What is the best (gains) exhaust system for the 6.2 L out there?
Have an 84' 6.2 L
Stan's Headers,balance pipe,2 1/2" super turbo mufflers
2 3/4 tail pipes
That's what I have on my 84
Banks turbocharger followed by about any exhaust you want is the best!!!
My '81 has custom adapters on the manifolds allowing 2.5" pipes to leave the manifolds, turning into dual 3" pipes. A crossover pipe would also be a good idea.
How much better does the turbocharger make the 6.2 L, and how much is it?
I was looking around on the net and found a place that made exhaust systems for the 6.2 L which claims to increase HP +60 and Torque +115. Is this good compared to custom setups?
Casey, that’s it waht I also have done. Adapter on 3”., in front of the transfer case, the right line shifts at the left side, connected and as 4 ¼” in front of the rear wheel outside.
Up to the truck muffler everything is selfmade of stainless steel.
HP +60 only with a exhaust system? Forget it…
This performance is only to achieve (right word?) with a turbo-system.
60 hp gains with exhaust only? That's about the most outrageous claim I've ever heard! If you can find that info again, I'd like to see it!
Most performance exhaust systems for any vehicle or any engine rarely add more than a few horses.
A turbocharger, however, will blow more air into the combustion chambers, really increasing the power. The only place you can order a new turbo kit for the 6.2L is from Banks. It'll run you about $1800 or so. Complete systems come up on ebay from time to time and sell for around $750 or so usually. I'm not sure on exact HP and Torque gains from a turbo, but Banks' website should have that.
A turbocharger is the single biggest improvement you can make for a diesel, but it's also one of the most expensive.
I installed a Banks on a K30 some months ago. On the test stand it pressed 195HP with 6,5 psi. However I don’t believe that the engine will bear this performance for a long time…
