MEGA: Aftermarket Exhausts

Did the GHL have a cat on it or not?
That was alot louder than i expected.
Sounds badass, but a bit too loud for my liking.
 
I've tried 3 downpipe/back exhausts last friday on a Dyno .... here are the results

Mod's :

CAI Injen
FMIC Turbotech

Exhaust line made by muffler shop downpipe/back (suposed to be hi-flow , with cat , resonator , dynomax muffler)

Exhaust line made by Turbotech downpipe/back (2.5 inch 304SS , mandrel bent , with hi-flow cat , resonator , muffler)

Exhaust size

Hi all, I am totally new to this forum and driving a humble 1.6L 2001 protege.
I intend to change my stock exhaust. Can anyone advise wats the size best for my car?

Stock
Current header piping size= 1.5"
Current down pipe size= 1.3"

I understand that too big will affect performance instead, so came here to seek advise.
 
Turbotech?? Who where and how can I get in touch with them. Those are some kickass #'s.


How much is that exhaust? We should try and set this thread up like the SMIC&FMIC info thread. Info much more accessible.
 
alrite, im getting a 2.5" exhaust sytem, but i need to find a new muffler.... any suggetions, 2.5" inlet!!!
