Are you saying rubbing issues from the primaries?

Yes, one of them interferes with the steering shaft.

Thanks Ricco. I went with the Kooks 1 7/8th to avoid any potential problems.

Btw I got the race pipes and high flow cats and I am supposed to be able to change them out pretty easily.

I ordered the race pipes and the midpipe to connect to them but I guess I got the midpipe that connects directly to the headers so i just need to take the race pipes back to Phastek.

We should have the parts to complete the in-tank pump tomorrow and when I get back, I will be going to the garage to load the beginning tune from Ted and then we will be able to start the tuning process...93 octane first and e85 after.

I have Kooks long tube headers...1 7/8

Did you get the Kooks mid pipe too? Wondering if you got the one that fits direct to their headers or to their offroad/cat pipes?

I don't think so. It was just LT's and the race pipes...but they fit directly to the stock midpipe...I should probably ask to be 100% sure.

I got sent to the store to pick up some parts to connect the catch can and didnt see them make that connection.

Ah ok, wasn’t sure if you were doing aftermarket mid pipe or keeping the stocker. Headers and off-road pipes will connect to the factory mid pipe for sure.

Ok. I need some help on this one Ricco. Today when I went to pick the car up, they said that the headers connect to the race pipes, but from the race pipes back, it doesn't seal correctly. I am assuming that is because I need the midpipe or something?

I need to figure out what we are supposed to do to connect from the LT's back given the additional support under the vert.
