Description:

We are proud to introduce our VRSF Upgraded Down Pipe for your F26 X4 M40i/M40iX. This downpipe is THE best bang for the buck power mod available and it is available in either a catless configuration or you can opt for our 200-cell high flow sport cat configuration. Back pressure is significantly reduced when eliminating the restrictive catalytic converter in the factory downpipe which results in faster spool, increased horsepower & a more aggressive exhaust note.

Every VRSF downpipe is constructed from mandrel-bent, SS304 grade stainless steel and our flanges are precision machined in order to ensure proper fitment every time. We also include a lifetime warranty as well as our “No Hassle” satisfaction guarantee (including fitment). For ultimate performance, we offer Cerakote’s best thermal barrier coating which helps keep the hot air inside the exhaust and out of the engine bay which decreases overall intake air temps along with engine and transmission oil temps. This High Temperature Ceramic Coating is made to withstand temperatures up to 1800F

Attention:

While we do offer a lifetime warranty on the downpipes, we only offer a 1 year warranty on the ceramic coating and high flow cat.

Features:

  • Made from mandrel bent, tig welded 304 grade stainless steel.
  • Smooth radius bends decrease turbulence and increase flow.
  • 200 cell high-flow sport cat & catless options available.
  • Precision machined CNC flanges made from SS304.
  • Gains from 20-25hp with tune.
  • VRSF Lifetime Warranty

        Adorable special occasion suit for boys
        Size: 5, Color: Light Blue, Size: 5, Color: Light Blue
        I ordered this 3-piece suit for my son and even though it’s currently a little too big for him, I couldn’t resist keeping it because it’s absolutely adorable! The quality really impressed me right out of the package. The fabric feels lightweight and breathable, which will be perfect for warmer weather, and it has a nice polished look without feeling stiff. The set comes with a blazer, vest, and pants, and each piece is very well made. I love the little details like the lapel on the jacket, the adjustable strap on the vest, and the adjustable waist on the pants, which will definitely help as he grows. It looks like a much more expensive suit than it actually is. Even though my son will have to grow into it, I’m already excited for him to wear it. I’m thinking it will be perfect for Easter next year or any special occasion. It’s such a cute outfit, and I love that the pieces can be mixed and matched for different looks. Overall, I’m really happy with this purchase and can’t wait to see him wearing it! The blue color goes well for any occasion and I may have to order my husband a suit in matching shade of blue so they can be twins. The size looks accurate for boys 5T. I took a picture to show the pants next to a pair of unwashed Oshkosh B’Gosh brand straight leg 5T boys denim jeans.

        Size: 5, Color: Light Green
        I’m so impressed with this **boys' linen summer suit**! 👔🌞 It’s the perfect outfit for warmer weather while still looking sharp and stylish. The **linen fabric** is lightweight and breathable, making it ideal for those hot summer days. My son looked fantastic in it, and he was comfortable all day long, which is a big plus! The suit fits **true to size**, and the cut is modern yet classic. The **jacket** has a great, tailored look without being too stiff, and the **trousers** are just the right fit—not too baggy or too tight. It’s a very **polished** look for events like weddings, family gatherings, or holiday parties. I also love that the **color options** are vibrant and fresh, perfect for summer. The suit is **easy to care for**—I was worried about linen wrinkles, but it’s held up well after a few washes, and the fabric still looks crisp. Overall, this **boys' linen summer suit** is an excellent purchase for any special occasion or just to make your little one look extra sharp during the summer months. **Comfortable, stylish, and durable**—highly recommend! 🌟👔

        Nice summer suit for my son
        Size: 6, Color: Light Green, Size: 6, Color: Light Green
        I got this linen suit for my 7 year old son and it looks really nice on him. The set comes with the blazer, vest, and pants, which makes it look very polished when worn together. The material is lightweight and breathable, which is great for warmer weather. It has that classic linen look but still feels comfortable enough for kids to move around in. My son wore it for a few hours and didn’t complain about it being uncomfortable. I also like the little details like the pockets, the adjustable back on the vest, and the adjustable waistband on the pants. Those features really help with getting a better fit. Another nice thing is that you can mix and match the pieces. He can wear the vest and pants for a slightly more casual look or the full suit for more formal occasions. Overall it’s a really nice suit for kids, especially for events like weddings, family gatherings, or school events. My son looked great in it and it worked perfectly for the occasion.

        Summer wedding kids suit
        Color: Navy, Size: 10 Years, Color: Navy, Size: 10 Years
        Bought this suit for my son in the 10 youth size and honestly was pleasantly surprised by the quality for the price. The navy color looks sharp and dressy without being too stiff or uncomfortable. The material has a little stretch, which helped it fit nicely and made it comfortable for him to move around in. The adjustable waist was a huge plus, especially for growing kids. It fit true to size overall, though the blazer sleeves were slightly long on my son. The pants had a nice slim look without being too tight. We paired it with white sneakers for a more modern look and it came out adorable. This would be perfect for weddings, graduations, concerts, communion, school events, or family photos. Overall, very happy with the purchase and would definitely buy again.

        Very Modern Handsome Suit
        Color: Grey, Size: 7 Years, Color: Grey, Size: 7 Years
        This is an incredibly sharp looking suit for the little guy. Great price and features, too. I made a mistake in sizing up instead of down and first one was too sloppy on him and would need alterations. He is thin and very thin in the waist. There is a lot of adjustment with buttons in waistband and coat hides the bunching. This shirt and coat will easily take a fuller body than slim I believe. He loves posing in it and feels very classy. Best purchase for a formal suit that will last longer than most kids clothes size wise. Felt bad about returning but careful folding and packing got it good as new.
