It sounds like you have an open loop exhaust system. You will want to go to a muffler shop and have them weld in a U pipe that connects the 2 exhaust pipes together at the exit. These cars do not have enough power for a Open loop exhaust.
If it is to quit after doing this drill 8 1/16th holes in the middle of the U bend this will allow just enough exhaust to get out

 

Lol you guys just came up with 5 of the most off the wall solutions lol, I think the guy asking the question needs to do all of them to make sure his car is running at the max performance level.

And make sure that you have a wire to connect both battery terminals together because your problem may be spark knock

 

I will certainly see you all in Hell

 

I might have to try and tie both terminals together never heard of that one but last year I did the reverse polarity mod and seen a gift hp gain enough I thought about removing the turbos

 

An engineer dies and reports to the Pearly Gates.

Saint Peter checks his dossier and, not seeing his name there, accidentally sends him to Hell.

It doesn't take long before the engineer becomes rather dissatisfied with the level of comfort in Hell.

He soon begins to design and build improvements.

Shortly thereafter, Hell has air conditioning, flush toilets and escalators. Needless to say, the engineer is a pretty popular guy.

One day, God calls Satan and says with a sneer: "So, how are things in Hell?"

Satan replies: "Hey, things are going great. We've got air conditioning, flush toilets, and escalators. And there's no telling what this engineer is going to come up with next."

"What!" God exclaims: "You've got an engineer? That's a mistake, he should never have been sent to Hell. Send him to me."

"Not a chance," Satan replies: "I like having an engineer on the staff, and I'm keeping him!"

God insists: "Send him back, or I'll sue!"

Satan laughs uproariously and answers:
... "Yeah, right. And where are you going to get a lawyer?"

 

lol so you wasted all the money on those turbos for nothing?

 

For my Supercrew:

What makes more sense, a turbo kit to make 350hp (ish) or a Navigator 4v swap to make 300hp? (Since it's an auto and a 4wd, I'm not thinking rear wheel numbers, just FW)

The truble-bo would probably get better MPG but be more expensive and the extra Hp would be great if it was needed.

Are turbos any good for towing/Gas engine vehicles?

 

swap a Lightning engine in!!!!! Or the 4V

 

this

Lightning swap, my truck made 450wheel with stock longblock, manifolds, and cats.
