i ordered DC 4-2-1 1 piece headers and im wondering if there are any tips or suggestions that u guys have for when i install them. i've installed an OBX 4-2-1 1 piece on my friends mazda and it wasnt to bad. just wondering if theres anything i might have troubles with or if there are some things i should watch out for.

thanks

 

pretty self explanatory. Start in the front, and work you way back, well thats with a cat back.
