ask tonkka supplier see if they custom mental header for MRS engine...

seek advice from toyota dealer or surf web to know about cat conv removal as some new aged car cant be remove as it will effect the setting of the system and thus will cause damage in long run...

for 1zz engine (MR-S)
4-2-1 low to mid
4-1 mid to high (suffer a bit on low end)

most japanese aftermarket manifold is 4-2-1 design. of course the downpipe & exhaust plays a role too.

NA cars is very important & sensitive on pipe sizes. too big loose power (unless u have aftermarket cams), too short, loud but lose power in pick up.
