I've only done 1,000k's with the exhaust fitted and is still fitted to my E92 M3.

I can arrange fitting and a before and after dyno run at a additional cost.

System is located on Sydney's northern beaches in Cromer NSW.

I purchased the exhaust for a little over $3k, I'm happy to let it go for $2,800.

I'm tossing up between getting a catted X pipe from m3 world and keeping the stock rear muffler, or just bite the bullet and get a full akra system.

I had a catted X pipe with stock exhaust, this combo seemed to produce excess fumes and a bad smell. I've since switched to stock X pipe with an IPE exhaust, very happy although I now wish I'd tried the IPE with the catted X pipe to see if it was just a poor combo previously.

If you change from a stock X pipe to any X pipe and a stage 2 tune the car you will have increased emissions, you are going from stock 2 x 600 CPSI cats per side to 2 x 200 CPSI cats per side so you will get some slight difference in smell but you would have to be very sensitive to smell to notice. Any combination of rear section would have been exactly the same in terms of emissions. or smell. Its when you drop to 100 CPSI cats smell increases quite a lot and staining of the rear bar starts

This combination for a few cars has been really successful as it gives great increases in performance and sound whilst only bumping sound levels up a small amount using the OE rear exhaust

Adding the cats to your system will make a big difference, full catless is risky as its a $2000 fine per cylinder (in QLD) and defect notice and it is a lot louder plus you get a lot of staining on the rear bar. This is why I always try and convince people to avoid catless, the extra performance you get does not justify the risks of heavy fines, staining and its much harder to quieten down.
The smell of full catless is highly obvious to that highway patrol cop on a motorcycle
You can easily add cats, just send the system back and it can be turned around in a few days at way less cost than any other options. The best option with as a daily driver is a full system, the X pipe with HFC and resonated and the rear section with valves.
A loud system sounds great to others from outside but is hard to live with on a daily basis for most

I agree with Dave... Aftermarket xpipe with high-flow cats and resonators is the best option based on the research I did. Still good performance gains without the smelly and risky downsides. As for a valved-catback... perfect for daily driving or if you have PITA neighbours!

The perfect combo for me has been the stock X pipe with Stage 1 BPMSport tune, and a valvetronic exhaust. The power and drive ability improvements are really good. If you don't mind increased emissions, an X pipe with high flow cats and a Stage II tune kicks it up another notch

Wouldn't it be 1 x 200 CPSI cat per side? As in two cats in total?

You're not wrong there Rob... X-Pipe alone is a lot dearer than that


Valves can be retrofitted but the muffler section has to be returned for fitment of the valves and supply of the wiring harness, transmitters, receiver, vacuum solenoid valve and brass fittings.

I know Stewart Jackson at BMR Autowerks can do the job down south if sunny Qld is not the preferred option but by the time you add the valve kit and the fitting labour you are near enough to a new set.

Valves make all the difference on this system especially with a stock X pipe which has more drone than the X-pipe designed to run with these mufflers
