4" exhaust.....quick question

976 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 need to modfiy on the 99-up with a 4". Fit maybe a bit tight, just make sure you align before you tighten the clamps.

I have installed Summit, JEG's, MBRP, and Magna Flow, and none had any issues.
