I need to replace the exhaust manifolds and risers on my boat. I know I can get factory ones but has anyone used after market ones that are better. Just figured I might upgrade if there is something better out there. 2005 5.7 OSXi motor. Thanks

I currently have Barr manifolds and risers with no complaints. I have also had Sierra's without any issue. Bought them through Ebasicpower.com.

Back in 2017 it was $589 + $79 shipping. (that was for the early GM style)

I have never used them but based on the horror stories I have read I would stay away from GLM.

I’ve dug deep into the forums on this. My engine 5.7 gsi. Throttle body... I’ve ran Sierra and volvo. Strictly salt. No closed cooling. Religiously flush with fresh water as well as vinegar .... and to be honest neither stands out as the best... both have shitty paint that will rust after one or two trips. What ever I buy sand the mating surface with a true block and coat with a few light coats of paint... ball park 3-5 years on each set I have tried. Hope this helps
