Larger Exhaust on a D24 NA?

[RedArrow]

Thank you for the quick response. I found a seller that states the silencer he has fits a td 760. There`s one way to figure out, I plan to meet him in person to compare it to the one on the car (will be tricky). Many other websites also happen to list the very same item for the turbo 760 (6cyl gasser)and the turbodiesel d24t 760. I am not sure they used the same part but who knows? It is very hard to figure it all out. I wish it all just fit without tinkering. The car was a gasser originally so maybe it has all the places for a gasser exhaust and any unit will fit? I have no idea yet.

In the meantime I found this for good reference.

There`s no 'good piece' of the rotten d24t silencer section piping that is currently on, so I will need to see what to do with a new unit to achieve a good fit. I really do not want to get into having to weld it (that`s partly why I prefer the stock system which should be plug-and-play plus adding clamps at certain factory places.)

None of the resonator/silencer units I found show the straight section that the d24t page displays.
It looks like that the one I removed is probably an original d24t part, judging from the straight section between downpipe and silencer/resonator.

Shouldn't be too difficult. You can slide the piece up alongside the existing under the car and get a good visual on matching the length, connection locations/angles, and hanger mounts. Should be obvious. *Might* want to jack up that side of the car for easier access so bring your floor jack and stands. Bring tape measure and possible calipers as well.

Doubt that Volvo stamped different floor pans for different engine models. Don't worry about that.

RedArrow, what did you end up going with?

Anyway, I went with a resonator delete, straight pipe section welded in, as replacement front section exhaust parts are apparently NLA.

$90 out the door at a local independent muffler shop.

First impressions are that I can't really tell much of a difference in sound level or quality from stock. Thought I could newly hear a bit more low turbo whine at low speeds.

The old resonator had a good-sized hole in the side of the can where it was blasting out long wispy tails of sooty fiberglass. Snagged on the axle bolts, rear wiper blade, strewn along my path in general. Definite improvement.

The problem with most gasser (seeming) equivalents is that they are one size smaller (2" vs. 2-1/4?).

Sidenote: Bit of a change in routine for them as they have recently been mostly busy replacing catalytic converters for victims of rampant CC theft in this area.

Common everywhere now seemingly. It is an infuriating problem as the obvious root cause (to me, IMO) is the scrappers buying the stolen goods and providing a market for the thieves. They have to know, don't they? The same guy shows up over and over with cats that were obviously buzzed off in a hurry, and they are happy to buy them each time?

Apparently the vehicles that get hit hardest are pickups and SUVs since they sit higher, the easier for a thief to slide underneath with the sawzall. Thus I have heard it is often someone's business vehicle, a work truck or van, etc that they depend on for their living. Not that that's any worse than someone's commuter vehicle, unfair either way. But maybe one way to avoid it is to drive a regular car instead of a truck or SUV.

I actually just this winter bought an old mid 90s Land Rover as a 4x4 snow beater, cheap, after its PO parked it in downtown Billings and came out to discover the cats were gone. Sounded like a ski boat when I went to see it and start it up with open headers on the old Buick/Rover V8 gas hog. But felt terrible for the owners as they had obviously tried to take care of the truck and put a lot into it, and this was the last straw for them. So in some ways the cat theft was a windfall for me since it made the truck worthless ($2000 to get new Y pipe with cats from Rover dealer). Had my local muffler place do some straight pipes in place of the cats since for my purposes this works OK and no emissions testing here of course. It is a miserable reality for folks to face this though. Perhaps good business for the muffler shops.



ngoma looks like good work done on yours for $90! My wagon has the same setup. Straight pipe where the front muffler/resonator was, done before I got the car so always been that way. I have never been able to tell that it sounds any different from one with the full factory exhaust.

Actually here most recently the CC thefts have slowed down. Entire car theft has soared. Kia/Hyundai every day (evidently there is a new recall to remedy a "deficiency" in their anti-theft features), Subarus are also popular theft victims, as are '90s Hondas. MOST recently, Ford trucks and vans are most popular, stolen and used to bash into storefronts for further burglary.

Often, when found, these stolen vehicles are trashed with needles, misc. mail, many are deemed hazmat totals, soaked in meth manufacture residues.

Yeah, indeed on all that. In fact just in my own personal immediate experience, two relatives of mine in the Puget Sound area had cars stolen that way in the last few months. Both of them older Subarus and both with manual transmissions, which really surprised me. I had always heard the saying that the best antitheft system available is a manual transmission, especially in the modern age where some single digit % of drivers on the road know how to operate one. But apparently the crooks have figured out how to get around that.

First was a ~2002 WRX that had been owned by a relative up Avalon Way in W Seattle on the north end. Car he had had forever and competed with in rally events all over WA, OR, BC, so attached to it. Had upgraded engine and differentials, suspension, etc..... Stolen and then found a few days later down on W Marginal somewhere full of drug gear and was totaled as a biohazard, just like you say. He could have bought it back as a salvage and probably replaced the interior and revived it, but was sad enough about it that he decided to give up and move on.

Second was a ~1999 Outback owned by my brother-in-law in Bellingham. Disappeared overnight from the parking lot in his apartment complex right under bright lights! Found a few days later nearby in Fairhaven completely full of computers, cell phones, tools, AND lots of keys to other vehicles. Fortunately minimal damage to the car itself and he got it back.... And installed a secret fuel pump disable switch in a hard to find location.

Also had a friend get a nice motorcycle stolen in W Seattle in the past year, don't think that one was ever found. Plus as I recall you have had some bike thefts.

Part of what is most unfair about that trend is apparently the thieves have realized older vehicles are easiest to steal, plus they are usually not stealing for the car's value but rather simply as transportation to commit other crimes.... So their targets are often 20yo-plus Subarus and Hondas and the like. Thus the victims are less likely to be folks of means with newer vehicles that are probably covered by comprehensive insurance; instead more likely someone driving an older car with no theft insurance and not with enough cash lying around to easily absorb the loss of a major asset, plus their transportation to work, etc. This was certainly true in one of the two cases above.

It's a mean world eh?

Sorry for the thread hijack.
