I'm trying to build a relativily cheap exhaust that looks stockish so I won't get pulled over for it and it also relatively quiet on my turbo 2. I'm sick of getting pulled over for the fart can on it and the fact that it is annoyingly loud. I know rotarys are known to burn out some muffler elements because their exhaust is so hot. I was wondering what combos some of you guys have made for custom exhaust that have worked like this and also wondering if this muffler was pretty good and held up well and was quite. http://www.jegs.com/i/Magnaflow/642/...oductId=751042
Any suggestions and ideas are great. I know the Racing Beat REV TII is the best system to go with for this but its just not what I want or can spend right now.

 

"best" is a subjective term, but indeed the REV TII is a high quality system and holds its value well compared with other exhausts. The muffler elements that usually burn out is fiberglass packing, you want stainless steel packing instead. idk about that any particular mufflers as I myself run the REV TII system.

 

Ok cool. That helps point me in the right direction some as far as mufflers go. Thanks. I just can't find wanting to drop $900 on an exhaust before shipping right now for the REV TII.

 

yeh i realize i have a na but i just use exhuast tubing from oriellys and used ebay burn tip apexi type aftermarket mufflers, with flextubing to route from the stock y to the mufflers, sounds nice and quiet with the mufflers presilensers in, and without them thought im told i sound like a jet, but i have tested this sound theory and maybe the cops arounf here dont care but i rev it pretty high at least 5k when normal driving and cops outside there cars barely look my way...and i no longer use the silencers because it makes it funny sounding...(more like a piston than the sweet sound of the rotor pulses)

 

In the past, Ive used two magnaflow center-to-center straight-thru mufflers with a custom Y-pipe behind a glass-pack resonator (big mistake) and a cat on an NA and gotten the sound down to a reasonable level, with stock appearance. About $350 with mild steel components. lasted 8 years except for the glass-pack, but the mufflers were great.

My S5 TII has a full-custom single-exhaust with two 3" magnaflow stainless straight thru mufflers in series (no cat or resonators) - I get a lot of compliments on sound, and its not loud unless I jump on it. This system is all 3" mandrel-bent 304 stainless and it still cost under $850 a few years ago. However, if you dont want the highway drone noise, you're probably better off with something other than the straight thru mufflers - like a turbo-style oval muffler. Trouble is trying to fit the ovals where the stock y-pipe went...

 

Rotary Performance's Exhaust is pretty stock looking and from their website it seems to be pretty quiet. I have no experience with this but it looks close to the REV II.

$395. This is a cat back system~

 

^^^ that is probably a bit thinner and lighter than the REV II, however I had a system on my car that the PO had installed that look almost exactly like that minus the paint and it was decent.

 

That does look like a decent system. I had forgotten about it until just now haha. How big is the piping though. I didn't see anywhere it said on their site.

 

are those stock mufflers? since they look espically similiar

 

I run a high flow cat, resonators, and stainless magnaflow mufflers on my T2. I get compliments on sound and it's fairly quiet.

 

Which mufflers did you use? Did you do dual exhaust and how did you do the tips at the end? Did you just use the mufflers for the tips?

 

It says right there ;p.
RP 50mm Cat-back - 86-91
50mm = about 2 inches.
You can always call them too if you want the specifics~

 

Hmm. I dont know how I missed that haha. Thanks I see it now.

 

Just the standard Magnaflow Stainless 2.5" tubes. And yes, dual exhaust. And yes, the mufflers are my tips.

 

here is my recipe...

buy the RB 3" DP, its $140, and its a bolt on.

buy the RB 3" turbo back/rev II presilencer. its expensive, but it WORKS

buy 1 flange for the revii ssystem.

pick the rear muffler of your choice, go to muffler shop and have them make the pipe from the presilencer to the rear muffler.

done!

we've done a bunch of cars like this and with the RB presilencer they ALL have been pretty quiet. you could probably even keep your fart can.

 

This sounds like it might be the way I go. I hadn't actually thought of this idea but I like it.

 

i think that RP exhaust is a renamed dynomax exhaust. they look exactly alike and price is almost exactly the same. and the dynomax doesn't come painted like that so thats what your friend could have.

 

we've done a few cars like that, it works. it even shut the NA race car up

 

hmm sounds good. I believe that is the route I will take. it makes the most since.

 

ebay downpipe, borla xr-1 3" midpipe, run that to two cherry bombs and borla/magnaflow turbo mufflers. cheap, quiet, and flows great. have it rigged up at an exhaust shop. crush bends who cares. most people have to port their wastegate. stock turbo-stage 2 wont need more than this.

 

If u want real cheap, just get 10 feet of 3''(or whatever you want) pipe, and make it urself.
and just buy whatever muffler(s), resonators, test pipe/cats u want from ebay.
only other thing u need is a cutting wheel, grinder, and welder really, my friends dad let me use the stuff.

i spent a total of $80, and made an exhaust with less restriction, and less bends then ANY exhaust sold. Ive also made more power with MY exhaust then any other one ive had.
i know thats not what ur looking for, but with a built ex. u can tailor it to ur liking.

you could make it as quiet or whatever, as you want.

my 2cents: ALL ex. are way over priced, you can build one for a fraction of the price, and get EXACTLY what u want.

 

^^ Did you not use U-bends or anything?? Just a bunch of straight pipe?

 

just straight pipe, i cut on angles and used space pipe slices to fill gaps.
came out a whole lot nicer then it sounds.

ill take some pics of it this weekend.

i used 2 45* mandrel bent pipes for the down pipe and a flexpipe in between.
after that it only has a total of 5-10* max in the rest of the exhaust.

i DO NOT recommend any muffler shope that doens hace a mandrel bender!!!
press bends are super garbage, and a waste of good pipe!

 

That pic looks so much like the Pace-setter exhaust system.

 

I was looking into doing my own exhaust aswell, but ended up buying a turbo back rev-ii set up, best choice
