Smelly Exhaust

[CatlessWonder]

I have had a Dr.Gas off-road X-pipe for about 2 months now and the thing really smells. I have added MIL-eliminators and it reduced the smell some but its still really bad. For anybody who has a DR.Gas pipe, is there anyway to fit cats on it, I dont see where the heck they would go on mine. Anyways, I dont seem to have lost any power, throttle response is great, and it just screams at WOT, I enjoy going under the bridges in Atlanta, its a riot. What Im getting at is, I just wanna know if the smell is coming from the car running to rich or is it somehting more serious. Since it has gotten cold, you can see the cars exhaust and mine just billows exhuast like a smoke stack, I just hope its not a serious issue.

The noxious smell (extra cloud of smoke when cool outside - this is just condensation) is from the lack of cats. Specifically, it's the unburnt emissions.
It's the nature of the beast when running an off-road exhaust...you could always have catalytic converters welded into your existing pipe if it really bugs you that much...

I have the same problem with my 2001 GT with the Shortie header system.
Did you ever add cats to that thing?
If so, how?

you could have cats welded in....I've seen in the summit catalog that there are additives that I think you add to your fuel that make your exhaust smell like certain aromas. Might wanna check that out.
