Would just replacing the stock muffler rather than using a cat-back give identical or similar results? On a 2014 hatch, thanks guys.
I have the J2 Cat-back kit, from ebay. 379 shipped. full bolt on exhaust, did it by myself with floor ramps. definitely adds power and sound is pure bliss. Best thing i've ever done. Look around for different brands like FsWerks or something to your liking. I was gonna go with the Race exhaust but it was sold out and i got the J2 in 4 days.Sound is a plus but I'm looking for performance. Thanks pvtbclark that's all I wanted to know. Do you have a kit our custom made exhaust?
More noise or just a different tone? That's unlike Borla to put out a product for more noise.Check utube for some before and after dyno runs with exhausts..
So matter, some do not.
Some cars gain HP, others do not.
The Borla cat-back adds ony one hp to the ST.
But it sure makes a lot more noise.
Well the utube vid I watched had the Borla install, then another part the dyno test on a ST.More noise or just a different tone? That's unlike Borla to put out a product for more noise.
The whole curve ranged from a slight loss, to no improvement to at most one hp up.try to find dyno charts of before/after the cat-back installs. true some systems only gain a small amount overall, but look at the curve and see where the additional power is available, e.g. it might only gain 1hp over peak but there might be a considerable difference in the typical driving range.
