we are using stainless marine gen 3 manifolds with 5inch tail pipes, and are running 555c.i. procharged to be 960hp. i cant find any switchable mufflers for the 5inch pipes. if anyone has any leads please post. thanks

I bought mine from livorsi 3 tears ago. Brian

crying because of what they charged?????

wouldnt blame you

No, not crying at all. I just didnt read what i wrote. sorry about the typo. Brian

were tehy 5inch? i know cmi makes em, but they are near 1500 per engine

was only kidding im no one to talk cant spell to save my life just thought it was funny, sorry

Stinger, Stellings will make you some Kick Ass exaust and will not drain a lot of power. They made twim 1300's pass under 90 decibles.

What type of setup are you referring too??? Typical stellings headers with tailpipes wetted near the tips? What kind of muffler?

Do you have any pictures of the setup, love to see them!

If i remember right they were around 3500, but that included a compressor. I like them alot, but dont like the air cylinders on them. You have to keep the shafts well lubricated so they work freely. I you go to the livorsi website theyre on there. Everything i have ever gotten from them has been good so i keep going back. Brian

Ditch the switch and go full time.
No moving parts and the new mufflers out there, work very well.
Eventually you will have to.
