say 1 is stock and 10 is as loud as possible.. and right now i would say with the cats and 50 series its about a 3.5. how loud would u say it would be with the lts and ory..

also what can i use to close the egr hole.

 

its going to be so loud that it'll make old ladies cry

 

one more question, since me and my bro are always competing against one another i lost to him last time, i was at his back bumper.. i was just wondering if the lts and ory tuned would put me again, incase.. u kno, we wanna throw down some green on it.

 

My headers are almost as quiet as stock at idel. Once it gets about 1600rpm they get louder than they would be with a muffler or catback. They are also lounder at WOT.

But you probably loose some sound quality also ( or at least I did) you can hear a lot more noise up front and they just dont sound as smooth as stock headers.

 

ill just add a bullet later.. ill let u guys know when i get them on sometime this week hopefully.

 

For the egr blockoff, you can buy a block off kit or just get a small piece of 3/16 or 1/4 inch flat steel, then mark your holes, drill them, then cut out where you need to.

 

thanks, i just put in the pcm that was retuned. i dont feel anything yet.. put i havent put on more than 5 miles. i told him to remove 50 percent tm and turn off abuse mode.. i tried to do a burn out and it was the same as stock.

 

LTs really can make that much of a difference even with a 50 series? Cuz I kinda wanna keep my cats.. unless I can get em deleted outta the PCM with my tune with an HP Tuners. But I will either run true dual.. maybe a 40 or straight pipe still, but will the headers really make that much of a noticeable difference?

 

longtubes should... after they are tuned..

 

The difference in longtubes is gonna be mostly felt above 3k RPMS
