Toyota Echo 2005 RS Performance Upgrade Help

[tarkus]

For fun I put a big ass performance muffler on my 2004 Echo RS, and was pleasantly surprised at the better low end power it gave, with no more struggle to accelerate on hills. In number terms the difference was probably quite small, but in driving terms it was significant. Fuel economy also improved, to my surprise.

what chip did you use? Did you have to change to a higher grade gas after that?
