As someone that’s had leaky headers hydrolock an engine and have read of similar issues with just the risers I find the value in the KE units a value in peace of mind myself. Headers have proven to largely be a waste of money performance wise unless you’re pretty deep into the engines but manifolds with SS risers also have issues. That’s just my pov and not nearly as relevant until you’ve lost an engine. No guarantees but it will send you looking to improve the odds.

One month later and they still being machined. Then need to go to powder coat. UGH... This is getting really close to boating season. And I still haven't fired up the new engine yet because of the exhaust.

After speaking to Bill again., it's looking like the TnL exhaust might be arriving in June. So I found a set of CMI Fusion headers in stock and bought them. Hopefully I'll be on the water by Memorial week end.

Still trying to decide if I should cancel the TnL order or not?
