ok, when i began with my dual exauhst research this year i knew that i wanted dual exauhst for the "look." and well on the other hand i didnt want to lose performance. I know that the celica isnt a race car, but lets face it, im sure that everyone is conserned with performance as well as looks. and after thinking about it, 15lbs doesnt really hurt you that much unless your going to the drag strip like lucky every weekend. i mean, just go on a diet or somthing and your ok. anywayz, what i did is run two dummy pipes. My exauhst actually comes out from the middle of my car. i can show you how it looks at the meet pesk, and i can get the job done cheaper than you might think. i dont have updated pictures of the install, but i am sure that i am not losing power, i have the look i want and ok, my car wieghs a couple pounds more..big deal!
