechanical CEL fix even with the bung after the cat.

What makes the MIL.SPEC 100 cell different?
• NEW! Includes 2nd bung for wideband!
• Piping and cat are 304SS
• Full 3" all the way through
• No one can beat the 100 cell flow
• 3/8" 304SS flanges
• 100% American Made

PRICE:$349 SHIPPED!

Also, now we have a dyno graph of a FULLY TUNED OEM cat vs. a FULLY TUNED MIL.SPEC 100 cell cat. Please keep in mind that the OEM unit appears to also be a metallic cat (wound metal material), and these gains are even more dramatic. And, we simply paid the shop to do a back-to-back for this customer. We had zero influence on the dyno tuning. I simply gave the shop owner my cc number and then he sent me the results. That's as close to a third party as I can get being a vendor :D

Great work Milspec and TT

I have this piece and I love it. Don't forget that it flows great WITHOUT the nasty Testpipe smells. You can actually drive the car with power and minus a cab full of toxic air

Bump for MilSpec

THis is on an MR also, so they have torque limitations to deal with the that tranny.


Matt. Oh crap. I FAIL. Duly noted.

I don't know what the AMS long DP is.

This piece replaces the OEM cat pipe and follows the dimensions exactly with the OEM-style bend.

I heard good things about this HFC. Do you know which catback and stock downpipe this goes with?
