Im thinking of doing headers on my truck and i ran accross a local deal for some headers for 400 brand new Gibson im gunna try and get them down to 375, just wondering if the JBA and Gibson headers are comparable or if one is way better

 

You'll lose a lot of low end torque. What wrong with the headers on your truck now? Just wondering...

 

headers are best kept for boosted trucks. The OEM headers and cats will flow that engine at 5 grand no problem. if your looking for some pep, take that cash and gear your truck up one set.
