it depends if you are talking about a cat-back there is no difference exept for sound. If you are looking at headers cobb has a better performance because it is using a equal-lenght design. People always cobb is better blah blah but the difference is small.

1, the difference isn't that small, the cobb setup gives nearly double the gains at peak power, not to mention the gain in midrange torque over the borla's that you'll feel everyday, oh and those numbers are including adding the random tech cat to the borla header

so, 650 for a base no coating, no cat cobb header, or ~650 for borla headers and a random tech cat that doesn't give the same power, sure its stainless, so pay the extra 200 for the coat and/or 100 and get a cat, in then end you pay 650 to get 6 whp peak gains, or another 300 on that to get ~10 whp, same bang for the buck in terms of peak power, but again, dyno'd, the borla/RT combo gives 6.5 ftlb average gains from 2000-4000 rpm, the cobb combo gains 13.5 ftlb average over stock for the same range

so yeah, theres a price difference, but theres also just as much bang for the buck performance wise if not more with the cobb headers

"For comparison purposes, the latest generation Borla header with the Random Tech cat using their newest high-flowing Metallic Substrate cat produced 132HP @ 5400 RPM and 149 ft-lbs @ 4000RPM. The Borla/Random combination proved to generate a decent peak HP figure but its average power was significantly lower.

Measured between 2000 RPM to 6000 RPM, sampling every 100 RPM, the COBB header setup produced +9.4 HP on average and +12.7 ft-lbs of torque on average. The Borla/Random combo produced only +5.5HP on average and +6.9 ft-lbs of torque on average. This represents a 71% higher average HP gain and an 84% higher average torque gain with the COBB header compared to the Borla/Random combo.

The highest gains recorded with our header were +14.7 HP and +17.5 ft-lbs torque. Nowhere in the power band did we find a reduction in performance. In fact, low-end torque was significantly improved. At 2000 RPM, our header is making +16 ft-lbs of torque compared to stock. FWIW, the Borla/Random combo produces +1.9 ft-lbs at 2000 RPM. In fact, from 2000-4000 RPM, our header showed an average torque increase of +13.5 ft-lbs whereas the Borla/Random combo showed an average torque increase of +6.5 ft-lbs. This represents a 107% higher average torque with our header compared to the Borla/Random combo in the portion of the powerband we use the most."
