They look like chrome to me.

Yup...chromies. I actually loved the old tips (circa '93). They looked a little more classy with the slash tip.

 

They're stainless. I discolored mine after driving hard a few times.

 

They're..... beautiful... lol.

 

Stainless. I cut a set off when installing a powerpulse muffler in an RX-4 wagon. I had to extend the pipes 1.5'.

 

ya sure?!? heavy wall steel construction as per web site....almost postiive the tips are not stainless.

 

I'm pretty sure. They consist of low grade stainless that is very thinwall on the outside and an inner soft steel pipe about 1 3/4" of medium wall thickness.

Nothing on the muffler itself is thickwall. They come from Italy and the pipe is .063" medium wall thickness on the input side of the muffler. Only the center section and header are thickwall .120".

 

I like those tips. I'm not a fan of the older angle cut tips. Looks really good Ray!

 

Yup those are the ones I've got on my car, and Marc has the old style thin slanted ones. Once his car is on the road I'll post comparison pics.

i got mine around january, and they look really pretty. Sound good too.

 

They look real good! I saw them in person. Ray revved it to about 8k ( I think on accident) and sounded realllll nice! Not as loud as I would like, but then again I run 2 flow through Borla's...


VERY nice btw!

 

If Jeff says so, it must be true, but they sure look shiny for stainless! I think I'll just pretend they're chrome.

 

I still have the two tips I cut off. They're just sitting here. They are definitely stainless. Infact as I cut them, one was a little longer than the other so I trimed it down to match the other. It left a 1/4" piece so I wanted to see whether it really was stainless or just chrome plated so I left it out in the rain for several months.

It developed a little bit of tiny rust spots which could have simply been the splatter left over from the cutting process because I used a cut-off box which is a giant abrasive disc and resembles a miter saw (for those who took woodshop). It sends a shower of sparks as it cuts. I'm sure some of the mild steel of the inner pipe got on the stainless outer pipe and then rusted out in the rain.

Or perhaps the tips are a low grade of stainless (like what's used in Magnaflow mufflers lol like 409 or whatever) and the rust I saw was a natural product of the intense heat introduced into the metal during the cutting process, which is many times higher than it would ever experience as a muffler tip, even on a rotary.

Either way, I'm sure the new style straight cut rolled tips with the inner pipes will look good for many years and should not rust on you under normal useage. Being stainless, as I suspect it is, you should be able to keep them looking nice for decades with proper care.

 

Word...

 

Thanks for the inside technical scoop Jeff, I'm sure you are right, they are stainless of some sort. Just that I've never seen stainless be so shiny!

In any event, I think they are great, a faithful copy of the classy originals only better. And that RB sound and performance is all pleasure.

 

Here are some pictures of the angle cut tips on the older RB mufflers. This one is for a 79.

 

This has slant cut tips. They tucked perfectly up to the ground effects style kit.



I kinda doubt the new straight tips would fit as cleanly. This is not a concern with a stock rear apron.

 

lower grade stainless will rust too. Plus its probably cheaper to use low grade stainless than go through a chroming process. Less labor processes.

 

low grade stainless. you have to clean them often or they will rust quick like... i have the old school slash tip. I love the way they look, but hate the way Rb exhausts flow. LOL!
