Not from the shipper but because they were 2 heavy objects thrown in a box. The exhaust ports don"t match. Terrible quality welds, welding wire sticking out, nothing deburred. There is no way I would put these on my vehicle. Now I get to send them back to Canada from Alabama out of my pocket! --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/121634894-catalytic-converter-replacement-for-b-m-w-128i-325x-xi](https://www.desertcart.tn/products/121634894-catalytic-converter-replacement-for-b-m-w-128i-325x-xi) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-05-31*
