X Series exhaust parts are split by chassis, and interchangeability is lower than on the sedans: vehicle weight, ground clearance and rear structure all affect where the rear section and tips sit. This page collects TITANVEIN X Series downpipes, cat-backs, valved axle-backs and tips.
Because the range covers very different vehicles, this page works as an entry point: narrow down to a model first, then confirm the chassis code against the Fits field on the product page.
What to check before ordering
- Identify the exact model (X3, X4, X5, X6) and chassis code before choosing a part.
- Tip length depends on the rear structure — this matters more on X Series cars.
- Whether the downpipe needs a heat shield depends on engine bay layout and use.
FAQ
Do X3 and X4 rear sections interchange?
Some parts do within the same chassis; nothing crosses generations.
Is an SUV louder after an exhaust change?
Cabin insulation is usually better, so the change often feels milder inside than on a sedan.
