Anyone with BBK LT's have any issues with the 02 extensions and tuning?

But I don't think I can install all of that myself, even with my dads lift. I think a shop would be needed, and that will cost more .
I don't believe the shorty headers are CARB Exempt.

I have bbk shorty headers and catless midpipe. That way I can just swap out the midpipe if I need to living in Cali and make it ok for smog. I think it pulls much harder than before. I spin up to 45 mph off idle at 750 rpm. It sounds good too, but very aggressive. There are some drive by videos on my channel.

Sorry but that's just B.S.! Shorties are definitely worth it, they offer decent gains and torque. What was the BAMA reps name, so I can make sure not to deal with that person!

Lol, wish I knew his name. Honestly, if they do make a difference, should there be a difference in the tune? I did read somewhere that someone was dataloging his car for a Steeda tune I believe and they did notice a difference and accounted for it in the new tune. Should I expect BAMA to write a modified tune even though they seem to think it is unnecessary? From what I remember, the post talked about the shorties creating the car to run leaner up at higher revs, but honestly I don't remember. And I don't think I will be able to convince BAMA to put shorties on a car and go test it out for me.. lol

Also, I run a 91 race tune, should I ask for a hybrid tune? I feel the race tune had better throttle response and power than street, so why would I want a mix of the two? I know I can always try it out and swap back, but does anyone have any input as how they actually differ real world, as in how they feel comparatively?

The ECU in the car even tuned makes adjustments on its own, so a lot of things that require no tune piggyback on it. I put the headers on and could feel the difference before I put the header tune in. Also if it is not running good or having problems you can Data log it and send it to them and they will change the tune to what the Data Log says.

Not sure where you got this from, but headers make a huge difference in the sound, both in tone and volume. Different tubing lengths, thicknesses, and shape will yield different sound, that's basic acoustics.

This may be helpful...

My wife's Mustang had Borla ATAK's on it for 4 months before we installed BBK LT's with cats. The headers made a huge sound increase, but the sound type stayed nearly the same (still sounds like the ATAK, just louder).

Wife = 2012 Mustang V6 Premium Grabber Blue BBK CAI, BBK LT w/ HFC, Borla ATAK, MPT Tune, DSS Driveshaft, 3.73 FRPP Gears, BMR LCA's | Best = 13.5 @ 105
Husband = 2010 Camaro V6 Synergy Green Edition IPF Supercharger Best = 12.5 @ 111
Closest finish @ the line = Wife by 0.0028 seconds (4.79 inches)

Yup that's exactly what was happening and that was me. I had the shorties on the car and noticed that it would run weird sometimes and run hard others. The datalogs revealed that the car was leaning out in the 2500-4000 rpm range and from 5500-7000 rpm. To stop the engine from running to lean, it would limit the throttle and not open up the throttle body all the way when I went WOT. The values for commanded throttle and actual throttle position were off at times by a decent amount.

After the tune it felt much better... in my case at least. Some say that a retune is not required... but after the retune the car performed much better and I raced a friend before the retune and was close to him and after I began to pull right as I hit the gas. I also lost throttle response that I got back and then some after the retune. I'm very pleased with the gains from the shorty headers + lethal midpipe.

The shorties are a nice upgrade, and a good way to have a full exhaust in California that can easily be swapped out to pass emissions by putting the stock midpipe on.

Either way you have 5 years I think until you need to smog the car.

Bama doesn't know what they're talking about in this case. I love them but they're incorrect. And they haven't done any testing on shorties for the 3.7L so their comments are just supposition. I can tell you that MPT definitely saw some things that needed to be changed after shorties went in and personally they are well worth it.

All I cant tell you is that Bama turned off the rear sensors on my hybrid and race tune. They told me I would have to return the tune to stock to pass emissions.
