4-1 manifold?

[shawsyVTS]

ok for my mk1 saxo vts, iv just bought a stainless decat pipe, and straight through stainless race tube with backbox.

im thinking about complimenting it off with a stainless 4-1branch manifold, although they are relatively easy to fit,
is ther any other work involved other than fitting? i.e will i need re-map or are they simply bolt then drive? thanks

i kno itl be a great performance upgrade offering between 10-20% power increase, i just want to make sure car wont b off road for long

Forget about the 10%-20% increase that wont be happening.

[shawsyVTS]

ok but is there more work involved other than bolting on and changing gaskets?

[nath106]

its litrally 12bolts

take it off, fit new gaskets and refit the manifold

do up 12bolts

done.


youll notice an improvement for sure but not 10-20%
