Want a sports cat downpipe to make my car louder, i'm hoping a 200-300 cell will do that and i'll take any associated power gains.

Both of the above products use HJS cores but only fabspeed mentions and is talked about in the context of not creating CEL errors.

In the UK the difference in price is only about £100.

This forum generally seems very pro fabspeed which is fine but what are people's thoughts vs the Milltek equivalent?

I believe the Milltek is the same design as the 300cell mentioned here, correct?

Never heard of Milltek, but I'll stand by Fabspeed to the end. I can't say enough good things about it!

[mike@x-ph.com]

We offer both, with Fabspeed being by far the most popular.

Its also the more proven option for us, +1 for Fabspeed

Ok so I know the forum is mostly US folk. I spoke to a garage/tuner that spoke more highly of milltek build quality.

I've read also the milltek part looks much more OEM which can be useful depending on what garage is looking at your car..

Milltek is the same as Akrapovic and HJS 300 Euro6 cats. A review can be find here:

My HJS is going to be installed next week (already have a MPE)

I prefer bassier sound than loose nails 'raspy' sound. I like burbles but not explosions or pops if that makes a difference?

TBH thinking milltek downpipe now then later adding their exhaust system. Will a HJS 300Cell offer power benefits also?

200 CEL will not give you a raspy sound, its mild increase. Catless adds raspiness

Thank you, raspiness to me sounds 'broken'

I would get neither. Both are illegal in Washington (you are not allowed to alter the manufacturer's emission system ).

I installed fabspeed and I can tell you that it is one if not the best mod I have done to my M2, it transforms the sound without being too loud, you will be able to hear pops and bangs and will put you a smile on your face!! really nice mod; you can start by installing it with stock exhaust and then move to an exhaust if you want more sound, I have MPE as well and just love the sound it makes.

I'm going to go for Milltek (branded HJS) as is Euro6 smog compliant

Sucks to live in Washington. I'm several thousand miles away so should be OK hehe

I remember reading about this on another thread. Changing the DP out and leaving a stock exhaust would make it nearly impossible for your average patrol cop to ever know anything was different.

I mean I wouldn't risk it if I lived in WA either, but I just can't fathom how they'd actually catch people on this outside of an emissions check or something.

Lots of states have a mandatory emissions check.

Yep, one more year before we lose mandatory emissions testing. But the dealer can turn you in when you get service. Not worth the risk.

Just gotta find the right dealer.

I had a friend with an M2 who had a body shop threaten to turn him in when he asked for a quote to install a down pipe. This is an excellent body shop that (unfortunately) I have used several times. They even have installed some of my M Performance parts.

That sounds like a WA thing, which is going away next year.

But, gotta find the right body shop, too. I drive passed many dealers and shops to get the service I prefer.
