Ive a 3VZE and may be getting a set of Ceramic Coated Doug Thorley Headers. Has any one that's running these headers had any issues with them? Specifically them hanging too low....im baggin my truck in the future.

Pros and Cons?

 

I had set on my 4runner and yes they hang lower then ya like

I had to mod mine so it would work with my sas so the exhaust would not hit the drive shaft


stock


modded



all I had to do was was cut up the the pipe to tuck it up higher



what I did was cut 1 inc off the passenger side coletor


then cut about 8 inc's or s off the y pipe on the passger side


then after cutting some pipe off re welded this back on so it could slip over the collector



this si what the y piped looked like all welded up


and here is the why pipe collector





hope this help but yes chopping will have to be doen if you plan to lower it

since it really made for a IFS-4x4

 

Yeah thats what I figured.....cant thank you enough for the pictures...thats really going to help me out.

Ive also read that these wont fit on a 2wd pickup because of the torsion bar on the passenger side. Seems like I read a thread somewhere of somebody clearancing the torsion bar to make it fit but I cant find the thread now.

 

thinking about it it just might clear reason why is they hang to low so it hits the bars

the way I did it will fit with torsion bar since ti is sucked up so much

 

That makes complete sense...ill get up under my truck this afternoon and figure out how to run that S pipe. Again, thank you for the pictures!

 

Do you have any more pics of your headers (before and after install)? Im about to try and tackle this and Im just looking for a shot to the arm lol. Ive done my fair share of reading and just want to get it right.

One thing that I cant decide on is the pair and egr...keep or delete. What do you think?

 

I got rid of mine since I did not care about tree's

you can make power but you will loose gas economy from getting rid of the egr. the pair valve just for smog to help the cat work if you don't have a cat ya don't need the pair valve

that really is the only thing to think about



as for me I just got rid of it all

 

I have a cat and need all the mpgs I can get so it looks like ill be keeping both.

 

Does anybody have any tips/tricks that I need to know before starting this install? Anything else I need other than what DT sent in their kit? Thanks in advance guys!

 

remember if the egr is leaking then ya loose alot of power and milages goes to crap as well just so you know

 

Gotcha....ill make sure that everything snugs down nice and tight. Anything else?

 

nothing to do whith snug its the vavles that fails then just dump's exhuast into you intake all the time

 

NashMan....you dont by any chance have the part numbers for the starter heat shield and other wraps you used for your header install do you?

 

just dei wrap really worked for me

just check out there web site

 

Ok ill do that for sure.....thanks again!

 

When you removed the EGR...what did you use to cap the headers? My Thorleys did not come with caps in case I dont run my egr....which im not going to.

 

parts store easy to find

 

Preciate it!

 

if i remmber right any an fitting cap will work think it was -10 or -8

 

Good Deal! Thanks again for the help Nash!
