4.0 exhaust question
Leo,
I'm not saying I added big numbers or even added any numbers. What I am saying is that it doesn't make sense that gibson dynoed a ranger with the same set-up and gained hp and tq. Then flowmaster outflows it and gets worse? just doesn't make sense. Then the magnaflow flows even more than a flowmaster and gets more? Something just doesn't make sense. And the times were stop watch. Floor it and click it at the same time. Hits 60 and you click it again. I did it 4 times and got the average. And the Ram is a 96 5.9L V-8. Regular cab 4x2.
Something strange as well. This is going to sound weird but when I sit in front of my girlfriends house waiting for her I let go of the brake and see how fast (if any) the truck will idle up the slope and at what rpms. I found that pre-flowmaster it needed to be at 900 rpm to move. Now at dead idle (around 700) with the flow it goes up. Strange to me. (I got this idea from my dad when he idled with his f-150 pulling our boat out of the water.)
I'm not bashing anyone elses thoughts, tech data, or what not. I'm just saying what I've noticed this past week with the new exhaust.

A guy at my school dynoed his ram with a flow and gained 16 hp and 11 lb ft of torque. He has the dyno sheet of it as well.
I'd just like to see these facts instead of people insisting them from the butt dyno. I've seen flow charts showing that flowmaster will flow about twice as much over stock mufflers. Anyone have some charts/sheets to show this stuff?

Hey im new here still, i have a 03 ranger and i bought a flowmaster 40 series, 3inch inlet and 2 1/4 dual outlets...jegs said they didnt carry a smaller inlet...ive checked at 2 differant exhaust shops and neither of them would custom do my exhaust....I was going to do it myself, because im a mechanic, but i dont do exhaust...i leave that to the pro's....but they both said thier employees suck at bending and welding and they would have to charge 4-500 $ and i wouldnt be too happy with the outcome.....at least they were honest....im gonna search but does any one know a site where ican get a full cat back system?? Thanks

About 2 weeks afterwards, I picked up a flowmaster, used Dougs advice about a return style fuel system and a MAC CAI. With no juice I hit like 185. I was impressed. Some guy with a 03 xlt 4.0 had a K&N drop in filter and a magnaflo exhaust and spun 205 on the dyno I JUST rolled off of.
I figured ( at the time ) a glass pack would be better * good ole purple Thrush ) .. Like Leo said.. no backpressure, big drop in torque. The numbers were so bad I don't even remember them. I do know that ' Denali ' in his 3.slow tremor gave me a run for my money on the way home ( it was that bad ) .
I bought the muffler, twisted new pipes and spun 205-210. I honestly don't care for the ' sound ', theres better out there, but I love the power it provides. Most people think I have a 289 under the hood when I wind up to 7grand.

Rocky, keep searching. If you find all my exhaust threads you'll go nuts. I was looking into getting mine done since last fall but kept stalling because I couldn't find a good price. Then I finally found a guy really really close to my house that did everything for around 250. The final price of everything was about 280 because I ordered an original series flowmaster 40 but they didn't have them in 2.5 inlet, dual 2.25 because the online site is lagging in updates. So they sent me a 2.5 inlet dual 2.25 outlet delta series flowmaster 40 at half price (about 32 bucks) with free shipping.
So keep looking and you should be able to find someone in the area. One thing you could do is go on yahoo and click on the "local" link. Then type in "muffler" or "Exhaust" and put it to your area. See if any shops come up that do custom work or just give them a call. I think I called about 11 shops in the area. Tell them you want a price quote and then what you want.
If you buy a full cat back system it will be a lot more. And if you already have the muffler you might as well try to find someone to do it for you. Just some thoughts.
