Maybe gave a bit better low down performance, but nothing top end............... Yea the secondary pipes do look a little shorter then the primary pipes but the 2 pipes colect at the cat like the pacies. my only consern is that the hego sensor is only in the secondary pipe about 5" from where they collect.so its only getting a reading from the rear 3 cyl but the only difference in performance is that the engine pulls harder from 4000 rpm to about 5400 rpm with a little bit more responce .but it also got a 2 1/2" cat at the same time as the std cat was only 2 or 2 1/4" and very rattly.. with the std headers it would start to run out of puff around 4600 rpm and only rev to 5200 rpm. but im still happy with the result..

i have the same genies on my car and haven't had a problem i put the 2.5 mandrel bend exhaust on then the headers a couple weeks later just to see if they would make a difference and they did make a fair bit down low and slight difference up top.

The two pipes join in the flange at the bottom of the picture you posted then run a single pipe from that to the cat. The cat with genie's is generally positioned alot closer to the engine. The pacies have long secondary so the cat can be mounted back which improves low down torque. My genies had a the same oxy sensor pickup, I took it back to shop and told them to plug the hole and weld a nut on the single pipe just above where the cat joins. When Paccies are fitted, the price includes putting 2.5in flanges on the factory ford cat. |
