• 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.

998cc Exhaust - can I keep the OEM Muffler with a Cat delete pipe?

I have a question about the cat delete pipe. Can I keep the OEM muffler with this pipe or do I have to change the muffler as well?
 
You sure can!! :ohyea: Some even argue that it sounds and works 'best' this way! :thumbup:

:agree: .... If you add the " Baffle " it will change a bit .... on 1330 RT I tried it with and without ..... I decided to keep the Baffle ..... IMHO the CAT delete will effect the weight and sound .... not performance .... Mike
 
Agree with Peter. Sounds magic with cat delete and stock muffler. Had Jases ECU upgrade as well.

Tip: get the cat delete pipe ceramic coated inside and outside, reduces heat by a long way.
 
Options from RLS for a 2013 rt-s sm5....
Exhaust @$325....cat bypass @425...
Any experienced opinions on the best option?
 
Tatonka, did you make a change? I'm looking into doing the same cat delete with RLS pipe. if so, how did it go and do you like it?
