Will these bolt straight to my existing exhaust system?

These mount at factory attachment points. You'll need to confirm your current downpipe or cat-back configuration fits the header outlet before final assembly — outlet diameter and angle should match your existing system.

Do I need to do anything to the headers before installation?

Inspect all mounting points and runner welds before bolting on. If you plan to wrap the tubes, do that first — it's easier off the engine. No coating, primer, or painting is required on stainless.

What if I have a fitment issue when they arrive?

Test-fit the headers fully before you tighten everything down. Check clearance at heat shields, firewall, and steering components. If there's interference, contact support with photos before proceeding — some fitment tweaks may require minor bracket adjustment.
