    Upgraded sound system for Gen.4 SHOs?

    Thanks, guys! I do see a grille above the head-unit but I thought it was just decorative. My car is at the muffler shop now so I can’t listen or take a photo.

    Wow! Excellent post, 802! So such a wrap would benefit the PTU, and likely performance, if just applied to the downpipe?

    WHAT'S THE MAX???

    Wow! How in the heck are you getting 546 pound-feet of torque? That's f'ing amazing! What do you think is the single largest contributor to the performance-boost other than the E30-tune and fuel?

    Sorry, I confused headers with downpipes: I meant this $2,000 header-wrap that I saw posted here:

    Three bar map sensor.

    I keep reading about people here upgrading their 2-bar MAPs for the 3-bar MAP for the intake. Is this something all SHOs will benefit from (e.g., 2019 SHO PP)? I plan to get the SCT Livewire TS+ and an AO-tune for California gas (91-octane).

    Thanks, guys! SCT Livewire TS+ Performance Programmer ($599) it is! Pretty fancy looking—this costs as much as my original SCT Pro Tuner I bought 20 years ago. Do you all keep it plugged in all the time? I currently have a Verizon Hum WiFi hotspot, permanently plugged into my OBD-port. I suppose...

    Upgraded sound system for Gen.4 SHOs?

    Damnit! Can't find my build-sheet. Here's a photo of my "Sony" system. Yes, there are speakers in the 'A' pillar. Does this mean I have the 12-speaker system? Hmmm . . . nope! It appears that I only have a single speaker in the rear-deck. So without pulling any headliners, I count just seven...

    name brand catless downpipe Vs. local shop catless downpipe

    That is disappointing. I wonder if the $2,000 downpipe-wrap posted in the, "What did you do to your SHO today?" thread produces any quantitative increase in performance? (Especially in an unmodified SHO.)

    Helmholtz resonators: Which one(s) and where do you install? [2019 SHO PP + MRT]

    Another option, which is what another shop did on my Marauder, was to simply drill-out the CAT. After drilling, the Marauder passed smog multiple times (surprisingly), and never threw any codes. Also, since the SHO's lacks any sensors, I may have them do that if it doesn't add too much to the...

    Helmholtz resonators: Which one(s) and where do you install? [2019 SHO PP + MRT]

    tl;dr: keeping factory-resonator. Took my SHO and MRTs to the muffler shop today and got a look under the car (doh! totally forgot to take a picture!). The third-CAT is really small, up near the front. The factory-resonator, to the rear. The MRTs I received don't exactly fit: 1. Shop needs to...

    Helmholtz resonators: Which one(s) and where do you install? [2019 SHO PP + MRT]

    Hmmm . . . now wondering if I can get away with deleting the third-CAT (and replacing it with the X-pipe), and still pass inspection. How tight are things under there? Is there room enough for both?

    Helmholtz resonators: Which one(s) and where do you install? [2019 SHO PP + MRT]

    Thanks, kryptto! A quick Google-survey revealed a lot of "No!" replies on installing X-pipes on twin-turbos; citing the application is only meant for N/A-engines. Virtually all reported that an X-pipe will notably attenuate exhaust-sound. Then I stumbled on this interesting post on a Porche 996...

    Upgraded sound system for Gen.4 SHOs?

    Thanks! What is the "FPIS?" My GF's Fusion SE has a 390-Watt amp?

    Upgraded sound system for Gen.4 SHOs?

    Thanks for al the detailed info!!! Wait—are you saying the non-12-speaker system is not a Sony-branded system? My head-unit says "Sony" on it, but I didn't see the 12-speaker system listed on the build-sheet so I assumed I had the non-12-speaker system (whatever that is).

    So what did you do to your SHO today!?

    Wow—these look sweet! I have a 2019 SHO PP, so I assume I would order the same package. Can't decide on the color!!! I'm thinking . . . racing-red, but the dark-metallic blue sure looks nice, too (maybe even the green!).

    Helmholtz resonators: Which one(s) and where do you install? [2019 SHO PP + MRT]

    X-pipe: Yea or ney? Going back and forth on whether or not to add an X-pipe. Still looking for 2.5" X-pipes but unsure which ones will fit. I also recall someone on the Marauder forum claiming they lost power after installing their X-pipe (4.6L DOHC V8). I'm mainly installing it as a presumed...

    Wow—that's great news! Can't wait to get my AO-tune, then. Will wait until my exhaust is installed. Which tuner should I buy?

    Cool! Wasn't sure what the exact ratio was. You would think with a population of over 10 million in Los Angeles County, E85 would be more prevalent. Closest E85 station is in West L.A., about 40 minutes away in traffic. Oh well, at least I know I can get some octane-boosted performance if I...

    Is GH my only option for an AO-tune? I live in California and we're stuck with 91-octane gas. Are custom tunes even worth it with 91-octane? I had the SCT guys tune my Marauder in the early-2000s (32-valve DOHC 4.6L). They had to dial the timing back three times to eliminate the pre-ignition.

    Sounds great! Looking forward to mine.
