Borla has two part numbers for NA exhaust. One is substantially more expensive
What the difference?
The first part#140083 is $759 and is cat back
The second is part#1014003 is almost $200 more but had no description.
Secondly, there is a resonator that on my first coupe I installed but wasn't sure if I should have. What does the extra resonator chamber do? the factory exhaust didn't seem to have that, that I remember anyway.
Are there any headers for the NA and are they worth it. Ease of install? Looking to do a complete exhaust right this time along with a Eurocharge tune and my Renntech airbox should yield good results. Opinions please.
What does the resonator do?
