There's a few ways of doing it -- like rwense and some other guys who have cutout the rear valance (the part you're calling a diffuser), and/or cutting the actual rear bumper cover along with the valance.
Trimming the valance like above won't require you to remove/relocate the charcoal canister...
Bailey Woods who's been dominating Time Attack events recently is running a B48 in an E36 M3. There's quite a few guys running the B48 for their Time Attack setup if the power goal is 500-600HP.
I went two off into the rocks when I was going too hot into Turn 11 at Laguna Seca. Splitter dipped into the rocks and the side of the car ate them up too. Yummy
A lot of it is in the tuning, flywheel weight and reportedly the rev-match option if you use it.
personally haven’t tuned my MT, but there was a slight difference in rev hang when I had a new clutch and lighter flywheel installed, but it wasn’t major. I’ve also done the CDV delete and bushing...
would those Verus pucks work with these? You might still need to drive up some wood, but atleast you wouldn't have to align the quickjacks to the female jackpoints
you lose a lot of the lower tones through the phone/PC/youtube, so just be mindful of that. I used to have the HKS exhaust and it sounded a lot more raspy online than it did in-person. In person it had a really nice low-end tone to it.
If anyone tracks their car, they're inherently accepting that it's completely possible it can be wrecked - I don't think that's lost on anyone. I don't ride anymore, and I want to continue to develop and track my Supra. Is that an issue?
dude, just talk to some local Supra owners at a weekly Cars & Coffee in your area and ask to hear/listen to their car. I get why you posted but at the end of the day, it's really difficult for us to truly quantify this stuff. We can say "this exhaust is louder than that one", but even then...
