M135i /M235i tuning group buy (inc new 4" turbo downpipes) !

Post by performance developments » Wed Mar 19, 2014 8:12 pm

Lots of people are asking about group buys for various parts so we have placed large stock orders with various suppliers and have the following left up for grabs, I will edit the numbers as and when people place orders:

11x JB4 systems (including USB cables) RRP £501 sale price £470

7x 3" decat downpipes (2012/13 cars with pneumatic turbo solenoids) RRP £229 sale price £199

7x 3" 200 cell downpipes (2012/13 cars with pneumatic turbo solenoids) RRP £599 sale price £565

15x 4" 200 cell downpipes (2013/14 cars with electronic turbo solenoids) RRP £659 sale price £619

11x BMS intake kits (new revision that DO NOT cause CEL fault and don't need JB4) RRP £239 sale price £22511`



If you are interested just add your name to a list with the part(s) you want. Delivery is £9 for the jb4 systems or £12 for anything else. If you purchase 2 or more items the delivery is still only £12.

As this is a group buy, we will leave this open until April the 15th, you are welcome to make the order and payment anytime up to this date but deliveries are not likely to leave us until this date as we are awaiting manufacture and stock of some of the items.

Payment for orders can be made on debit card by calling 01914357021. All prices are fixed and non negotiable, products are offered on a first come first served basis.

Is there not a decat for the m135i with electronic solenoid? Cheers

Can you put me down for the intake anyway?

That product is about 10 weeks away from release at present. May be sooner but will update people on its progress.

The prices are the best possible prices that we can give, the price of these products is already well under both the RRP of the item, and all products are sold at a price point which is way lower than any of the equivalent products from other manufacturers. It's impossible to discount items by 15+ % when the profit margins are less than this.

Are the scorpion downpipes not classed as equivalent products? £202 delivered for decat and £472 delivered for sports cat....

This thread isn't about scorpion decats or sports cats, feel free to purchase one of those items if you wish. But if you want a comparison, our decats use billet steel flanges at both ends as opposed to a flared tube outlet, so not comparable. The BCS sports cat elements are also very different.

I am interested in your sports cats but could you elaborate more on this point? Thanks

I will post a full answer to this question tomorrow as I need to be somewhere shortly.... But essentially not all sports catalytic converters are the same.

Do the air intakes improve power at all?

Yet to be tested on a UK dyno, USA tests show average of 10bhp peak power gain, but until iys proven on a correctly calibrated Dyno Dynamics or Dyno Developments machine I cant say, but they do sound amazing!

Had the JB4 been fully adapted to the electronic boost solenoid now?

Not yet, but this will be sold as an optional add on at a later date, for now the JB4 still works perfectly with these engines with fantastic gains.
