Ive been waiting for this system for a while now, it was just released in the US, no price of as yet. Its made op 2.25 inch piping. Im wondering how it would stack up against the CES since the CES has 2.5 inch piping. Does the .25 inch make that much of a difference??? Surely magnaflow would have tested theirs on a dyno. What do you guys think? is 2.5 too much for NA?

2.25 or 2 1/4 is better then 2.5inch

I thought the CES was 2.25... my bad if I am wrong...

I was always told not to go past 2.25 on a 1.8.... but that may have just been the opinion of the dude that told me...

well my car uses 2.5" piping, kinda wishing i got 2 1/4 now actually, i think the engine needs a little more backpressure to get more power and from what i know on this forum, 2.25 seems to give best results...

And yeah, i am with Azza in thinking that CES was 2.25...hmmm

I am getting a CES very soon. I thought 2.5 was a bit much, however i have read that CES researches their products in depth before production, so i am confident that it will be suitable. Anyone got a CES installed?

i tot 2.5 is a bit too much..

but the guys that have CES loved their 2.5 so it maybe alright..

lots of my frens play hondas uses 2.25 on stock motors

so far they're loving the 2.25 pippings :)

unless they got full built motor then thats a diff story

The back pressure is the muffler. So I assume that 2.5 piping allow higher flow, but restricted at the muffler to gives the back pressure. It's dyno proven, what else could go wrong.

ALL but a few corollas up here in Brisvegas have some sort of CES Racing exhaust on their car ;) Dylan, Dave and Justin also have or are getting theirs soon ;)

Lucio - CES is 2.5 and has the results ;) But I would be interested in seeing magnaflows gains and also price...and how NOISEY it could be :blink:

Its gona cost around $500 US, all stainless. Im basing that by looking at the matrix exhaust. From what it sounds the CES used a higher flow pipe 2.5 inch but a more restrictive muffler, where as the magnaflow uses a 2.25 inch with a free flowing muffler. As for noise, i think the magnaflows are pretty good from what I have heard. Can anyone back me up on that?

So if i just change the stock muffler to a aftermarket with to much flow i could get decreased power?

Higher flow mufler, such as straight through, is beneficial for those who wanted hi end power. But that's just the basic explaination. For N/A, you better off buying a hi-flow, but still is restricted to balance out increase of power across the rev zone.

Didn't you say its too loud lucio? You have axle back magnas once rite?

nah mate that was an xforce.

As long as the magnas is not straight through, it will be ok. But one thing Magnas are famous for is the fact it is loud.

^^^^ditto that :)

..plus the responsiveness has been vastly improved...

B4 i bought the CES i was a bit suss about the 2.5 inch piping as i thought that it might have been too big on a 1.8, and that the bottom end would suffer......

but since the day i got it installed...no complaints watsoever.....torque has improved noticeably if n e thing :)

ONLY drawback is mine is still a TAD loud as far as CES system goes .... most prob just the tips tho ... :unsure:

still I am one happy SESS customer :)

Guys u cant compare them jsut on size...

it depends on the pipe bend.. is it mandrel bent or press bent etc? coz that determines flow and therefore one with good flow doesnt need quite as large volume

ud be stoopid to put a press bent system on a NA car ,,,,,even a turbo car

i mean y bother?....for a lil bit more money u can get a mandrel bent system that has the best flowing characteristics....

having said that....who (nowadays) puts a press bent system on their car...unless ur really really finacially restricted...

if ur gonna do it (with n e mods for that matter) do it once and do it right !

:D

This wouldn't be a copy of the mysterious droning system that "xtigerx" has. :huh:

The one which he copied a CES system and then never posted a dyno sheet to prove his gains??? :blink:

I heard 8kw but this has NEVER been proven or any dyno sheet that I can remember being posted. :unsure:

As for the drone i have it on good authority that it's just plain and simple NASTY. :o

If we are going to quote figures then please show proof - put up or shut up. I believe this is what some of you said to me when the CES system was first posted on this forum and you wanted all the proof which i supplied and you still didn't believe? :huh:

Well here's another example is it not????? :huh:

LET'S SEE SOME PROOF OF THIS "SECRET SPEC" SYSTEM????? :ph34r:

Or is it all a load of bull?My thoughts, my opinion so please I'm happy to be proven wrong. :D

I've seen Luke's Dynos and they are real gains.

Chris's system was DAMN loud but Luke's is modified to legal specs and has no drone but still the same gain.

The system is good.

      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.

      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.
