I will be completely honest with you, this is not an hard job, but it will indeed test your patience. You will get scrapes on your forearms, you will scratch up your hands, and you will have to work with very little space. If you’re okay with that, you will be able to get this job done. Installing long tube headers on any vehicle that doesn’t have a lot of space will be challenging, however the results will be worth it in the end. You will get a rewarding feeling after accomplishing this DIY.
After putting both manifolds in with the O2 sensor extenders, I didn’t really notice anything out of the ordinary under 4000 RPMs, however when you let your engine scream out to redline, you will be rewarded with an amazing sound and feeling that cannot be expressed in words. The only way that I can describe it, is you will be grinning from ear to ear, until you shift into a higher gear, and then that grin will get bigger.
