If your car has an axle-back flange, this will fit your car. It is primarily for the Aveo. I paid $30 dollars to have it made. Bolts right on and has a hanger to adapt to factory hangers. You can adjust the pipe mid way to bend to your needs. You can also adjust the hanger. The intake is also short ram home made. With used but clean conic filter. This has actually got me from 18.7 second 1/4 mile to 17.6. Beleive or not. Sounds awesome too.
I also removed all seats except for driver and ran all runners in intake manifold. It might have been colder too im not sure. Not sure what to tell ya. I was suprised. But hey the stuff is for sale. Dont be a lamer.
what is wrong with your Aveo, the Aveo avccording to car and driver runs 17.4 stock, I ran a 17.1 with mine stock. you should never be in the 18's. do you have a pic of the muffler?
I can get a pic if you are seriously interested. Its a straight pipe. Is yours a manual or auto? Mines a manual. And it runs 18.01 consistantly stock. I know how to shift. THe track i go to is slightly up hill. But not by much.
