Hey everyone, so i live in norcal, and of course, smog tests are very strict. I really like the sound and the gains from the ppe headers, especially with a f sport exhaust. I just bought my car a year ago so i dont have to smog for another 4 years, but when the day comes, is it possike to take out the long tube headers with stock manifolds and cats or is there wielding involved and i need a new set? I'm new to this modding scene, barely know anything about exhaust systems but know the basics haha. Thanks!

 

Depend if your doing the work yourself or paying someone. Its a good 6hr process in and out. The header is a straight bolt on. But when you take the oem one out the primary cat goes with it. As it a one piece item.
