Has anyone done the Borla mufflers on a 430 and I assume a 400 would be the same. What I want to know is the Borla system a direct bolt on to the flange at the end of the rear pipe or do you need to have it welded. Thanks in advance for any help..

 

i just had mine put on and it did not need any welding. it was a plug and play type of deal. on mine, the right side muffler kinda sat lower than the left one did, so he had to weld something in order to get it in the right place. but it is easily removable, he explained to me. hopefully this helps.

Mayur Patel, Thanks, so I guess they are a bolt on application. Do you like the sound and where and how much were they?

 

HD, fyi there is a group buy going on for this. Please see the original post for details.
