I've been reading odd posts about a minor fitment issue. That is, the left (passenger) side muffler sits lower than the right and in additional cases off center a bit to the indentation in the rear bumper where the exhaust tip exits.

Always the left muffler.

I ran into this with my Rev II in my S4 TurboVert. I tried adjusting by taking all the slop out at the flanges to try and get it lined up, but minimal improvement at best. Finally I was able to get things to line up reasonably well by taking to a muffler shop and having them heat the pipe to soften it so I could create a bend by pushing up and to the left on the left muffler.

I just installed an Old School version of the Rev II (not stainless steel and smaller tips) in my S5 TurboVert and everything lined up perfectly with no adjustment.

My request is to everyone that has a Racing Beat Cat Back or Full exhaust, especially the current stainless steel version, that has experienced this fitment issue please replay to this thread.

Trying to determine if I and a few others were just unlucky or if something is indeed different between old school RB and new school.

Thanks

 

Mine does appear to sag a little bit, but I had some minor rear end damage that I attributed to the ill fitment. I believe mine is an older one, I got it 3 years ago on my donor car, so I dunno how old it is.

 

Mine is just like that.
I too tried to realign it by loosening/adjusting at the flanges- to no avail.

I've just been living with it.

 

ive always read that they only fit rite if u replace all the exhuast hangers i think its ritten on there site to not sure .

 

My TII Rev system didnt have any fitment issues.

 

I have the all stainless one, mine is not perfectly center, but I used all kinds of different donuts so I figured that was the reason.

 

You can get different sized rubber O rings and hangers from NAPA or Carquest. Advance auto sucks *** and overcharges for them. NAPA/Carquest will also let you fit it usually to make sure since they're in boxes.

Or you can use hose clamps if you're ghetto and want to save time.

 

Mine sits lower on the left.

 

Me too. I bent the upper hanger upward to help it a little.

 

kinda like this? this is my old revII system (new style), i think i had the same problem with the true duel set up on my na too

 

EDIT: RB True Dual.

 

thats what mine looked like on both systems

 

Underneath the car, not at the tips genius.

Mine does the same. I'm sure it can be corrected by new donuts, that would be the only reason for the twisted look.

 

Re-read the original post, Einstein.

 

That's actually not a bad idea, if one side hangs too low, you could just tighten up the clamp to pull that side up more. And it would be a lot easier to install than those ******* exhaust hangers that suck major dick and only exist to cause pain to the exhaust installer. Only downside I see is more noise/rattling, and possible failure of the clamp under harsh underbody conditions. How long would an average hose clamp last underneath a car?

The exhaust will not vibrate enough to cause rattling with the clamps, there is also no way in hell it weighs enough to be able to break a decently sized clamp. I run them on my car. The only con is extra stress on your metal hangers caused by harsh vibrations from jumps or taking speedbumps at speed, anything that can shake the exhaust enough to momentarily loose support from the clamps. How significant that stress is, is up to you to judge. I'm not worried about it but I'm sure people will chime in and tell you how horrible it is.

I have had four rubber exhaust hangers fail on me in the two years that I've owned my car, they crack very easily and the heat transfer from the mufflers makes it worse.

 

Had a true dual rev 2 on an 89 vert, no fitment issues, using the stock old *** exhaust hanger donuts.

 

No, it can't.
The rubber hangers just stretch.

 

**** ur right dude, my left muffler hangs off center too the left and lower

 

Yup, when I had the system on the our '89, I had a shop heat and bend the hooks to adjust the left side into position.

 

I have the catback setup and my left one sags.
Thanks Robert

 

HOZZMANRX7, I posed this as a question before. Here Is the thread.

So, that's 13 with this left side sagging issue noted within 16 hours of my making this post.

To clarify, I'm not talking just about the left can. I'm also talking about the Y Pipe. Mine hung so low that it was occasionally catching freeway junk and it getting trapped between the pipe and pavement. Much better after a little heating and bending, but still lower than the right side. Like in Travis V's photo in his response.

Keep the responses coming.

Thanks

 

Fail times 2 bud.

I know what you mean about this whole issue, it's soooo ugly to look at the car underneath. Not only are you looking at that slant on the exhaust but the gay little spare well that droops down and makes the car look like a pieice from behind.

Might I add, on my install I lost the bolts to hold the donut for he y-pipe up, so that could also be the reason possibly for my harsh sag. I should probly install that this winter while its in storage.

 

I reused my donuts.BUT,I put some worm gear clamps around them.It improved the Height.It was off on one side.
The exhaust was also not in alignment Tip wise.(one tip was out more than the other),But I could live with that. I attribute that to "eying" up the Turn in the pipe off the Presilencer.
I am running a Pacesetter Header to a Homemade Presilencer.
The rest is a RevII (tii Exhaust) on an N/A.Sounds loud..I said it SOUNDS LOUD!..(j/K!)
