GMG WC-RS4 Sport Exhaust system for 2007+ B7 RS4
GMG introduces its WC (World Challenge) sport exhaust system for 2007+ B7 RS4 owners. The GMG WC RS4 systems offers the discriminating RS4 owner the performance, power and sound worthy of the high revving RS4 engine. Designed, tuned and built in California to GMG's stringent standards. The cat back system is 100% emissions legal and is a direct bolt on replacement for the factory system. Made of T304 Stainless steel throughout (all tubing, inner core and wool packing are stainless, most other brands do not offer this) the system is 20 Pounds lighter than the factory system, offers two larger GMG specific tips, and a center sport resonator which eliminates unwanted cabin resonance. The proprietary cross over center section not only offers additional power by balancing exhaust gas pulse coming from the engine but also adds to the unique sound that only the GMG WC system can offer.

Systems come fully polished and are a direct bolt on replacement utilizing your existing factory down pipe to exhaust clamps ensure no exhaust leaks.

Fitment: 2007 B7 RS4 models USA and world wide models only. Does not fit B7 S4, GMG B7 WC S4 system coming soon.

Price: $1499.00

They are an excellent company.
I have been hoping they would come up with a package for the RS4, ie exhaust, air box and ecu mod but so far they have only produced the exhaust.

thats <beep> hot sound, sound a lot different compare to miltek exhaust. i might consider getting one, does that have th exhaust valve flap like the std exhaust

I too think that sounds lovely, not sure about the tailpipe shape but I would poss give one a go. Does that include shipping, if not, any idea how much it would cost to ship to the UK.

They would probably send it FOC but remember you will have to add VAT to the INVOICE PRICE.( if you get my drift).
You will normaly pay the vat to ups along with a small duty fee upon delivery.

yeh someone try do a group buy lol.

Yeah, very nice. Nice wheels too - what are they?

What a great looking & sounding system! Probably a decent price too once all stoppages included. Agree the tailpipe finishers look at bit naff. Wait to see a review, will post if it appears in European Car magazine as they test most US tuners parts
