Not that I know of. CG precision makes a true 3.5 to 3.5 and 4 to 3.5. (Pretty sure it's 3.5")

No need for a 4". Are you making north of 900whp?

Hey mike i havent seen a bolt on option, but im gonna have the exhaust custom made for my application.

All 4" DP on the market start at 4" and tappers of to 3.5" or 3" at the end to fit the stock exhaust, since im not going to use stock exhaust i dont need the reduction in the DP
The shop that is going to do the work can make the downpipe i was just looking at options.

Thanks

Dont think there will be a 4" option
Why would companies make a DP that does not fit any exhaust that is on the market?

Your best bet is to find an exhaust company that is making a full turbo back 4" exhaust and ask them for the DP only.

There is almost zero point to an over sized exhaust other than drone and shitty exhaust tone/sound.

I personally wouldn't do it but it sounds like your only options are full custom fab turbo back setup if you want to do it.
