Hi all, picked up my Dr. Mayhem a few weeks ago and haven't been able to ride it much due to weather.  I'm looking to get the S&S 2 into 1 Race exhaust that they offer.  Has anyone put this on yet?  I really like the look of the 1 smaller pipe vs the 2 and the added HP/Torque seems to be a bonus.  Just wanted to see if anyone had one yet, their impressions, etc...

Welcome to the forum, where are you from?

Several members here including myself have the TEC 2 into 2 but I've not heard any real life reports on the S&S version.  It's probably a nice piece of kit.  I believe it incorporates  a CAT or two.  The TEC doesn't.

Hi, thanks for the welcome! I am in Northern Indiana.  Anyone have issues with the aftermarket exhausts and check engine lights?  Link below is for the exhaust I want.  I've put on the short fly screen and have the bar end mirrors coming too.

Everyone here has the Tec Bikes Stinger 2-into-1 exhaust and seems to love it.  It's a flow-through exhaust as well and less than half the price of the S&S.  It's well built if a little rough around the edges.  I went over mine with 320 grit sandpaper and WD40 then worked my way up to 1500, then buffed it to a fine shine with Mothers aluminum polish and a power buffer.  I haven't posted any pictures yet but will soon.  Frankly, if you can afford the S&S exhaust I'd love to see what kind of results you get with it.  Welcome to the forum.

[Jack Straw]

I've not heard of any hassles with respect to check engine warnings.

You can bet if that was happening someone would be yelling about it.

Nobody is very bashful here.

Thanks!  I will check out the Tec exhaust.  Where is everyone buying this one at? I had not heard of it yet and really liked the S&S, but if I could save some cash - which it looks like I could then I'm for that.

Tec has some excellent videos on YouTube, including one on installing the Stinger.  In fact there are quite a few videos on the Stinger.

The Dr. Mayhem is far and away my favorite of the 650s style-wise, and apparently discontinued, like my Ravishing Red Interceptor.

Thanks for the info. I found them. It appears to be sold out as well.  Did you have to buy the fuel booster plug as well? 

[Blazes Boylan]

Watch the Tec Bikes video on the 2-into-1 either way.  The booster plug is something entirely different and not necessary to get the most from the Stinger, according to Tec Bikes anyway.  I'm not installing a booster plug because I plan to install a Power Commander or PoserTronic eventually.  There's at least one thread here debating the pros and cons of the booster plug.  It would be worth your while to do a search and read what's there.

[Jack Straw]

Blazes is right about the Booster Plug.  It's more of a subtle refinement in throttle response not a power aid.  I have one, it's a good thing but not a day and night difference maker IMHO.

BTW there's good stuff at Hitchcocks.  They're a sponsor of our forum and a first rate place to find good parts and knowledge.

Just search "TEC Stinger Exhaust for Royal Enfield 650".  I put this on my '21 not for noise or power but for a drop of 27# of unneeded weight.  I'm rather (ahem!) elderly and weigh 134# (61 kilos) and the standard RE-650's weigjt  is right at the end of my comfort zone.  I clearly notice the 27# weight reduction and I also fitted 1" shorter shock absorbers.  As other have said before me, Welcome to our forum.  There's a wealth of information here.

There are two  main differences in asthetics that favour the Tec exhaust over the S&S are 1. No lumpy CAT in the headers. 2. The left hand header on S&S passes in front of the frame down tubes and the Tec passes behind.
I cannot find any pictures of the S&S exhaust fitted showing the l/h pipe. I wonder why?

[NVDucati]

Don't know much about these as regards availability, price, etc.

I do like their approach to where they route the cross-over in the middle of the run.

[glhboy]

Thanks everyone for the responses and feedback. I'm going to call Tec today to see what lead time is on their exhaust.  I do like the less weight appeal. I'm 5'10 and weigh 150.  Any less weight on this bike will help.  I only knew about the S&S 2 into 1 because that's all I saw when doing a quick search.  I can get it for $749, but it's still a lot and plus I'd want the reusable air filter too. 

I don't like the look of the higher exhaust they use on the on/off road looking bikes...

On the S&S site there are so many warnings and disclaimers and conditions to purchasing the darned thing that it makes you wonder if they actually WANT to sell the the suckers.   Could the 2 into 1 they show actually be the exhaust version of vaporware???

Their website says,"COMING SOON".

[Jack Straw]

Yeah, sure.   Next they'll be be selling "purchase reservations".  I'll wait here.

[glhboy]

The S&S is in stock at various places. I can get one here in a couple days if wanted.  I am calling Tek today though to see what their ETA is on their pipe.

Wonder what the advantage of having a cat on the pipe vs. no cat.

[CPJS]

It makes you wonder, S&S show a race only exhaust on a road bike, why would a race bike want Cats in the exhaust.
I suppose it's just emission regs butt covering BS so they flog these exhausts to road users and keep on the right side of the law.

[Jack Straw]

It's good to hear that they can actually be purchased.  The skeptic in me wonders if they can be delivered though.  OK, I'll STFU.

That is a good looking exhaust! Having heard many Termignoni exhausts on Ducatis I'm sure it will sound as good as it looks. The lack of a heat shield right where your leg goes is a little disconcerting. Also are the pipes just changing direction or is there actually a connection between them?

I wondered the same thing. It would not surprise me if they did. If not _ it would be so easy to invisibly join them right at that spot.

Termi teased those prototype pics back in 2019, but 2 years on they still haven't got anywhere near production. Covid delays blah blah.

I’m in Wabash. Not too far. I’ve been to Goshen and Granger many times. I also had a Janus for 5 years.
