Question for the catless...Does your exhaust stink?

In my experience from turbo rotary motors to all motor ls1s, to inline 6 M3 motors. Once you remove the cats the performance/power increase is always accompanied by a stinky exhaust. Obviously I won't be sniffing my tailpipe or hanging out behind my truck while soaking up the fumes. But in some of my previous cars the smell was so strong you couldn't go 5 miles to the store without smelling like you took a bath in exhaust fumes.

I've been searching but haven't seen any real complaints with the titans. I'm going to be purchasing some headers and B pipes in the very near future and I'm trying to decide if I should get the catted or resonated b pipes. Currently the truck is stock with a Borla muffler. I'm not really looking for anymore noise/volume but rather this is preventative maintenance for the headers however, the performance increase is also welcome of course.::angel::

Anyone have any feedback?

Yes any truck with the cats removed will have the raw exhaust smell. My 05 smells like a 72 Chevy just runs a lot better. The cats I use flow very well and there is not a lot of power loss at all with them. I never have dyno tested but I would say no more than 5hp or so between catted and catless.

Aah... I love the smell of no cats in the morning!



Any interest in selling your Reso B-Pipes? :thumbsup:

Let me re-phrase that...5hp difference in the high flow cats Cajun uses over going cat-less. Cajun uses 200cell metallic substrate cats and stock is 600 cell count, quite a big difference there.
