My Borla cat back with straight pipes was loud as $hit & gave off a nasty exhaust odor. I put the Hi-Flow Bassani cats back on. The exhaust note is quieter ( I like it loud ....but can live with it now) but the order is still present.
Does a rich tune create the nasty smell or is it a Cat issue or both? Just curious. Anyone have a similar situation. Thanks

Probably a combination of both..... My Bassani cats smell half way between
an off road x and the stock H with 4 cats. They pass inspection .......
The only time I notice the smell is when idling in my driveway.

I have no cats - and that adds to the rich smell. However, if you are using a canned tune(SCT, MPH, Diablo, Bamachips, etc) most of these are designed with richness in mind - to be on the safe side. A dyno tune will smooth things out, as far as A/F is concerned and will smooth out your powerband and prob give some gains across the board if your tuner knows what they're doing.

It's a custom dyno tune. Was tuned for safety & reliability. My only complaint is the smell. My wife can't stand it and hates to ride with me. (maybe that's a plus).
Hey, thanks for the replies. I wasn't sure if I was alone here.

I'm thinking about going back to a straight X Pipe.


Edit. Converted to X today. Hate the odor. Goin back and staying with Hi-Flows.
