I was wondering if when Installing one should I get the outlet and Inlet the exect same size as the stock pipes or go a little bigger. My stock pipes are 2" and there are options to buy 2" or 2 1/4" glasspacks.
Thanks

 

I am not a huge fan of those mufflers to make the exhaust louder. I like to keep the car in stock setup.

You might want to post this in the headers, intake, and exhaust section, because I have no experience with this stuff.

 

it makes no difference. may cost more to have them welded on if you get the bigger diameter bc they will have to use a reducer to fit your stock exhaust pipe.

getting those only make your exhaust louder, you will gain no performance from this.

get a full catback system
