UPDATED 2.4L Performance Modification List
Intake: The stock air box is highly restrictive. Freeing this up would provide more air for combustion and increase power output
- Cold Air Intake
- Short Ram Intake
- Intake Manifold
Exhaust: The less restrictive an exhaust setup is, the more power will free up from an engine. Our 2.4 stock exhaust system is decent (has 2.5" piping), but it is restricted by the header, cat (in the downpipe), and the exhaust section from rear wheel back (which becomes 2.25" piping and has a restrictive muffler)
- Header (Exhaust manifold)
- Long Tube (high-end gain)
- Mid-length (mid gain)
- Shorty (low-end gain)
- Turbo (for turbo applications only)
- Downpipe
- Catback
- GM Performance Parts (Performance/Touring) Videoclip
- Corsa (Sport/Touring) Videoclip
- Magnaflow (either 2.25" or 2.5") Videoclip
- Megan Racing PIC
- SLP Loudmouth II Videoclip
- SLP Loudmouth II Dual Outlet Videoclip
- JBP Vortex 3.0" >>
- Pacesetter Videoclip
- Ark Racing N2 (not produced anymore) Videoclip
- Ark Racing DT-S Videoclip
- Ark Racing GRIP INFO Videoclip
- Tusdo N1 >> Videoclip
- Borla Videoclip
- Hahn Racecraft 3" >> Videoclip
- Clear Image Automotive (either 2.5" or 3") >>
- Stainless Works >>
- CTI 3" Videoclip
- ZZP 3" >>
- Custom piping >>
Engine: (requires tuning)
- Forced Induction
- Camshaft
- JBP Tri flow camshaft >>
- Custom regrind
- Nitrous
- NOS
- Nitrous Express
- Zex
- Holly
- Vemon
- DynoTune
- Throttle Body
- Throttle Body port/swap
- Individual Throttle Body kits
- ZZ Performance Throttlebody adapter plate >>
- Injectors
- Cylinder Heads
- Pistons
- Wiseco
- Connecting Rods
- Electrical
- Jet Performance Chip MAF sensor
- Crate Engines
- JBP LE5 Performance crate engines >>
Pulley
- [*]
Transmission:
- Manual
- Short Throw Shift kits
- TWM Short Shift Kit
- B&M Short Throw Shifter
- Ark Performance
- Any STS kit for the Getrag Transmission in some 2.4L and all Ecotec equipped Cavaliers will fit the 2.4L manual transmission INFO (Some may require slight modification to fit properly)
- Clutch Kits
- Exedy Racing
- SPEC
- Competition Clutch
- Flywheels
- Fidanza
- SPEC
- ACT
- LSD (Limited Slip Differential)
- Quaife
- Miscellaneous
- Short Throw Shift kits
- Automatic
- B&M Shift Plus INFO (for late 06+, wiring is a bit different)
- Transmission Tune
- LSD (Limited Slip Differential)
- Quaife
Tuning: Our stock engine tune is rather conservative. Tuning parameters like power enrichment delay, air to fuel ratio, and spark timing will result in decent horsepower gains. Tuning after installing bolt ons (intake and exhaust) will further bring out the potentials of those modifications
- Tuning Equipment INFO
- Canned Tune
Legend:
>>= Link to product
Videoclip= video
PIC= Picture
INFO= Additional information on product
OK I think I got everything that wasn't added from the last thread. If you see something missing just post it up and I'll add it. Also if you have a video clip or picture of your exhaust that isn't already up please post the link and I'll add it.

try and get some brands for the STS
JBP has stage heads
LS2edit for ecu tune
for nitrous any of the brands, Zex, Vemon, Holley, etc. etc.
also Bassani makes a cat-back.
I know there are intake manifolds as well.
