The brand new R-Sport Decat Downpipe is finally here to suit BMW M140i and M240i models.

Manufactured from hugely strong T304 spec stainless steel, this downpipe produces absolutely fantastic results. Running a better flowing downpipe than stock, reduces the back pressure in the exhaust system, allowing for greater power and torque from tuning. 

In our extensive testing with the help of the guys at Maxd-Out, we found the fitting of this downpipe allowed gains of upto 20bhp!

The R-Sport Decat Downpipe is 4 inch in diameter tapering down to 3.15 inch meaning it will fit to both the stock exhaust system, and most aftermarket systems which retain the 3.15 inch diameter. 

As with all R-Sport exhausts, this BMW downpipe is direct fit and very straightforward to install with very few tools required. We also offer fitting on these at Pumaspeed HQ in Wakefield, West Yorkshire.

There's no need to pay big name prices for your downpipe, R-Sport exhausts are amongst the best on the market without the crazy price tag! We're that confident in our exhausts that we offer a lifetime unlimited mile warranty for the original purchaser. 

This R-Sport Decat Downpipe fits the following models:

- BMW M140i F20/F21 2016-2019

- BMW M240i F22/F23 2016-2019

- BMW 340i F30/F31 2016-2019
