For those of you that did 3" (or even 2.5") true duals over the axle, did you relocate that fuel pump relay plug mounted to the driver's side seat hump? I want to run one pipe on the driver side and one on the passenger side. The driver side is the one with the issue.

Its a set of 2 blue and white plugs. One plug comes from the fuel tank and the other goes to the front of the car.

If you did relocate the plugs, how did you remove them? Did you do anything to protect them from heat?

I've already modified the Panhard Bar brace for extra clearance.

 

I used zip ties. FYI, under the axle will get you a lot more power than over (No bends). I've had both.

 

why would mandrel bends create a noticable increase in power??

 

The exhaust guy bent mine almost 90 degrees to make a u-bend to go over the axle. Cut those off and went with straight pipes under the axle and it had a lot more power.

 

According to the butt dyno?

 

Technically, yes; but it was a MAJOR improvement in power and sound.

 

sound yes...

power...doubtfull

true duals over a single pipe catback is about 10hp on a decently modded engine....how much of that 10hp do you think you were losing by adding extra bends...2hp??

it was in your head
