Thats another reason im putting my magnaflow cats back, the smell. It was fun at first but now its just annoying at every light with the windows down. Or in traffic ugh
Zero issues with my JBA hi flow cats..which are ceramic. Also JBA LT's...+ small roush M90 blower, twin 62mm TB..and 94 tune.
They did some exhaustive tests in the old 5.0 mag, and the difference between hi flow cats...and no cats was essentially zero. 1-2 hp in favor of high flow cats at a narrow rpm range.... then 1-2 hp difference in favor of no cats at a different / narrow rpm range.
With the huge increase in volume with my exhaust setup, the increase was attributed to the high flow cats (or no cats) and not the LT's. FRS-500 mufflers were installed years before the LT's and hi flow cats install. The only fix was either replace the SS FRS-500 mufflers with oem muffler's.... or weld in a pair of SS pypes M80's.
High flow cats work cuz they are bigger diameter than oem.... more parallel paths. But everything gets louder too. The exhaust just reeks on any car I have seen with no cats.

In fact the short time I did have the MBRP's on with the Magnaflows my wife asked why my car was so quiet
I'll vouch for the exhaust smell, wicked bad fumes when I start my car in the garage.
Do you have a A/F gauge ?Yeah I told Lito I think the tune was way rich because the smell was like it was drowning in fuel. He said no that was pretty normal without cats. I don't waste any time getting my car out of the garage when I start it.

I have AHR hi flow cats and also smells rich but according to my gauge is right where it should be
I don't, but he was right. It was more smell than anything, I mean there is no black smoke (real rich) or anything. I get clean plug readings and even my fuel economy (if you can say that about a modded Mustang) isn't much off of stock.
I wouldn't hesitate in asking them if they valued their customers like they used to back in the day. Problem is every time I would call in to ask questions about my tune, a certain person by the name of Doug would always talk down at me as though I was wasting his valuable time and couldn't wait to get off the phone line. Since then, I've been very hesitant when it comes to contacting Brenspeed about anything. At any rate, I don't care how good of a tuner Brenspeed happens to be, as none of that matters if they're unable to provide excellent customer service.ask em.
