i am driving myvi 1.3 manual
i had change already extractor to 4-1...
rear exhaust still stock...
this is my need and question below...
1. track day use
2. stright flow or use s flow better
3. if from extractor until end kosong izzit will be better pick up?
pls help i am just newbie with exhaust

 

[N/A secret]

Straight flow better for ur myvi, until the end kosong will result in later power in higher RPM.

My oppinion: use straight flow, from extractor until end dont put bullet but piping diameter dont oversize too much :)
