Icon5 True Duals, need to restore back pressure.

Hey,

I'm new to the forum. Just purchased a 94 Mazda B4000 (Ranger), and I Inherited a few problems. It's a 4.0L and it has true duals, no cats, with a 40 series on it.
The truck seems sluggish to say the least, and I'm thinking it needs back pressure. I have the stock intake with a K&N filter, I'm assuming that is adequate for the air in.
It sounds great and the tips look great. The Installation looks fantastic (very clean).
I'd rather not cut the exhaust up if I don't have to but...

Any Ideas? i was thinking some sort of tip or pipe insert?

supertrapp makes slip-on mufflers for trucks

they have adjustable baffles ( add or remove ) to attain the proper back pressure

just google it

I'll post some pics tomorrow, left my data cord at work. I checked out the Superstrapp slip ons, trying not to replace my mufflers. I noticed they had a disc only attachment. the 4" would be appropriate, I guess i would remove the tips on it now, attach them to the 2.5" pipe and find a larger tip to slide over them for aesthetics?

If you can't tell, I'm trying to be cost effective, and a solution that would preserve the current exhaust system and boost the back pressure is the most agreeable solution. This looks like it'll run me about 300. A little much for me at the moment considering other things I need to take care of on the truck, but something to consider.

If you have true dials out the back you should be able to save the back half of the exhaust and put in a single in dual out muffler and convert the front half back to single
pipe

^^^in theory. It depens on how well the system is made, but most likely this will not work.

basically ,, you just add or remove discs to increase or decrease back pressure

a lot of motorcyclists use them to replace their factory mufflers

they work very well

when i had my ninja zx6,, i should have used them instead of the other crappy 4in1 system that i ended up using

You don't understand exhaust principles if you think you "need to restore back pressure" - your problem is the exhaust pulses are slowing down, nothing to do with backpressure.

I Had a Mitsubishi Mighty Max in High School, I thought i was cool , and being rediculous... I threw corvette side pipes on it. It went from a great running mini truck to a sluggish lump of metal. A four cylinder with dual exhaust. I was rediculous. To fix the problem. and keep my "awesome" look, I found some oil filter nutz about three inches in diameter, and mounted them in the tips. Help the issue, but sounded like a fart machine. Finally wised up and threw a cherry bomb on it. I guess what I'm saying is I know it is important it extreme Measures, is it the problem here, maybe. Is it worth screwing up the current exhaust, i dunno, brought some pics tonight. lemme upload them.

BTW, I was told these were 40 series, Some one also said they sounded like 50's , so I really don't know.
And when I say "clean" I mean the welds are solid and the pipe was run/bent soundly.
What do you guys think? Should I just deal with it. It does sound good.

thats because it is most likely aluminized steel pipe, not actually aluminum, that doesn't rust nearly as bad as traditional steel pipe.

Cidepipes,
You should have leaned from the Mitsubishi, large pipe slow velocity.
What has happened is just what Jp7 stated, the exhaust was opened up, Mufflers, no Cats and probably larger ID Pipes not to mention the duals, when combined will reduce volumetric efficiency, unless there is a corresponding increase in the engine intake and performance.

Thinking on it maybe replace just the tail pipes; add a reducer and smaller ID tail pipes, this might increase the back-pressure some.
