Custom Catback drawbacks?
i'm pretty new to altimas and 4 cylinders, but i was wondering if there were any drawbacks to getting a custom catback with 3" piping as apposed to the stock 2.25 or 2.5" piping on my 2.5 sedan. i'm eventually planning to go turbo but for now, i was thinking of having this catback made. i was quoted for about 450 by a reputable shop here in southern california. so to simplify:
1) 2.5/2.25 piping vs 3" piping?
2) price? (if anyone here in socal can point me to a shop with a better price pm me)
3) worth it? (yes, i know the car is a 4 banger, i dont really care about that. im asking if the price justifies the gains)
