1st setup
------------
1) Limit AXS 4-2-1 exhaust Manifold
2) 2.5 Inch piping
3) Apexi Megaphone Dunk Muffler with Limit AXS centre bullet
Result:
Engine feels very slow at low revs especially 1st 2nd and 3rd gear. Response or performance can be felt at 5k rpm above. tremendous top end power. climbs from 130km/h to 190km/h (and more) without hassle, a VTEC and Alfa (New model), Really sorry guys.....failed to tail me at high revs/gear but i was beaten easily at low revs/ gears...... but fuel consumption is higher and engien felt like struggling to accelerate... RM 10 per 65 km journey
Quiet at 5k rpm below
2nd setup
------------
1) Fujitsubo Giken 4-2-1 exhaust Manifold
2) 2.0 Inch piping from manifold to fuel tank.
3) 2.5 Inch piping from fuel tank to muffler
4) No centre bullet
5) Apexi Megaphone Dunk Muffler
Result:
Engine climbs to 120km/h very fast, smooth response, 1st ,2nd to 4th are very enjoyable. But lost top end power, engine really have to put an effort to chase up to 180 km/h. But once the accelerator pedal is raised, the rev is "KEPT"..... rev doesn't drop quickly, it feel like the pedal is still stepped on. Fuel consumption is very good, not noticed but i think it is RM 10 for 97 km journey now.
2.5 for rear piping is to see whether it will help at 5th gear, it aids a bit.
Slightly increased level of sound, Quiet at a any revs but when the pedal is stepped on hard, there is a rattling sound produced.... WICKED......
Next setup (friend's car)
------------------------------
1) 2.0 piping
2) Apexi 4-1 Spiral Exhaust Manifold without centre bullet
3) Tanabe Muffler
- Waiting for results-
Take note that 4-1 Exhaust Manifold is for top end gains. Want to see whether the top end and acceleration can be balanced by this setup.
I think 2.3 inch piping is suitable for 4age users whom have done modifications to the internal of their engine. I have read in Jap mags that they are using 2.5 inch for max modded 4age (NA). Please correct me if I am wrong. Becos there is lack of info regarding what exhaust setup is suitable for 4AGE, i hope we could all give opinion from this thread.
Note: I am sorry if there is any wrong facts and i hope this will be a useful info for all of us.
