no question you want them on a 45 degree angle pointing down...but

One friend says its been proven on dynos that pointing the axel dumps 45 degrees inwards makes more horsepower.

The other says you point them outwards...what kind of idiot would point them inwards?!

So which is it friends, which way should you point axel dumps.

 

there is no way it would make more power,, your friend is imagining a crossover effect and b.s'in you,, (ask for the dyno data)

i have mine straight down for the ground pound/ street sweeper effect

most people put em outwards for tire smoke, and how loud it is when you pass someone

 

i wouldnt run them straight down because i hear you get an awful drone while cruising, this is actually going to be on my yukon, no cats and two 14" magnaflow oval bodies. Almost scared if i point them out theyll be too loud.

 

Mine was down. Untill i had to go to emissions. I had to put on a temporary tail pipe. Then cut it off just before the axle, didnt get around to putting a turn down back one.

 

people that complain about drone are babies, i want to hear my motor ALL THE TIME

 

that has nothing to do with anything, im going to hear the motor regardless of which way the dumps point.

however i do know the cruise i did in my camaro with open LT headers the drone they made when just cruising at 2500 was unbearable, im trying to stay away from that.

 

You can either have them down or 45 outwards. That is the way it has been done for many a years now between Bel Airs and galaxies with glass packs and other straight mufflers. Your the man Pennocks91ws6!! I would definitely want to hear your 383 all the time. But yess if you want to reduce your highway drone angle them out. My brother has 45 angle glasspacks with no drone, and my friend has a 1970 buick 455 with 45 angle tip round flowmasters and that thing shakes your chest. Just point them at 45 degrees and you will have good thump without resonance in the floor. Although I like resonance shaking the car. I'm a drag fan for sound.

 

ya ive decided on pointing them out

This is my DD that i drive 30 minutes to and from work on the highway every day, a ground pounder is nto what i need

 

Weld the left one to the right one for the ultimate torque gain
