Bought a Midpipe
Ordered a midpipe earlier today. Looking forward to getting it, and I'm definitely anxious to here it. I just hope it's not too loud. I've heard it on NA setups before in videos, but we'll see how it sounds with this set up. JW, could a bad cat cause a rough idle?? I know it's typical problems of the E-manage to cause this, but I'm wondering if the cat is bad if it could be related to that as well. I would think not b/c it's not like much fuel or anything is being added at idle, since my idle afr is between 13.8 and 14.5 ususally, with lean spikes every now and then. Any input helps.

You have a big chunk of metal between the engine & the exhaust. Not sure on the B&B exhaust, but on the Borla & Greddy, an addition of the midpipe made it really, really loud.
Though get ready for the CEL from the O2 sensor going haywire.

I tried my single outlet exaust recently. It was WAYYYY to loud with my NA set up, even with the OE cat. On the turbo, it sounded great! Loudish, but great. The only reason I took it back off was that I have a backfire issue that I am working on (I think it is the BOV 'cause when I disconnected it, the backfires went away. That is postburn for you quitar.)
It was lots of fun driving around, then letting off the gas and POW-POW-POW-POW-POW-POW. All godfather like and all. Definite cop-magnet (sorry farva). However, NA the exhaust was so loud it made every plastic piece in my car buzz. Sounded like I was being attacked by hornets.
So yeah. Turbo makes things LOTS quieter.

it works a little better when you elude, rather than state.

Haha, I was gonna say I bet so when it' sitting in the garage! Hehe, don't worry Carbon, I'm not a cop. I just got the name from Super Troopers. Farva was a tool and he was funny. I'm getting the interceptor too, so backfires will go away in 2 or 3 weeks. But, until then, I let off partial throttle and it's like u said, straight up Godfather.

i drove a catless rx8 for 1500 miles with no check engine light. if the epa knew how "loose" mazda was with the catalyst efficiency monitor, they'd probably shut them down.

kinda depends on what driving type it is for some things. 1500 miles is no excuse for the CEL not to turn on, but if you're doing very short trips around town, i could see it not running the monitor. i forget the exact conditions in which that particular monitor runs though. it's been a while since the obd2 class.
