Does it make a difference (performance and sound wise)? I'm planning on gettin a stainless steel manifold (421)... I have a mk2 vtr with a Peco duplex exhaust system.

???

mine made mine louder seems to pull better to higher up the rev range

Yeah mine seems to pull better aswell. No sound change for me tho. Probs because I still have the standard backbox on.

What make manifold you looking at getting??

not sure which one yet..anyone suggest?

4-2-1 gives better torque as long as the lengths are kept correct, 4-1 gives better power ie top end providing lengths are kept.

gmc meli thats the one 1 have its a 4-1 as thats all they do

Mine is supersprint 4-2-1 but they dont make them for y reg or later saxo vtr's. So if your saxo is y reg or later I would recommend GMC 4-1
