Honestly, with your mods either would work, if you think you may do more engine work in the future, get the RMW and you'll never have to worry about an upgrade, otherwise just do what your wallet says is best for you.

As for wrap, I wouldn't.
The only time I'd wrap something is if it was very exposed and easy to get on and off.
Wrap collects oil, oil catches fire, so unless you have no leaks and never will have, or can easily get to the wrapped item to carefully watch it and re-wrap when needed, go with ceramic coating or nothing.

 

I did not use any copper spray. Everything matches right up with the gasket perfectly.

 

I just got my RMW street header with a Milltec exhaust. It seemed to 'open' up my engine and resulted in much more balanced power. At least according to my 'butt' dyno.

 

As far as the Copper Spray it's one of those "shouldn't need it" items, but won't hurt if you do.
Most of the brands of gaskets hold up really well and can be reused, then I'd spray it for extra sealing, but it's not necessarily on a new one.

 

Yes dropping the subframe is a great idea as even a 1/4" makes all the difference in world.

 

RMW shorty not wrapped.

 

Use Remflex exhaust gaskets. (Amazon)

They are thick, compressible and do not leak.

Thinking that Jan went to ceramic coating on his headers.

I looked into all that when I put my mine on and decided to just put it on right out of the box. If tracking the heat may be of issue but for street and the occasional mountain run could not justify the cost. From what I researched the best stuff is the white heat coating from somebody like Swan Tech.

 

I did mine on jack stands but I used some solid 4" blocks to put the jack stands on so that the car sat even higher up. I had to remove the heat shields that travel up toward the power steering and coolant reservoirs. Would think my 4-2-1 is a little bigger than Jan's 4-1 as well.

A few chosen curse words and then some prayers got the sucker up in there.

 

I took the easy way out...muffler shop here we go. They did a great job. Actually, DT installed the header and Flowteck exhaust installed the 'Milteck' exhaust.

 

Milltek #1

 

I bought those gaskets for my Milltek - don't fit, had to throw them out after trying to cut to proper size. I ended up using what came with the Milltek. The holes are too far apart to fit on the stock header at least, and that graphite cannot easily be cut to fit. Need a punch like tool for that. Maybe this fits on RMW stuff.
