Anyway back to the topic.
may I suggest doing a custom exhaust from a muffler shop. It's alot cheaper.

I was emailing one of the guys from SpeedCorps

heh i talked to him last night and he said he wasnt sure :-/ guess he doesnt like me.. haha

Tanabe is in the final R&D stages with their exhaust for us.

This low and high speed mode is a a mivec feature right? It adapts to your driving style and runs the engine at the peak performance for that style? I had an 04 Dodge Neon that would adapt to my driving style, then negate any aftermarket mods, to adjust the hp to a constant. Basically any bolt ons would be useless after the computer realized it was there. Does mitsu incorporate this into the PLC? I only ask this cause i recently installed the Greddy Ti-C and noticed some difference at first, but i dont know if i got used to the feel, but the car seems to have lost some edge...

PS. Sucks to have an aftermarket muffler when your car is revving at 2500 at a stop light... Damn computers

i installed a tsudo, and I didn't notice much at first now I feel it big time...second gear puts you in your seat!

OT but i feel the mivec big time right before 4000 RPM. All i have is a custome CAI, Light weight crank pulley, and custom 2.5" exhaust to a 4" aftermarket muffler. (christmas present... had to put it on but sounds suprisingling bada$$)

Ok back to the topic. I'm not going to lie... the 2.5" piping and my 4" exhaust did almost nothing for my low end. but from 60-115... WOW it is really crazy how much it helpped.
