I'm running the 40 sires flowmaster, your more or less seen this photo 100 times by now. I was told a one way 12" baffled muffler would be the best way to to go.

 

Is yours a Alpha? Flowmaster says they don't make a system for the Alpha.

 

That doesn't look like a 'system'. Looks like a muffler with a homemade dump pipe in front of the rear axle...

 

Attempting to run 37" tires with 4.10 gears, and after all of the replies stating why that combo doesn't work effectively, he's still waiting for someone to tell him the magic cure...which there isn't. And the cure sure isn't "more power". No amount of added power will fix the skewed driveline ratio's. You could have 500hp and it will still be shifting up and down and bogging down in the powerband as a result of the 4.10's.

And the cure is definately not running it down the highway in 4 wheel high locked.

I most certainly WILL NOT cause damage to my truck by putting that 33 on it. I'm not talking about driving like an idiot with it on. I'm talking about creeping out of the woods. This is an offroad truck not a faberge egg.

Also, it's Full time 4WD not AWD

 

Dude, don't get all butthurt because I'm not going to downgrade to 35's like you suggested. You thought I would get 2500 rpms in third right? You were wrong. You suggested I might be loosing backpressure due to my exhaust which could be part of the problem. You were right.... good constructive feedback. Maybe it won't fix everything, but fine that's the jouney of owning a modable whip.

If I'm literally the first person ever to have 37's on his truck with straight exhaust, then I'll figure it out myself. If not, then please get over it and let someone on here who has a similar setup or had similar issues contribute.

Also, someone mentioned a supercharger. I've considered this (for reasons unrelated to the topic of this forum) but does anyone have a supercharged Alpha on here? It took them two years to figure out how to cram a V-8 in there and I'm not seeing a lot of spare room under the hood -- but if it's possible I think it'd be awesome.

 

Okay, like stated above, the problem is you're gearing. You can add 1000hp and you're still going to be shifting up and down like crazy. Which in result will wear on your tranny and you won't have to worry about creeping out the woods with a 32" stock tire b/c of a blow out....you won't be going anywhere b/c you blew your tranny like an idiot, b/c ya don't listen. If anything going to 35" tires would be an upgrade to your h3.

Look by the looks of it you're building a mall crawler with those 37" tires and rims you're rocking out on the H3 anyway so pretty much don't worry about anything and drive your h3 the way it is. Problem solved.

 

N/m .

 

Well, here's a thought, unless you have your speedo corrected, you are probably going significantly faster than the speed indicated which could be messing with your tranny shift points. If you haven't put a computer programmer on it, it might be worth while.

 

What makes you think that mixing a 33" and a 37" tire on the same axle is a good idea? I just want to know how far you get before the diff blows. Or the transfer case gives you problems. Its highly discouraged to run a mix of worn and new tires on this system even with them being all of the same size, take a guess what will happen when the limited slip stops slipping after trying to match a 33" tire rotation to a 37".
