Power Flow exhaust are good for the money.

It's probally your heat shield rattling too.

If you do a search (button in to right hand corner) for both of the above, you should be able to find out loads more info.

 

yeah, i did the search, but while the discussions are long, the facts are vague

 

Bit of angle-iron and some jubilee-clips, mate.

I think the best you can do is tell them that your Cat's heatshield is rattling. The RPM you describe the noise happening at is in line with the problems I have heard of.

You shouldn't need part numbers - they'll have heard it all before!

 

okay thanks!

anyone have anything to add regarding the pipe? todays the day

 

The rattle could be one of a few things.

If it ONLY happens while braking it might be a pad rubbing the dust shield.

If its during normal driving, it's either the heat shield, front flexi-pipe or the bracket....

A full stainless system ought to sort you out!

 

Front pipe bracket to fix rattling on my 214 was GEX13002 i think

 

okay dudes, powerflow exhaust made and fitted, sounds nice!

but.....


it runs a bit lumpy under load at low rpm, and it pinks. any way around this, or is it part and parcel of having such an exhaust?

 

There is a bracket....the Rover technical bulletin is on my website....zipped file.

 

The kit bolts the front pipe to manifold joint area to 2 holes machined into the front of the engine block via this bracket. You would normaly fit this if the downpipe is ratling in the flexi joint area. However, if you're fitting a new downpipe anyway, try that first and see if the rattle goes....

 

thanks!

no new downpipe, only replaced from the cat backwards. rattle is still there. but now it also runs lumpy at low rpm in high gears. and it pinks when i rag it. is this a charaeristic of ST exhausts? it was fine before :\ (sounds nice tho)

 

The bracket will certainly stop the flexi rattle. I'm picking mine up satdee morning. Even with a new flexi there is a little rattle on ramps/bumps etc.

As for the stainless exhaust - I had a Piper Stainless system (cat back) fitted to my old Escort Zetec. This coupled with an FSE boost valve and K&N 57i meant that the exhaust created 'back-burble' whenever i came off the throttle. Sounded awesome - so much so that my next door neigbour went out and bought a Peco big bore for his Scooby!

The system never really felt 'lumpy' as such, but it certainly wanted a few more revs to get the most out of it compared to the standard system. At low revs in traffic I often had to drop a gear before accelerating because the exhaust was breathing freer than the standard one, and needed more revs to get the most from it.


Can't recall the system causing any pinking though... You might want to speak to a specialist Rover Tuning company and see if they know what the fault is. With the new system fitted your engine might want some of the 'default' ECU settings altering slightly (if that's possible on a Rover??) to allow for the better exhaust system.

 

If its at 2500 grand then its more than definate the bracket.

Seen this on 10+ plus VVC Coupes now and the bracket fixed them all.

A bit long winded, but the Rover Tech bulletin is here, with part numbers and fitting guide.

Note: Can be applied only to engines having two tapped casting protrusions
on the side of the cylinder block adjacent to the manifold / downpipe joint. This
casting modification coincided with the introduction of ‘K’ Series with damp
cylinder liners.
RE-ISSUE INFORMATION:
Change to warranty complaint code.
Note added reference unnecessary downpipe replacement.
PROBLEM:
EXHAUST DOWNPIPE RATTLE - BRACKET
Complaints of rattle, vibration or resonance at various engine speeds.
May be more prominent at around 2400 RPM and in some instances only when
engine is cold.
May also be described as boom on overrun.
CAUSE:
Exhaust downpipe unsupported.
ACTION:
Fit Bracket Exhaust Downpipe (kit) GEX 13002
Fitting instructions:
1. Remove the two manifold to down pipe nuts nearest to the cylinder block.
2. Position bracket over studs.
3. Secure opposite end of bracket to the 2 adjacent tapped casting bosses in
the cylinder block, use the 2 X M10 flange bolts supplied.
4. Disconnect oxygen sensor cable and fit the heat resistant sleeve provided to
cable, slide sleeve fully up to the sensor body.
5. Fit the remaining 2 X M10 flange nuts to the protruding manifold studs and
tighten to secure bracket, torque to 55Nm.
6. Finally tighten the bracket to
block flange bolts to 55Nm.
7. Re-connect oxygen sensor.
Downpipe replacement:
It should not be necessary to
replace exhaust down pipe in
addition to the fitment of bracket.
Always apply this bulletin first and
assess improvement. Only in
exceptional instances will it be
required to replace downpipe.

bracket info is tops, i'll get this sorted, as for the exhaust, here is the story so far..

the new system is loud, damn loud and i think here is no back pressure whatsoever. i;m having it remade next week to take the deep drone away.

i used super unleaded petrol today, and the pinking went. not sure what that's all about, i may disconnect the battery to reset the ecu, let it relearn the powercurve.

will adding the 57i filter help with the lumpyness, or could that make it worse?

i dont want to go mad and turn this nice car into a mk3 escort type boy racer mobile (apologies to them, i dont mean any offence) if you know what i mean
