As many people asks about the basic mods, I've compiled a short list of positives and negatives for the "basics." Add to the list as necessary.
Exhausts: Buschur: + Good quality and gains and you can pick between a quiet or loud set up. Available with 3 different mufflers.
- Heard it doesn't sound as nice as many others. The new Buschur exhausts are supposed to be better.
Buschur Racing -
Works: + Great quality, great gains and a lot of detail to sound level and quality. Offered with the Exhale or Steathworks mufflers..
- $$$$. Works parts are expensive but you're getting great parts and service.
WORKS-
Greddy: (Racing Titanium)
+ Lightweight and great gains.
- Loud as hell and a higher pitched sound as titanium resonates at a higher frequency than steel. $$$.
Greddy-
JIC: (DE Type 1) Same as Greddy. Also available in SUS, SUS/Ti combo.
JIC-Magic
Fujtisubo: (RM01A)
+ Great gains and very quiet.
- $$ and hard to find.
Fujitsubo -
Flash: Dynoflash: + Cheap and proven gains. Also no dowtime as he does email reflash as long as you purchase the cable to connect a laptop to your ECU.
- Service can be delayed as Al is a one man show and very very busy.
Vishnu: + Shiv knows his stuff and expect great gains.
- $$$. One of the most expensive mail in flashes out there.
Works: + Conservative but the reason being they wanted to add a buffer zone for everyday reliability. Traded peak #s but they did it for a very good reason. No MBC needed as they addressed the boost issue with their own boost line w/ restrictor pill.
- Won't get the highest numbers and is $600 for the flash. Again it's for a good reason.
Filter: (Several members have confirmed no need for a tune with these filters for problem-free idle/driveability. Of course a tune will make these part put out even more power) Buschur: + Open cone = more flow and better gains. Don't need a tune for your Evo to run properly. Great for those people asking about "How do I get that WHOOSH sound from my Evo?"
- You'll hear your BOV to a greater extent which can get extremely annoying.
Apex-I: + Best filter on the market for filtration and performance. Dry filter so no need to worry about oil screwing with your MAF sensor. Lifetime filter w/ no maintenance.
- $$$. Expensive filter. You'll hear your BOV to a greater extent which can get extremely annoying.
Works: + Stock look. Better flow and filtration than the K&N with no annoying sounds of the BOV.
- Drop in so you won't get the gains of the open cone and $$$. Oiled filter. Maintenance every 15K miles (washing and re-oiling of the filter).
K&N: + Cheap and you get some gains. Stock look and no BOV sounds.
- Oiled and filtration. Maintenance every 10K miles (washing and re-oiling of the filter). Drop in so less flow than open cone.
MBC: (With all MBCs, you'll notice boost spikes higher than your setting on days with extremely low temperatures. Just turn down the boost a bit and you're good to go) Buschur: +Built from a company that really knows their stuff when it comes to the Evos.
-Not enough reviews to judge.
Forge Motorsports: +Click feature on the adjustment knob and a high quality piece. Won't be disappointed.
-Some members have had slight problems, but Forge has been very good about customer service.
Hallman: +Another well used and known MBC with very good reviews and satisfaction.
-Haven't seen a downside yet.
Hope this helps you out. Good luck to you with your Evo mods.
