So... aside from custom fabbed, there are no 3" exhaust systems available for the SHO?  😲

You mean turboback/catback?  No prefabbed that I know of.

3" downpipes you can get from Unleashed  Tuning, I think.

If tuned:  Take note of the strategy code as you return to stock (including 3 bar MAP to 2 bar MAP) -> take car in & get it serviced -> check strategy code when you get car back -> have tuner update your tune if the strategy code has changed -> reload tune -> ENJOY!

Those have been off his website for a long time now.  In fact, the DPs he sells are SW now.

I highly suggest you listen to a 2.5" straight through setup, it doesn't sound good IMHO and many others. Nothing like doing a custom exhaust and then undoing it. :)

Kinda disappointing / surprising that nothing bigger than 2.5" is readily available.  Turbo cars like to BREATHE...

Loud is no problem for me, I'm coming from an '05 SRT4 with 3" mandrel pipe from the turbo back & a Dynomax race bullet muffler where the cat used to be.  Ride before that was an '01 Lightning with Bassani headers & exhaust.

They like to breathe when they are moving air and these baby turbos aren't really moving much.....dual 2.5" pipes are moving plenty of exhaust for our turbos is say

Exactly how small? Are the turbos' specs available?

I'm coming from an SRT4 & the Skittle's turbo is pretty pretty itty bitty but it definitely benefitted from moving from a 2.5" Mopar exhaust to a 3" B&B knockoff.

The sho's Turbos are smaller I think...that's why they can make 20 psi if programmed correctly...not that we have the fuel for that anyway....also you dopar only had single exhaust..so do the math on dual 2.5" pipes ...it's a lot more than a single 3" pipe

Only smaller turbos I have seen were on motorcycle turbos lol

Garrett GT15. They are effing TINY.  So small, that for me at higher elevation they get their asses kicked when asking for above stock power out of them.

Yeah it's crazy..The first time I took my downpipes off and saw the turbine I couldn't believe that an entire bank of cylinders' exhaust exits through that hole AND passing through the restriction that is the wheel itself.

Not a whole lot though.  A single 3.5" exhaust will flow better than a dual 2.5" exhaust.  Single exhausts flow better than dual exhausts because they keep the exhaust gases hotter than a dual exhaust.  Dual exhausts expose more surface area to the atmosphere and run cooler.  Cooler air is thicker and flows less than hot air.  Same reason black cars are faster than silver and white cars. ;D

3" pipe would have about 28% reduction in area so I don't know if I would say "not a whole lot though"...I don't know that the temp of the pipe after the turbos matter much, I think you are reaching there
