Exhaust, Intake and Intercooler Fitment: How to Confirm Parts Fit Your Car

Introduction
Fitment starts with the chassis code, not the badge on the trunk. Here is what we check before any part ships, and the information that lets us confirm your car in a single exchange.

Start with the chassis code, not the badge

Most fitment problems do not come from a badly made part. They come from two cars wearing the same badge that are not the same car underneath. Badge names are marketing. Chassis codes describe the platform - F80, G80, G90 - and those platforms differ in floor pan, tunnel shape, mounting points and rear section even when the front half of the car looks identical.

What we ask for, and why

Four pieces of information settle almost every fitment question:

  • Chassis code - the platform, not the model name.
  • Model year or build year - facelifts change the front end and the underbody.
  • Body style - coupe, sedan and convertible can diverge behind the midpipe.
  • Market - US, EU and JDM cars carry different emissions hardware and front-end packaging.

A VIN resolves all four at once, but it is optional. A chassis code plus a photo of the existing part is usually enough.

Why the rear of the car is the usual culprit

Front sections are shared far more often than rear sections. Turbocharger placement, charge pipe routing and crash structure are frequently common across a platform, while the tunnel, rear subframe and bumper cut-outs are not. That is why a part confirmed for one body style is not automatically correct for another.

Confirm before you pay

Send the details above with a photo of the joint you need to meet, and we will confirm the correct item and flag anything that needs attention. The cost of asking is a short message. The cost of shipping the wrong part across an ocean is a return, a delay and a re-order.

You can browse the range by platform on our Shop by vehicle page, or send us your details and we will point you at the right part.
