Magnaflow is just awesome, just order it you won't regret it. Such a good system. Sounds amazing. And you have options with mid popes and mufflers with the kit. Love it.
Gonna be blunt here, the work looks about as nice as a plumbers azz. I also have full body ppf+ceramic, xpel. Install was of flawless quality and everything is still holding up perfectly one year later. Make them fix this or demand a refund, amateur work. Wouldn't have taken it home like this...
I'm quite sure b58 is supposed to run at 230-232 degrees as nominal. 235 isn't too crazy. I have csf heat exchanger and pushing 23 psi on jb4 with E40, no heat problems. I think you're fine but you could always get a csf cooling package
IMO they are definitely planning a hybrid Supra. It would be stupid of them not to. The sheer performance per dollar with the decade+ of creating and innovating hybrids is clear. They could take Mazdas inline 6, twin turbo and still have hybrid and AWD. If they don't do it it's because they hate...
Putting the box cover should also help keep the air slightly cooler if you watch IATS. Without the box it's truly a hot-air intake. Stock box might actually be superior. Also removing the engine cover helps as well. Imo it looks pretty cool without the box. And it's super loud.
I've had my HK box Set up all summer. (FBO car)Can still hear it pretty decent inside and especially outside even with Magnaflow exhaust with race baffle on active flap side wide open.
It definitely decreased my iats but I also have a csf upgraded exchanger.
Side note Nominal IATs witb this car...
I've never noticed this issue while driving. I have noticed it during start up. Sometimes it won't Rev when depressed and will just die on cold start. Snorkel snorkel dead kinda thing like so many have experienced.
No recall done yet.
FBO car, I guess I haven't noticed it since leaving stock...
Very high chance it's the same 6 spd from the 440i etc. It's a decent tranny. I'd say expect the same journey as Kern from YouTube if modding the manual. Definitely gonna need some upgrades to make the big Boi power. The 8spd makes quite a lot without even a Pure upgrade. Well over 500/500 and...
Before high flow cat, made about 5psi at 3k rpm, after car makes 18psi at 2900 rpm. AA catted. I have logs showing this. Pretty dang good increase and no cel.
