Question is, how much would we feel a 30-40 hp increase on a car this heavy?

Yeah those RPI guys are pretty smart. Big ups to them for always PROVING their product which doesnt go for most performance mods out there. I would urge ppl to check out their products.

i don't think its appropriate to be referencing "garden pots"...
if this were a japanese vehicle forum, then the rice bowls would do...but seeing as how we're german, i think we have to go with beer stein diameter tips..

I would be very interested. Just picked up an X6M today. Awesome, however I believe the exhaust note and engine growl was more aggressive in the X6 50i I sold.

LeMansX5, What is the difference between Eisenmann Exhaust and the GT Haus Meisterschaft Exhaust?

Which one would you say is better? This is for an 09 X5 4.8.

This is fairly simple yet very complicated. Long story short:

GT Haus used to be known as Eisenhaus and they were the US importer of Eisenmann exhaust. Supposedly they ripped off hundreds of customers telling them they were selling the superior Eisenmann exhaust but in fact were selling them an in house knock off that was in all likely hood made in Asia somewhere instead of Germany like the other true Eisenmann exhausts. There was a whole fiasco and you could see and hear the difference in quality. Eisenhaus lost there right to be the US importer and IND stepped up to the plate bringing in Eisenmann exhaust. Eisenhaus went underground for a bit and then reemerged as GT Haus.

RPI is such a smart choice. I could have done Eisenmann, Meister, ASR or Dinan for my M and I chose RPI. Most of the Eisenmann owners in the Tri-State Area have heard my RPI set-up and loved how much better it sounded and how well the car pulled compared to theirs.

On top of that, RPI's customer service is far superior and the best I've ever dealt with. That's probably because you deal directly with the owner himself, not a distributor.

Oh, and prior to RPI, I had Supersprint. That system lasted about a month.

Yep. And they don't rape you on pricing like Eisenmann.

Oh boy...tell me you didn't just ask this question. Check out M5board for that answer.
