4" exhaust.....quick question

975 Views 5 Replies 6 Participants Last post by  carnut57
Having installed a 4" system on a '97, I'm familiar with making extra space for the downpipe(bending/cutting the seam or bending the firewall) Any special "space making" work or other concerns with the SuperDuty and the 4" exhaust?

Also, any comments on vendors with well-fitting or not-so-well fitting systems?

Thanks,
cdv

No modifications needed on the Super Duty to get he 4" installed. As for fit sound and performance, the Banks Monster exhaust is one of hte best. I have it on my truck and really like it.
