Transforms the experience with the car, at any speed, just insane at full charge and downshifts are the end of the world sensation😂. Superb quality ans fast delivery Thanks guys

Great customer service every time and high-quality products

The Team at Valvetronic are so friendly and helpful, getting this exhaust all the way to South Africa. Thank you!

Great exhaust I put it on a bmw b48. Honestly would recommend upgrade to a b58 rather than putting it on the 4cylinder It sounds a lot better than the stock but I imagine on a b58 it would be just nasty

Everything was great thank you

I can’t say enough good things about Valvetronic Designs and their customer service. I ran into an issue with my exhaust system, and from the very beginning they treated me with respect, kept me updated, and genuinely cared about making things right. They went above and beyond by replacing my entire muffler kit and exhaust tips at no cost. That’s an incredible gesture and around $2,000 worth of products. Companies don’t have to do things like that, but Valvetronic Designs truly stands behind their products and their customers. It’s rare to find a company that backs their products with this level of support. They turned a frustrating situation into one of the best customer service experiences I’ve ever had. Their professionalism, communication, and willingness to help have earned my trust, and I’ll continue recommending them to anyone looking for a high-quality exhaust system. Thank you again to everyone at Valvetronic Designs for taking care of me. You’ve gained a lifelong customer, and I couldn’t be happier with how everything was handled. for surely when I get my new car, I’m going to be purchasing an exhaust from you guys valve. Tronic designs is the best company out there for exhaust anything for buying from this site is 100% guaranteed and they take responsibility into their own hands and actions into themselves and they take accountability for their product and showed that even without warranty they back up their products thank you very much once again best place I’ve ever shopped at and they standby their word loyal and they are very nice and they respond great and they have amazing customer service and people working there…. Amaury Alvarez Great customer survey thank you guys great team

For 2025 330i mine is the m sport but I noticed the stock pipe is about 3. 5 inches valvetronics is 4in just needed a bigger clamp until I got it welded sounds great bolts on perfectly just wrong pipe size

best communication

Amazing product! Love the sound of my car now with the dual exhausts. Nice added sporty look to my vehicle as well. Would definitely purchase again if needed.

10/10

Great descriptiop. Fast shippind. Wide range off selection. Recommend!

Valvetronic a l air sérieux. J ai commandé le produit. 20 minutes après ils ont emballé et expédié le produit. Très bien emballé d ailleurs avec de la mousse dur et épaisse. Pas de soucis de transport.

Purchased this for my 991. 1 Targa and as soon as I put my foot down, the valves open and the engine screams get out of my way, a massive smile immediately spreads from ear to ear. Workmanship is amazing, sounds amazing and I LOVE it. Only issue ove notes is the install was a little tricky and I still can’t get the back pipes evenly level. The package did arrive in rather rough shape so I’m wondering if it’s not slightly bent somewhere? Would be 5 stars if I could even out the back pipes

Fast shipping and customer service was quick to reply to any questions I had.

Excellent solution for my car and well built. Great customer service when I had an issue they got me fixed up quick

High quality product, easy installation, great exhaust tones.

Great product and fast shipping

Easy ordering, mufflers arrived next day
