powerflow stainless downpipe-back

[Sonic]

Hi,

The rear silencer on my stock exhaust is making a pretty nasty sound, there is a nasty blowing sound from under the car, and i wanted to get a new exhaust system anyway (with a sport cat)... so now seems like the perfect opportunity.

Only problem is, as this one needs sorting ASAP because of the existing problems, its going to have to be done on a budget.

A company down the road in Morecambe that i use for all my alloy, tyre and aircon needs say they do custom exhausts also. Quoted me on a "powerflow stainless steel downpipe-back sport-cat system" @ £480.

Now i know they would do me a good deal because i use them alot, but this still seems pretty cheap.

Does anyone have any advice on custom built exhausts, or know anything about powerflow?

Cheers!

My old Cav Turbo had a full custom s/s Powerflow system, and it may not of been the best available, but it certainly did the job!
My mates Cav SRI has a Powerflow rear silencer, and that is fine too, as are quite afew other cars Ive seen over the years with them on.
The most common rule regarding them seems to be based on the skills of the fitter.
If you do get one, just make sure everything is as you want it before parting with the hard earned!

Powerflow!

I should *slap* you for swearing on the forum!

They use 430 grade steel which rusts to f*ck.

All of their back boxes are generic and not made to fit your car specifically.

i.e the exit on the box could be on the wrong side of the box so they run it around to the right side!

Steer well clear!

There's a few good exhaust places if you search the forum. Bibby had a good one that did his for a very good price.

No rust on mine, or my mates...
Mine had been on the car for over 2 years.

Thats a new one on me!
When I went with my mate to get his fitted, they had a huge selection of boxes, the correct one was selected for fit and exit location. Then the tail pipe was chosen and cut to length to suit.

Steer well clear!

As I said before, they are not the best, but can be ok for a tight budget.
Its not a Milltek obviously, but then you are not paying Milltek prices!
Plus they do have a lifetime garantee for as long as you own the car, and get it checked once a year/get the garantee stamped.

The hanger broke on my rear silencer (driving on the bumpy back road to Pod LOL)
I called them the next day, drove over and they fixed it free of charge

PM 'Pete Reeve' or phone him on 01214760034 about a Milltek, he'll be competitive on that price but you will require it fitting. A good local garage will be able to do that, just make sure they align the cats properly otherwise they hang low. They should be horizontal.

This is what I did and the Milltek is factory fit and great finish. No messing about IMHO.

My vote would be the Miltek if it was my money. I am still looking forward to getting one on my car, one day....

I would get on my back and fit it myself too, so that I know it is on correctly. But having seen your post about sissor jacks, I would leave it to the Pro's.


Cheers,

Steve

IIRC Pete Reeve is doing Milteks at 450 quid, it would be rude not to. A mate of mine bought an A6 avant V6 with a powerflow system on it, sounded awful, took it off, pipes very small diameter, sold on ebay for 50quid nuff said.

[Jamo]

Milltek is the best sounding, Longlife are very good also.

I'd go Milltek if you can afford it, it just depends on if your going for big bhp later as if you are dont just buy a back box and get a full 2.75" or 3" system.

I am surprised no mention of the Supersprint system after reading good marks from MRC

Couldn't remember that name!

Couldn't remember that name!

well at least from Mihnea's words

"Yeah supposedly anyone can build a decent exhaust for an S2 or an RS2 and for a good price at that as well!!! Yeah right!

Long story short: I've mapped dozens and dozens (probably around 50 in total if not more) of RS2s, with stock exhausts and with dozens of aftermarket systems on them. One thing I have noticed is that boost control remains close to the same whether the car has standard or performance cats or no cats on a standard or Milltek downpipe, if I want a car to run 1.7 Bar peak then it'll do it just fine and no major adjustments are needed to the N75 map so the car runs those boost levels.

That was UNTIL I got to do a car with a full Supersprint exhaust on it. At first I thought the N75 was broken because I got 2.2 bar spikes all the time. Then I changed the N75 and I was still getting 2.2 bar, more like 2.3 in higher gears, which means the old N75 was shot but wasn't working hard enough. It finally took about 2 extra hours to remap boost control properly so boost wouldn't exceed 1.75 Bar. The result was well worth it as the car produced 375 PS on the dyno that day, for 305 standard with the Supersprint exhaust and stock ECU.

So honestly, don't think that all exhausts are created equal, because they aren't. I've since done probably around 15 RS2s with Supersprint exhausts on them and they have all produced better than your average "RS2 with full exhaust" results/performance increases.

I can only attribute the increase in boost with the system on to the fact that Supersprint systems have much lower backpressure than all other systems available.

Just my 0.02.

I'm highly considering Supersprint and in time will have an MRC map. Also got a quote from Pete Reeve

S2 ABY full system inc Large bore down pipe and high flow sports cat £1000
+ shipping

Mmmmm Supersprint....

Cheers for the comments guys

Jamo - you've officially made me more nervous

Ive spoke to Pete Reeve the other day and got some quotes for Milltek kit.

The Downpipe-back is almost twice the price for the Milltek, and that's without any shipping and fitting. Obviously its way better quality, but not something i can jump to (why oh why did i get those new alloys and tyres!).

The reason i am wanting to get this done ASAP is because as i said there are a few problems with my stock exhaust, and im a little worried about doing damage unless i get it sorted. If i would wait a month, then id be more tempted to go for the real exhaust. :mischeif:

The powerflow website says they use "T-304 none magnetic stainless steel". This doesnt sound like the 430 rusting stuff you were warning about Jamo?

As Dest said - they do come with lifetime guarantee. And ill do everything i can to assure that this S2 will be looking and running as good as it does now, in 20 years time.

How bad is your current system?
Could you not go down the same route as me, and buy it bit by bit as finances allow?
I have just got a Milltek rear silencer for £300 (that is RRP, I paid slightly less) and will add the centre sections when I can afford them

[Sonic]

Well the rear silencer is making nasty sounds and there is alot of blowing from the centre section - how bad - thats the problem, im no mechanic so ive no idea if its going to do any damage.

Buying piece by piece is something id not really thought of.

I guess i could get the cat-back thus sorting out silencer and probably the blowing. Id then get the sports cat later, and would have a couple of spare parts e.g. the 'Y'?
