I was going to say "3 inch for an 08 lancer? Thats totally going to rob horses like crazy, theres no backpressure". But then i went back and saw you're turbo'd Good work man. Looks great!! I'm a full proponent of custom exhausts. A lot of the time you can find shops that do mandrel bending, and still pay half of what you'd pay to buy an off the shelf exhaust. When i had my boosted 03 OZ i had a local shop make me a 2.5" mandrel bent exhaust section from the turbo outlet to the magnaflow cat back. Cost me like $100 total and it definately was felt on the butt dyno.

 

what if you get a under car mufler and have it come out as a chrome tip

either way looks good you gonna get some clips of the sound for us?
