Dynomax turbo muffler and walbro 255hp = good buys for the money.
 

I just installed a dynomax muffler turbo series, the one made for the turbo eclipes gen 1. Good ---- for a cheap price. It quited down the exhaust alot. Also the walbro 255hp fuel pump brought my car back to life. That stock d15b7 fuel pump could take the dsm 450cc injectors and my uberdata fuelmap.
