Sulfur smell from exhaust system but it's all brand new ??
I just had a 2.5" Magnaflow Cat, 2.5" WSP b-pipe, and straight thru muffler added to my WSP Y-pipe a few weeks ago. The tone and the results have been very good for now but I notice there is a sulfur/rotten egg like smell that I lightly smell from time to time. I doubt it's the converter because I bought it brand new from redlinemax.com (thanx Angie) so I'm guessing there is possibly a leak where they didn't weld something properly before the convertor. The converter was welded to the b-pipe and a flange was welded on to the front of the converter to bolt to the y-pipe. Could it be a gasket leak or a place where they didn't weld between the flange and the converter?? And I was wondering would it be bad to have the whole system welded as one (meaning no flanges, everything one whole piece) and has anybody already done this to their exhaust?

the only time you'd smell rotten eggs is if the converter is toast. a non-converter system won't smell like rotten egss. more than likely the welding nearly the converter ruined it. happened to my converter when it was swapped from my car to the gxe.

naw, its fine. my dad wanted the cat on the gxe and i didn't want the cat so i let him have it.
i think most likely the welding heated up the stuff inside and ruined it... but i really have no clue. you might have a leak right after the cat if you smell it from under the car.

Some guy a couple months ago in super street had a ques. about that same smell and they told him it was watered down/cheapo gas that he was using, and he could either change the brand of gas or buy this bottle of scent that you empty into you gas tank and they make different scents, but i cant remeber what its called, you could probably do a search, I hope this helps

ding ding ding...there's your answer

Well I had the exhaust looked at today and the welder did a SH*TTY AZZ JOB !! It looked like he had a seizure while welding. He burnt the gasket(I don't know how) and the weld has like small holes between the cat and the front flange. Never let your brother take your car to a shop while your at work !! Anyway I'm thinking of having the y-pipe just welded to the cat and making the exhaust one whole piece. That should be okay right ?

If we did not change our exhaust out so much on our Maxima and our new Armada I would probably weld it solid.
