What owners say
These arrive on time, boxed well and in good condition. Reasonably easy to fit and they did fit well and attached to the new exhaust at the right position. They look good and sound great with plenty of snap crackle and pop
Pete Mac
Ve ss ute full xforce 3 " from headers Very happy with service, product is great and nicely finished. Removed xforce headers and cats and installed tripple stepped headers with 3 inch cats. Look great, fitted with no worries what so ever. Sound is great, sounds so clean and refined but yet still mean. Love them
Jared Stevenson
To all the team at GM Motorsport and Ramjet, thank you so much, from Bastain and Cody for all the many phone calls, through to all the mechanics, and finally Phonsey for dyno, it’s running the mighty chopper Reed cam with cnc heads with ramjet otr, 2 1/2 x force exchaust and best sounding headers on the market ramjet triple step headers, if any of my mates want their Holden or ford engine work done, GM Motorsport are highly recommended.
