I was asking the same question as Im interested if it works to sort the fuelling when performing a catless/flapless header swap.
Ordered the Smart unit for my '21 Scrambler a couple days ago from PCC, just shipped from the UK. I'll report back once I get it installed.I was asking the same question as Im interested if it works to sort the fuelling when performing a catless/flapless header swap.
I have the UG stainless headers/flapless/stock dual mufflers and I absolutely love the sound. I'm well past my straight piped loud as possible days and I really think the sound with stock mufflers and a catless/flapless setup is perfect. Only time I ever think it's 'loud' is on cold start - seems to run high idle for ~20 seconds or so vs the ~10s it did with the flapper and is much louder without it. Once the idle drops it really is perfect.I bit the bullet and also ordered an RB-Smart from PCC on Tues, I want something reversible if needed rather than a full remap. I have the feeling that the UG header will be too loud and I’ll swap back but at least the Smart should still be useful to bring the AFR richer.
Bummer man, makes sense why they just wanted them back instead of replacing them then.For those of us wanting a bit more power and ability to change headers, intake, muffler, etc, what other options do we have? Brentune? anything else?
That was exactly my thought process too. For $900 I want something illegally good . The guy kept trying to sell the CARB certification as a good thing... like dude my cat 'fell off' when I got it, who cares about an approved EO number.Yeah that makes sense to me too. I'd be willing to guess that CARB is nearly a strict as Euro 5. I would be interested to know if Brentune can do and "off-road" or "race-only" tune for those of us not in Cali. For the cost it would have to be a pretty significant change in my mind.
