Who's running stage 2 with a 3" decat/downpipe and the oem catback?

[burt2000]

There seems to be conflicting views on this and wether or not you can run stage 2 software with a decat dp mated to the oem cat back.

I thought the main restrictions were in the dp (pre cat and main cat) but having spoke to a revo franchised dealer they told me it wasnt a good idea to run a tappered dp with the oem cat back and that i should go full TBE for a stage 3 map

Thing is i dont want the extra noise associated with this and cost of buying a full TBE (£1000+) and really just want the supporting mods which are necessary for stage 2

any opinions form members who have tried this and are running stage 2 with just the decat DP and a CAI on a Mk5 GTI(200bhp)

Cheers

Yes you can, I've done yhis personally on my last two cars.  All the performance, none of the noise

When i spoke to Kev@Revo he saw no problem with me doing this, so the downpipe is in the garage ready to be fitted.

My ed30 has 3" Apr downpipe and OEM catback. Revo stage 2+.
No problem since 2009!

Great! thats exactly what im after, the power increase without the extra noise.....loud exhausts arent for me anymore

you can do it no problems, although i dont think you get ALL the performance.

i ran stg 2+ with just the pipewerx downpipe and then added the full tbe and i could definately feel a difference with the butt dyno as soon as i picked the car up.

but no idea what it equated to in terms of bhp/torque, i just remember Hurdy seeing my car on the ramp at Statllers and saying "that oem catback will be slowing you down"

I am running the toyosports 3" decat to standard cat back, it sounds epic!!!!! I had some timber hanging out the back yesterday and so had the boot open slightly, didnt realise how good I sounds from the out side.. Was awesome, especially higher in the rev range, I might drive everywhere with the boot open from now on!!

So would be a better alternative to STD down pipe and aftermarket cat-back system?

I dyno'd my piper non res cat back with my pipewerx 3" DP before and after and it gave me a whopping 1hp!!!

If your after more noise but not bothered about power then yes, go for a std DP with aftermarket cat abck.

If your after more power but not the noise then no, go for an aftermarket DP with stock cat back.

If your after noise and power then go for a full TBE.

I'm definately looking for power over noise, I'm not unhappy with the standard exhaust note.

Essentially it'll be cheaper to gain a little power than potentially a lot of annoying (subjective) noise.

Plus my budget wont stretch to a *new* TBE by budget I mean Mrs LOL.

Do you hear any noice improvement running a 200cel down pipe and standard cat back? Im looking for more power better flow and a deeper grawl would be nice?

[Janner_Sy]

yes.  imoit made it sound more like the 2.5T in the Mk2 Focus ST

My ed30 has 3" Apr downpipe and OEM catback. Revo stage 2+.
No problem since 2009!

Anyone know where to buy the adapters to do this?
I have a 3" Milltek sports cat and want to connect it to an OEM cat-back but obviously it won't fit without an adapter.

What's the difference between a tbe and a downpipe+cat back exhaust?
