No, You won't get back fire if you go full catless.

Go full race build, WOT throttle, suddenly let off the gas pedal you should get backfire.

Personally, its ricy.

I get backfire with my HKS and AA dps. It was louder with my Vanguard.

My old 2000 Cobra R backfired. It was not "ricey."

Back fire is not ricey, it's bad ass! I back fired when I was running only one muffler (instead of two) and no cats.

Why was I running one muffler? I purchased Vanguard, and the vendor sent me two passenger side mufflers instead of one passenger and one driver side. I didn't notice the mix up until the installation was almost over.

+1 backfire is awesome, especially when your window is down and a fully catless 335i slams 3rd gear right next to you....Ask me how i know

It backfires a lot when fully catless and meth. NLS helps a lot.

But even when meth is on at concentrations higher than 60-40 it backfires when letting off the throttle at high rpm

Damn, I'm trying to get a video but nobody wants to help me

It's not backfire you're looking for. It's afterfire.

If you are actually having backfire that is very very bad. Afterfire is the popping in the exhaust system.

I get a nice backfire as well with my AR Dps and HKS exhaust too. When under load then decelerate is when I get it. I like it, I like it a lot. LOL

Run super rich, add some meth (not recommended)

Mine pops and I have a stock exhaust. My last car used to shoot a 2-3 foot blue flame.

It was running a little rich when it shot those flames. After I tweaked the tune a bit more it would only do it in 4th gear.

The bigger flames were actually out of 1st going into 2nd mainly because I fed about 5% extra fuel in the lower gears due to wheel spin.

I have a stock catback as well and get plenty of burbles and pops when I let off the throttle...from what I've noticed the 6MT sounds a lot better stock catback than the auto counterparts..

I feel like I don't even need to upgrade the exhaust in this car..it sounds amazing as it is and has plenty of noises on and off the throttle to keep me on the edge of my seat..For my 6MT if I ever got a catback it would just be for the hell of it...to be honest it quite unnecessary..but getting rid of secondary cats is always a nice thing for those looking to go that route!

HKS BOV? *Edit: I just realized you meant HKS exhaust*

I was backfiring all the time with VRSF CLDP's and VRSF V2 exhaust on 93 octane. I just WOT and let off the gas pedal. It's awesome when I have the top down on my E93
