• The site migration is complete! Hopefully everything transferred properly from the multiple decades old software we were using before. If you notice any issues please let me know, thanks! Also, I'm still working on things like chatbox, etc so hopefully those will be working in the next week or two.

Exhaust U bend



Nit really looking for the most HP gain I'm more worried about airflow and better gas mileage. Thinking 2.5 with hfc or maybe stock cat.
 
I just replaced my stock downpipe w/cat with the 2.5" unit from ZZP. Much better than stock and cheaper than the local muffler shop. They wanted $450 just to weld in a new "factory" cat, I got the ZZP unit for around $250 and it was a 30 min. bolt-in. IMO if you're going to stay close to stock then this is the route I would go. If you are going to do serious modding then go with headers and 3" out the back.
