Heavy exhast smell

[tunerdoc]

Alright I upgraded the turbo, changed exhaust 3" no cat 15lbs boost,
ported exhaust, and O2 FMIC.
The exhaust is very strong. Could this be due to richness?
I have all caskets in place and all are tight I do not have a fuel management but I still have stock fuel pump.
Whats up.
Doc

Sorry gaskets.

It COULD be due to being rich, but I'll put my money on having no CAT.

if you can smell it near the rear end its because ya dont have a cat, i got the same problem and I hate the sound of my exhaust

Any car will smell bad without a cat. You also get a nice brown stain on your bumper above the exhaust tip.

oh great another reason for me to get a TRUE high Flow cat instead of this POS high Flow I got off EBAY! I strongly suggest not getting the chrome wannabee cat off ebay its no more than a resonator/test pipe.
