paint94979 wroteThought it was just me but I found the MAD secondary DP fitment pretty bad assuming you're experiencing the same thing with both their primary and secondary DP.I'm ordering a set of ER catless primaries
VipTouge wroteExactly. I don't want any issues moving forward, I've already got misaligned holes and sheared off bolts. They're nice looking pieces but I don't want to risk it, fortunately ER is having a 20% off sale.Thought it was just me but I found the MAD secondary DP fitment pretty bad assuming you're experiencing the same thing with both their primary and secondary DP.
Mort443 wroteMy dealership is really cool and doesn't care one bit but most are not like that...Anyone know if dealers in the us give you shit for changing cats? I like my warranty and free oil changes etc.
Evolution Racewerks catless primaries were out of stock, just got the call that they'll be shipping my set out today or tomorrow.
The quality is solid. I’ve used them on a bunch of different cars without issues. Currently waiting for a set of my DBX707 downpipes. (from skyley).
OP - definitely want to here how it sounds without cats.
x622 wroteSounds about right.I believe these are Skyley chinese downpipes if I remember right. MAD is a dropshipper.

Me too, it should sound halfway decent.
x622 wroteI did buy a fiber insulated heat shield... I just hadn't installed it at the time of the posted pictures. I did also wrap my catless secondaries with the same material.I find it fascinating that none of these guys heatshield or ceramic coat these. It makes a MASSIVE difference in underhood temps.
I know Redstar offers a heat shield option.
paint94979 wroteExhaust wrap? I'd like to see a pic if you have the chance. Not familiar with a fiber insulated heat shield outside of exhaust wrap.I did buy a fiber insulated heat shield...

paint94979 wroteCool stuff thank you!
Anyone want to post their LCI x5m with no cats? I want to hear it:happyanim:
Had a few issues installing/reassembling. I will say this RG Sport is absolutely fantastic, their customer service is second to none.
The car is definitely louder, you can definitely hear the turbos now...
yodabro wroteIt definitely doesn't sounds badthis is mean! congrats! sounds scary!
. Now to get it tuned...
paint94979 wroteexcited and good luck!It definitely doesn't sounds bad
tune - proper custom one? Do you know a person or a shop? Or you gonna diy?
yodabro wroteHonestly I've found next to zero info regarding these S68's and their capabilities or lack thereof... I'm likely going to go with whatever tuner that can offer me two things... 1. Remote flashing and dyno tuning 2. The ability for me to flash my car back to stock with my stock file.I wonder how stable longevity-wise they will be, the extra aggressive ones. Will you be adding any additional cooling and whatever is possible, for your driveshaft and axles? I have been hearing horror stories about how anything above 760hp just rips through driveshafts, axles, and stock clutches can slip...
I'm a little skeptical with custom tuning in general for the F95/F96, I have yet to find anyone that has had their car tuned yet these tuners are claiming HP and TQ numbers, kinda weird. I know that tuners are buying DMOS files from Europe as they aren't mapping their own .bin files.
