true, i actually hadnt thought of that

 

heck naw i think it actually builds a barrier so dirt wont stick to your underside and helps keep your truck warmer in the winter months. i dont ever sit around too much, here in tulsa there isn't too much traffic.

can you hear me now

 

been playin around on youtube, really liking the sound of cut-outs as well as the gibsons when the cut-outs are closed. the turbines sounded nice too. any recommendations for headers or cats?

 

pacesetter are nice and cheap. idk about the 4.7 but long tubes are the way to go for the hemi. i think a set is less than 300.00. dynamax makes a header/hi flow cat set up for our trucks but its like 1200.00

 

dont think pacesetter makes headers for the 4.7s though. least i couldnt find them anywhere

 

Ive read Gibson are the ones for 4.7s

I went from stock exhaust to a fut catback system to a single cutout (which I loved the most) and soon will be heading to full headers and duals with 2 cutouts.

But you need to make sure you can pass any inspection with a cutout on the truck

heres a great intake for the price i love mine .....

 

Again it really has to do with the placement of the pipe. I have mine dumping up and over the axel at a slight angle not straight down so no gasses are being trapped under the truck.




Also dumping it is suppose to get rid of any resonance or drone that you may be experiencing inside the cab with a louder exhaust. So really, as long as it is done right, it is the perfect exhaust setup for someone who wants a really loud exhaust but not the interior noise that comes along with it.

 

You can get long tube headers if you want to basically buy a set and have them custom made. I can shoot you a link if you are interested.

 

here is how to do it yourself

1) buy a set of stock manifold gaskets & seperate the led from the stainless discard the led pieces, the stainless pieces will be your templates for the 4.7l flanges. take these to a machine shop and get them to make you some new flanges WITHOUT AN EGR PORT you absolutly do not need an egr port and it will not cause any check engine codes . keeping a port on your right head WILL prove to be a performance robing nightmare. EITHER WAY port or no port make sure that the flange covers that hole. you can use the flanges on your shorty headers as a more cost effective option however there will obviously be some down time for your truck in that case.you can weld or have welded the egr port on the flange shut

2)buy a set of headers that are NOT tri-y or ceramic coated (bare stainless steel or steel will be the easiest to weld without needing to grind down a coating and the tri-y's are unfortunatly to complex to add/ takeaway tubing)

3)if you own a sawsall buy some milwaukie torch blades and cut the flanges off the headers completly flush, this cut will be made right through the welds,
the stainless will be very difficult to cut so use a large electric grinder with a 6" cutoff blade

4)NOW you have flanges and headers that need to be moved to mate to the holes this is a job for a machine shop . my machine shop guy told me that this took 8 hours for both headers to be alligned and welded going rates at machine shops for this work are between $75-$80 per hour they will also have to weld shut a small hole in the #1 cylinder tube right bank as this is the location of the hemi's egr again if you have a welder this is another small savings

as you saw in the video there is lots of room around the header and about 2-3" above the collectors that being said the most important detail is to keep the flange angle the same as the hemi's also order the headers for the corresponding hemi truck ( your year, cab, bed, and weather you have a 4x2 / 4x4) i used the pacesetter headers and am very happy with the results and you should be able to get it done with less then 1000 (excluding cats and y-pipe


actually here is a group buy in the works for custom 4.7 LT headers (remove the spaces)
