The official price is set at $2399. We are making a slight change that will bring the cost down. Guys who want to bolt their secondary cats back on can buy our optional adaptor kit for $65.

We'll have an intro/gb price for the 535i exhaust at: $1950. This price will be good for the first 12 customers. Production will begin today and they will be shipping in about 45-50 days.

Specs/Details are:

- T304 Stainless Steel
- V-band aero connections
- True Dual exhaust (dual piping, dual mufflers, etc)
- RPi limited lifetime warranty
- Complete BOLT ON system (no modifications)
- Massive hp/tq gains even under heat soak

 

that's a great price for an exhaust with such high gains. I paid close to $1800 including install for just the section 3 Dinan. the performance was no where near the RPI exhaust lol! Price vs HP gains= no comparison.

FOR THOSE WHO ARE WORRIED ABOUT WARRANTY ISSUES: The dealership will void Dinan products if the dealership can prove that the source of the problem is from the actual modification. I have also spoken to a SA @ Sterling BMW in newport beach, ca and according to him modificaitons such as exhaust, suspension and wheels are usually are never voided. The SA himself owns a E60 M5 with a ecu reflash and full catless race exhaust. I have taken my 535i in to the dealership with my wheels, coilovers, exhaust, scoops, and air filter and NEVER have had problems.

 

Get on the list...This is a great price they are offering...

If the exhaust is bolted onto the downpipe, that mean we will loose the cat, right? If that's the case, I wonder how smelly it's going to be...

 

if you read the post before, there is an adapter you can purchase for $65.00 to attach your stock cats back on.

 

does it fit the 535xi wagons?

 

That's a really nice gain! Did you guys happen to dyno the car with a wideband O2 pickup in the exhaust? If so, what was the before and after air fuel ratio?

 

I saw that, but I am just wondering how smelly it is without the cat...

 

The smell wouldn't be bad at all since the primary cats are not removed.

 

thanks for your info...
