Hi, recently just convert my 1.6 4g92p from auto to 1.5 4g91 manual using clutch cable type gearbox. Want to ask, use straight flow good or s-flow good for pickup?
I've heard s-low for auto cars more good, straight flow for manual more pickup?

And how to know the fiber 'left' in an straight flow muffler if i wanna buy from halfcut shop?

If i remain my ori piping direction, change to straight flow is it more pickup? Because im using straight flow but how ever when chg bek to normal, the car is so heavy to move even press fully...

ya i know, but the front pickup is like a cow...coz maybe back pressure too much?

Erm, my current setup are actually standard 1.6, which is 4-2-1 extractor to cat back, then a small bullet and straight flow FireHill exhaust, too loud then i change back to normal wira exhaust and the car feel 50% heavier...piping are using ori direction...i don't want to invest too much money on changing piping size and route because of the fc...further more my wira oredi makan fc like gila, full tank only go about 280-300km/h after i convert to manual, befor ethat auto only can reach 260-270km/h

HAHAHA, sorry...is 260km =.= using back ori s-flow muffler, my wira only can run 8.6/litre...using straight flow is about 9.5/litre... 8.6/litre is same as camry ron97 =.=
