There were many reasons for the change of the site software, the biggest was security. The age of the old software also meant no server updates for certain programs. There are many benefits to the new software, one of the biggest is the mobile functionality. Ill fix up some stuff in the coming days, we'll also try to get some of the old addons back or the data imported back into the site like the garage. To create a thread or to reply with a post is basically the same as it was in the prior software. The default style of the site is light colored, but i temporarily added a darker colored style, to change you can find a link at the bottom of the site.
2013 RTL Exhaust - what's the angle between the muffler & the cat?
- Thread starter jcoats1

I thought the 2013 & on ST's and the 2013 RT's had the same exhaust systems - altho maybe that's just here in Oz?? :dontknow: After all, we do only get the RT mufflers on all the F3's?!? :sour:
Either way, I don't quite understand what 'short pipe' you are referring to - as far as I can see there is no 'short pipe' between the cat converter or eliminator & the muffler - at least not an OE Muffler - see the pic below! Come to that, there's no angle between those pipes either - the entry pipe for the muffler bolts straight onto the end of the cat convertor or eliminator in what is pretty much a straight line... see the pic!
The cat eliminator is the 2 pipes in the middle distance that join into one, and its inlet & out let pipes are identical to those on a stock cat converter; the OE Muffler is bolted via the joint shown directly onto the cat eliminator - and that bit in the top right foreground IS the beginning of the OE Muffler, which is all one piece (plus some trim bits.... 
)
So like I said, as far as I can see there is no 'short pipe' between them, and neither is there any angle between the muffler & converter - maybe that's something specific to RLS Exhausts &/or their style of slip-on muffler?? Have you contacted RLS about it?? That'd probably be the best source of info - there's a link to them down towards the bottom of the list of sponsors on the Home page here. :thumbup:

Still not quite getting exactly what it is you are on about/want to know?? :dontknow:
The OE Muffler is (effectively) a one piece unit from where the flange on the engine side (Right in the pic) bolts up to the cat/eliminator - see the pic below. (With toe end of foot included in the pic - simply to provide some size/scale of course! :banghead: )
Once taken off the Spyder, all that's been removed from that OE Muffler (in that pic) are the trim pieces/heat guards.... altho for the eagle-eyed out there, you might be able to also see that 'outer muffler box' itself has lost its end, cos it's been gutted - ie, all the internals of the muffler itself are gone, along with that final trim & the under-lying 'end cap' (which is normally welded on but in this case, has been cut off, as seen in the pic
) that normally holds the two little outlet pipes which are generally the only way exhaust gases can escape. :thumbup:Attachments

In other words, "j", you can't just put on any old after market muffler. The cat delete pipe, if proper fabricated, points outward and the correct muffler for your model Spyder will point inward. The two flanges will meet up. There is no standard short pipe between them - never was. When trying to attached your new muffler, it helps to keep the mounting bolt loose until you get the flanges together. Otherwise, try a custom exhaust shop and see if they can make what you need or try a different muffler.
when the 2013 was but 1 or 2 years old, the aftermarket sold a straight muffler with the correct angled pipe in between muffler and Cat or Cat delete (same angle) Most aftermarket suppliers I talked to either never saw a 998 engine in a Spyder.... or the cost to make ONE was too expensive!
Besides, it is more satisfying to make it yourself!!
