Great plugs to gain clearance

These plugs are the only performance plugs I use to gain clearance from the headers, besides them being Accel brand.

Great fit

Ordered these headers for my 04 Gto that I ls3 swapped and they still fit perfectly and sound a lot better than my stock headers with a cat delete. Getting it tuned next week will see how they perform then

I am very impressed with the quality of these headers, especially for the price. I have purchased $500.00 headers that don't look as good as these do. Excellent product!

Item looks good but have heard after buy that manifolds will not hold up to their black color after they are mounted and use. I am hoping that this is untrue. We will see

Berry Performance Sales

Best deals around. Saved a lot of money compared to buying from Summit Racing or JEGS

Berry Performance is always on top of customer service. I feel like I am talking to a friend instead of a agent

Jeffery

Best customer service ever.

I don’t think you’ll ever find customer service that’ll beat Berry’s. Most down to earth and helpful people I’ve ever spoken to. I’ll always shop here and know I’ll be taken care of! 10/10!

Ordered smaller 1 3/4 headers on accident, I messaged them, they responded within a couple minutes. Helped me upgrade to the bigger 1 7/8 in headers. Super good customer service! & headers fit and sound great!
