ECOTUNE BMW E46 330D Decat Downpipe

Performance - You will enjoy reduced turbo lag and a noticeable performance difference throughout the entire rev range! The original downpipe has a near 90 degree angle into a restrictive "heat soaked" cat which is replaced with a smooth bend and unnecessary under bonnet heat is reduced. Turbo lag is reduced and the reduction in turbo temperatures has a direct effect on the air intake temperature. This promotes a cleaner burn and with the correct software, a higher power remap can be applied safely in the knowledge that your turbocharger is running cooler.
 
Economy - You will experience around a 2 MPG improvement over the original restrictive catalytic convertor depending on your driving style due to the reduction in your turbo and intake temperatures.
 
Longevity - Your upgraded dowpipe is over-engineered in 316 Marine Grade stainless steel and the flexible coupling in 304 Grade stainless steel, your new downpipe should outlast the life of your vehicle. You should also expect your turbocharger to have a longer life as temperatures are greatly reduced.
 
Perfect Fit - This downpipe was carefully developed using the Genuine BMW factory item as a template then improvements were made to flow where possible.
 
Noise - The only difference to the sound from your exhaust is a very gentle whistle from your now de-restricted turbocharger. This in no way has an effect on the exhaust note.
 
Quality - Built with over 20 years experience in all kinds of fabrication and welding you can be assured that the quality of your new performance downpipe will be second to none!
 
Guarantee - A lifetime guarantee is offered on the pipework and as the uprated stainless steel coupling is a flexible part, we offer a two year warranty on the flexi section.
