Stillen Gen3 Intake, Berk Hi-flow cat, and Stillen cat-back exhaust

What tool do u use to cut the space for the intake to fit

Denny McLain

High speed pneumatic grinder using a porting carbide tip. Took maybe 4-5 minutes at most to do both sides including clean-up. You need a compressor, but the tools themselves are quite reasonable.

Used to do my own intake porting and some mild head cleanup so I already had porting tools. In fact, I was tempted to do some cleanup work on the header inlets as they are pretty good, not perfect.

You could stand to be a little less abrasive about the situation. I'm not sure what's going on with your situation, but even the first batch of Stillen CBE's (which I have), which lots of people had issues with clearing the crossmember, didn't seem as bad as you're describing this, and it's been quite a while since forum members here started reporting a higher success rate due to the design changes. Lots of them have gone in fine in the past couple of months, haven't really seen any fitment issues reported lately until yours.

Maybe try loosening the slip-joints a lot and freeing them up with a mallet to make sure they slip well when you jack it back up into place to retorque again, that would be my next guess. In order to raise the center further than the last place you torqued it too, the slipjoints would have to go "shorter", which if they made any impression on the underlying pipe means they need to slip over the bump of that impression to adjust now.

Would describe it best as "irritated" as the headers really kicked my butt and the 02 from Nissan still has not arrived. Need to do more with my life than lay under a car in 100 degree heat and as mentioned.....my play time ran out.

Still feel that it should be a "non-issue" and even though others are claiming success, others are not (like me).

Wondering how many other brands of exhaust you have to jump through this many hoops with? One of the reasons I favored the JIC is not having slip joints as for some reason, really never trusted them. We'll play with it and make it work, certainly didn't expect to have to.
