I have 2 x 7" x 11" cylinder mid resonators. Quiet at idle and medium loud & very deep sounding when I give it. now I scrape so bad over driveways & ramps it's not funny, I'm talking about crunching the resi's ppl turn and look even tho my car isn't that low the resonators r. I have a straight through magnaflow rear muffler and need a middle resonator that will not sit so low due to the large diameter ( my current have been lifted too) but I'd like to keep the sound and performance the way it is. I'm told my my exhaust guy this is hard to do. Straight through everything is best for performance and enough packing in the resonators is crucial to the sound. What r u using??

this is what im using...

not sure about the dimensions but its certainly not 7'' diameter... the length its a total of 14'' this i found was the bear minimum to keep it from farting at high rpm. it only farts when the engine isn't fully warmed up (but who floors it when its not propery warmed up anyways?)

this is a generic brand, u can try the magnaflow resonators, they basically do the same thing anyways.

R these the hotdog type glasspack resi's? mine are shaped like a cylinder with a lip, it comes down alot more than urs and is the reason i scrape ( badly, with no exaggeration) I like the sound I get it's quiet but deep tough sounding I wouldn't mind it to be louder but I want to keep deepness more than anything, where did u get urs done at?

not sure what are packed inside these hot dogs but when i looked inside, the design was very much like the magnaflow ones. they allow sound baffling with no hinderance of flow whatsoever. i was looking just getting rid of the farting noise. i can control how loud it is with the varex. i further raised my car also and i've told the guy to tuck it up as much as he could. i got it done here in melbourne. any DECENT exhaust place should be able to tuck it up as much as possible. if they have tucked it up as much as possible the only other thing u have to do is raise ur car abit.

yeah but i think u can get ones with a steel mesh instead of fibreglass, but yeah for me i dnt have a varex just the straight thru s/s magnaflow rear oval muffler, its tucked up to the maximum and abit reluctant to raise the car as it is not stupid low and will look 4x4 styles lol. wondering if there are straigh thru oval resonators that will keep it deep, maybe 2 x small ones or 1x long one. the pictures attached is what i currently have installed.

I also use a 14" straight thru muffler with 2.5" in & out..is this what most sportivo owners use? I've heard alot of u use twin loop type rear muffler but when I installed one I found it caused too much back pressure and was sluggish.

u had a varex? just close the flap and it will be quiet. and that resonator(s) is/are overkill...

No not a varex muffler. Also Just wondering if a 14" rear oval muffler is what u guys would use? yeah they look abit much and are big, the thing I like about them is just the no fart sound at any rev ranges a very deep sound yet quiet. I do want it abit louder and more aggressive but would like to retain the deepness and the performance (straight thru 2.5" everything I have found is best 4 performance) maybe a 5" x14" round resonator instead of this 7" x 12" round with lip would do the trick.

u see mine on the top? its not as big as yours. the sound is nice. no fart and is tucked up quite nicely. u want sound, u have to release more back pressure. that means using a smaller hot dog but not too small as it will not do much to quell the fart noise

Maybe get 2 smaller hotdog resonators that are abit smaller profile?

i had twin hotdogs welded into a straightline pipe, not muffler, sounds fine, tucked well and had the clearance i was after.

      OK. Does any of Toyota's advertising material mention Android Auto? If so then kick up a stink, with Toyota management, about misrepresentation and false advertising, reminding them of the hefty fines. Herb

      1999 Camry Driver's door locking hatch issue

      It's possible that it could be something fouling or dirt build up, dry, or a broken mechanism, so have a look and give the mechanism some lubrication, most likely though, it'll be the actuator. I found one for a good price on Ebay, $25 delivered: Front Door Lock Actuator Right Side For Toyota Camry 1997-2001 | eBay

      Query about the correct rotors for 2006 ACV40 Camry.

      Hi, I'm looking at a set of front rotors for an ACV40 2006, 2.4L Camry. I got a good price on some RDA's at Sparesbox. However both RDA8112 and RDA7686 show as for my car and I'm wondering what the difference is and if there were changes to the rotors during the model production. So does anyone know which rotor is the correct one? Many thanks in advance.

      Android auto

      It's a simple solution though? Already laying down 60k for a RAV4, so what's another 1k on a phone to make everything work seamlessly? 👍

      Your solution is akin to suggesting that switching to a different car manufacturer would resolve the issue. However, not everyone shares the same enthusiasm for using an iPhone as you do.

      Turboed Corolla Overbuilt?

      that engine will be fine, the rods are the main thing to be concerned about. The 2860 is a decent turbo for the 1zz but in this day and age I'd go for a G25-550. The injectors might be on the small side, we run DW1000's. You need a full length injector, the shorter injectors with adaptors like ID1050x dont fit the 1zz head. You don't need an aftermarket intake manifold, if you do go down that path, avoid the CNC innovations unit, it's garbage. Do the boost control with a MAC valve and control it with the aftermarket ECU of your choice, I use Link stuff on most of my builds with the G4x Storm as the minimum. I also wire a fuel pressure sensor and oil pressure sensor to the ECU in my installs. Use a decent intercooler, the better cores (ARE, PWR, Garrett, Vibrant, Plazmaman, Hypertune) work a lot better than the chinese stuff like Aeroflow. a 450x250-300 fits fairly well with custom end tanks to route the cooler pipes through next to the radiator Don't forget about the clutch and gearbox. These days I like the Uniclutch twinplate, Above 300whp you'll want to think about upgrading the 3rd and 4th gears in the box also with the SSC (Hollinger) gear set and install an LSD of your choice. If you're going to give it a hard time, you'll also want an oil cooler. I like the HKS thermostat type sandwich plates and setrab or mocal oil coolers with -10 speedflow fittings/lines (Chinese AN fittings neck down to a lot smaller internal diameter in their bends, not great for flow) You'll also want to think about brakes, Celica or Sportivo front calipers will bolt on with sportivo discs as a starting point. To have somewhere like Tunehouse do the work you'll want to budget somewhere between 20-40K

      Camry Touring 2010 Fuel consumption 15.2L/100km. Normal?

      I did the mathematics myself regarding costs vs benefits for fuel injector cleaner. I have changed from 91ULP to 95PULP and 98PULP. Price difference can be about 13 -20 cents. Compared to 91ULP, Premium quality fuel should have a better quality additive package designed to have superior engine cleaning capabilities so the engine can perform at their best.

      "Fuel injector cleaner is a waste of money" Only if you by the cheap crap if you use LiquMolly a German Product it does work and you won't waste your Money.
