Considering changing my headers. I've done mods myself but never headers. Can I get away with using something like Race Ramps for 7" of clearance or will I need a proper lift? Also, is it possible to do it with wheels on or do you need them off for proper working room?
Did a search but didn't find much definitive. I did find some videos that make it appear possible to do this with wheels on and minor clearance but wanted a better consensus.
Dang, gotta take the wheels off for Dundon? Good to know, thanks. I’m totally dreading my 1st centerlock encounter. I’ve got all the Dundon intake and exhaust parts sitting in my garage for months. Procrastination’s a B**ch

I have a set of Akrapovic headers and the installation manual is the best I have found, it is available on their site.
If installing Dundon Catted headers, wheels must be removed, to be able to tighten the O2 sensors, but all other headers don't need wheels removal.
The Akrapovic manual has the tightening torque for all the bolts and a tools list too.
they retain the factory side mufflers, very OEM replacement like, so the cats bolt to the side muffler, no wheel removal needed, prob very simple and fast. you tube it
Wheel removal is not necessary for installation of the headers. This was done on the lift at my house so I had a lot more clearance than 7" ramps but I don't see a reason why you would need to remove the wheels to tighten the O2 sensors on the Dundon street headers. The O2 sensors can be installed and tightened from below and are located towards the bumper not the wheels.
Images below to show the wheels were on the car during the install of Dundon Street Headers.

No wheel removal necessary. I removed the bumper and side heat shields - easy to do. Made it easier for me and less prone to mistakes or wrestling with things. Make sure you properly torque bolts in a pattern that evenly pulls the headers onto the head gaskets. Also make sure you lube the nuts on rear muffler before removal (wd40 is fine). They are prone to stripping. My only advice is to take your time and do it methodically and carefully. Great time to do the plugs while in there as well assuming you have some miles. I think torque on the plugs is 22lbs if new and 19lbs if reinstalling existing.
Thanks everyone, I will do the plugs while I’m in there. Did anyone do the Dundon plenum / TB install themselves? I’m wondering how exact you were with and where did you find torque specs, especially for the engine bolts?

I had the plenumbdone by a perfectionist. I did the headers using all factory torque specs. It’s a precision machine and should be maintained that way.
