Actually yes. When I went for dyno last time I heard a story of a father and son pair going dyno. Dad had stock exhaust, son had huge pipes. After dyno, they actually found that the dad had a higher power output.Wah sampai worse than stock ah? [emoji3]
Piping size or extractor? What car was this? :hmmmm:Actually yes. When I went for dyno last time I heard a story of a father and son pair going dyno. Dad had stock exhaust, son had huge pipes. After dyno, they actually found that the dad had a higher power output.
Ok la that makes sense then. I've heard a lot of stories like that about enlarging piping and muffler size but still using the stock extractor. Super pointless mod. :shot:Both wiras. The son had oversized piping and muffler. Not sure about extractor though.

Got a lot like that one. Do A but B and C not done, or do B, A and C not done and so on......lolOk la that makes sense then. I've heard a lot of stories like that about enlarging piping and muffler size but still using the stock extractor. Super pointless mod. :shot:
your current engine is 4g92 right? RM2.5k inclusive new radiator? U can bore it though.My Mech just told me to overhaul & will change all the piston. But not all new parts.
Roughly 2.5k
Ya lor... weird thinking. Then after that complain that the mod doesn't work the way it should.Got a lot like that one. Do A but B and C not done, or do B, A and C not done and so on......lol
I din't plan on doing anything big to the engine on long run as this will be my daily car for quite some time. Don't want to do major engine mods to maintain the FC as it is already quite bad in the first place.I think you're misunderstanding me, I didn't say pointless, I said at this point in time with your 110% stock engine, it'll suit a 4-2-1 design better than 4-1. It's up to you at the end of the day. I don't know what you plan to do with your car & engine in the long run...
Another thing you should know, an extractor swap regardless a 4-1 or 4-2-1 doesn't mean your car's powerband is going to dramatically change with either, and neither is your powerband going to dip so sharply that you'll feel a massive difference.
Btw you can get straight through mufflers that are quiet... just go get the largest longest straight flow muffler you can find and 2 large bullets/midbox I can guarantee the car will be quiet.
It's cast iron. Surface rust I assume?
Like trying to emulate an unequal length extractor to mimic boxer engine sound.A wrongly tuned one!
Exhaust mod not gonna help with FC. If your 4g15 manual FC is bad, it needs an overhaul. My car use to be a 4g15 3spd auto. It was modded and my only option was either change to manual gearbox or swap the engine coz the FC was super terrible.I din't plan on doing anything big to the engine on long run as this will be my daily car for quite some time.

If so, I think I'll just do the whole piping from extractor to muffler at one go instead of just doing the extractor first. Perhaps more noticeable gains can be felt after that.
By the way, until now I am still unsure on what the bullet/midbox actually do. Can I choose not to use any bullet?
Did your current engine fare better in FC than your previous one?Exhaust mod not gonna help with FC. If your 4g15 manual FC is bad, it needs an overhaul. My car use to be a 4g15 3spd auto.

Resonator/midbox functions to silences the exhaust note just like a muffler does.
Of course it does. It has 300cc more power and 4 speed autobox comprared to a 3spd. But the gearbox ratio is the same. Only the final drive is different and got OD (4th gear). Worth the swap.Did your current engine fare better in FC than your previous one?
Just dont redline it daily.Of course it does. It has 300cc more power and 4 speed autobox comprared to a 3spd. But the gearbox ratio is the same. Only the final drive is different and got OD (4th gear). Worth the swap.
Can't resist the torque after tuning.Just dont redline it daily.
Thats why cannot turbo. Even more poisonous later.Can't resist the torque after tuning.
