I'm in the process of buying a weaponR headers for my ge8. I have some questions though..

What is the difference between the Race and Street headers in terms of how it looks like? Can someone post a picture of both headers.

Is there really a chance of CEL to appear when you use a WR race/ street headers?

Do you feel vibrations underneath the car during idle/high revs?

The so called "popping" sound or backfire or whatever, does the so called sound becomes louder when you install the headers using a stock midpipe and aftermarket exhaust or it really depends on your midpipe setup (for example removing the oem resonator or changing to a bigger pipe diameter. What's causing it to Pop? The cat converter removal?

Do you really need to have the car tuned or do you really need to use a piggyback to elimitate the loud popping sound it creates after the installation?

Lastly, is it worth buying? For the price and the performance gain it provides? I mean is it a good upgrade for the ge8?

Thank you

 

Sorry mods i already posted this on the main exhaust thread we can close/delete this one instead. Thanks
