Backpressure

[greenmachine2000]

well i have a y pipe id like to put on but only concern is losing backpressure, how much will it lose if any?? i got a 2 inch down pipe going to gibson single inlet, to dual outlet, i have all the pieces to complete this just have to get question answered to decide if i wanna do it, or sell it.

Idk if this sounds right but I have a 3" connecting the flange and exhaust the goes to 2 1/4" and the tips come out at 3.5"

oh crap numbers, i was never good at these things. mine goes 2 to 1 3/4 duals i think?

If you take the cats and muffler off, you'll lose most of your backpressure, which will kill your gas mileage.

hell weld it and see how it goes

[Redneck_ranger]

Bring it over here and my buddy will do it for you. He needs work and could use the money.

I got hedman headers that came with a new OEM style y-pipe. I gutted my cat and ran 3" single into a flowmaster super 44 with dual 2.5" straight out the back into 3.5" SS Silverline tips and I've had absolutely no problem with backpressure.

 

[greenmachine2000]

sweet i might get this welded up sometime next week then.
