What made you choose this particular product?

Other exhaust clips with this muffler on the 2.4L engine. I preffered a custom dual exhaust with two of these over pre made catbacks.

Is this your first time buying from this brand? Did you consider other brands?

Any additional comments?

Stock exhaust, cut a 12in section off after the cats which are gutted. Love the sound, love the look of the exhaust tips so 90% of the exhaust is still intact.
