I'm looking at getting a full blown twin scroll sidewinder manifold and have 2 questions:
1- Do I need to use a filter relocation kit?
2- Do I need to remove my crossmember?

I tried calling them direct but no ones been answering their phone.
thanks

 

1. Not required but recommended
2. Not required

 

You'll need to relocate your oil filter if you plan on running their downpipe. No need to remove the crossmember with their manifold.

 

1. understatement of the year. the saying TAF "tight as f@#k" doesnt begin to describe it. must be relocated.

My open FBM manifold had millimeters of clearance between the downpipe and the Canton block. My divided (Jake's old manifold) had ~1-2"; I assumed this was due to the fact that Jake's was likely a one-off/proof of concept.

With the 5.7 litre, I only have 4.5" of clearance from the exhaust ports to the frame rail

 

5.7 litre, no big deal

 

Question #3 -Can I still run my fuse box under the hood and a slim battery?

 

I would relocate the battery and move the fuse box away from the manifold like this or similar. I plan to put heat foil around my fuse box to help also.

 

 

U can leave the fuse box under the hood just have to relocate where it is. The factory heat shield wont work with the fbm mani so u'll need a custom one
