Exhaust manifold leak/tick

May I see few pics from the DT headers welded to the new or old cats please? Just trying to visualize how the muffler shops handle this installation. I can't imagine the PITA factor when it comes to welding in this tight area!
Best way for them to do it is set the headers in place, put cat up to it, tack weld, then pull it back out to weld completely. Not enough room otherwise.

Sent from the drivers seat of my 05 4runner.
 
Got mine 5 days ago, cats were delayed (fedex) but got them yesterday. Dropped off at shop yesterday and going to pick up today!

Updates: the tick is gone!

What cats did you end up buying/installing? Have a link?

1. planning on that
2. from far away last night, I can see chrome. Not much I can see but here you go: headers installed - Album on Imgur
3. It's very quiet. I noticed a slight improvement in throttle response when accelerating on the highway. I will have to do a 0-60 test.
4. $800 for labor in Chicago, IL.

Hope this helps.

$800 for labor for both sides sounds amazing. What kind of shop did you use? A custom exhaust shop or a regular mechanic?

Just wanted to provide an update on the DT headers and the two Magnaflow cats.

I've had them installed for a couple months now or something like that.

These headers are AMAZING. They sound beastly when combined with my Flowmaster Super 44.

Throttle response time is much better and I have noticed a slight increase in MPG. Though it is frequently offset by my now heavy foot...

Also just had my emissions done here in WA state. Passed with flying colors.

All together it ran me about $1800. $1100 ish for the labor which seems high to me, but I'm thinking the mechanic got hung up somewhere in the process.

Anyway, still cheaper than the stealership by a few hundred.

Glad to hear you passed emissions. That would be my worry too. Id be worried about using the old cats...

I got the Magnaflow 54956 Universal High-Flow Catalytic Converter Round Spun 2.5" In/Out. Cost was $130 for two on ebay from this user: dcp_deals on eBay

Custom exhaust shop. They did the welding on the manifolds as well.
 
2005 4.7 Sport Limited with a pretty healthy tick. Been aware of it for a while but I think I am finally ready to do something about it.

Visited the dealer and got the pretty typical $1500 per side story so I have been looking at going with an aftermarket + local shop install. I have a couple of local shops with good reputations, however before I start asking for estimates I was hoping I could present what (i think) are the aftermarket options.... For a successful install it sounds like there are options from:

Doug Thorley
Dorman
Pacsetter

Does anyone have the specific part numbers for each of these or pros/cons? Been searching the forum and I found several different threads, just trying to piece them together in one place.

Thank you in advance!
 
I am anxiously waiting for manifolds to crack. The day I hear that ominous tick I'm jumping on a pair of Doug Thorley shorties.

Lucky in Nv. no visual inspection . Went with urd spec headers & o2 simulator ! Quality excellent costs a bit more but wanted a tight good fit .
 
Super bummed. Picked up a 2005 v8 and didn't notice the tick or even know about it as an issue. Def has the issue. My offroad shop RSG quoted me $3400 and my dealer Mountain States Toyota said $3800. Going to try some other toyota specialist shops now.

You have a few cheaper options in Denver for sure. I have the DT headers in a box from the previous owner (who started the thread I'm linking) but I have yet to get it done. There's just other mechanical stuff that actually affects the performance of my car that I have to take care of first before I can justify fixing something I find more of an annoyance than anything (unless there's actually a worse impact to having a tick like that?).

Let us (me) know what you get quoted, or post it in the thread there too so the rest of us know.
 
‘08 V8 Sport. Ticking started about a month ago. Had what I thought was belt squeal early spring but ignored it and it went away then the ticking began, lol. Still need to replace belt and potentially pulley but never diagnosed.

Anyhoo, I only have 64k miles on the truck so I was wondering if I might qualify for some type of emissions warranty (up to 80k)...

Going to a stealer to see what they say tomorrow. Might have to go to an Indy, which some nice guys from North NJ have recommended (thank you, [MENTION=152841]ehcanadian[/MENTION])!

Anyone have any luck with a warranty claim this late in the game?

I can't really answer your question, but I will say that with all new vehicle warranties it is usually a time period and a mileage amount, it's one or the other so after the time period runs out the mileage is irrelevant, or after the mileage is reached the time period is irrelevant, so I wouldn't expect any help from a Toyota dealer in this case.

Yeah, that’s what I expect. 8 year/80k miles. Bought my car in 2016, the year emissions warranty expired. Maybe I can try to do some convincing...otherwise Thorley headers it is!
 
Just stumbled across this thread. Anyone know if this is an issue in the 5th Gen? I've been hearing this since about 30K and am currently at 62K. Would like to have this taken care of. I believe the mileage in the warranty guide is 80,000, but I'll have to double check.

Its a common issue on the v8 not sure about the v6
 
EPA performance warranty cover the manifold/exhaust issue?

(owner of a 2003 toyota 4runner limited/V8) and i'm pretty sure i have an exaust leak/cracked manifold, however i don't smell eggs...but there is definitely a ticking when the car is in acceleration, not at idle. My question(s) to anyone is:

> Is this an issue that would be covered by the EPA's performance warranty?

> I just moved to MA, don't have a MA tag yet, and haven't done an emissions test to figure out if i fail. However, since the vehicle is over 15 years old, they won't do one anyways (per the local dealer).

> I know that in order to even get this work done for free etc., you have to fail the emissions test first.

.......anyone have any ideas, besides shelling out a ton of dough? ;)
 
Is it throwing a code causing the check engine light to be on?

I’m not sure how it works in MA, but in MD the code maters, the leak doesn’t.

The cheaper solution is to pull it off have have it welded, but some say it will only last a year or so.

I have a V6 and mine is completely broken.

No, you aren't the first.

I just ordered a set today as well but from Burtman Industries. Im really tired of the noise but dont notice the smell like some say. Im going to bolt them in directly and leve the stock y pipe and catback oem for time being. I am going with the j shaped 02 spacers from amazon. I talked to a few longtube header owners and they have had no cels with these.
