check out bosal exhausts website as this includes full diagrammes of the exhaust differences... I have looked and bosal list the connector is the same part for all gti model's and the size changes on the first downpipe (54mm clamp v 60mm clamp) so It should bolt straight up?? And if it dosent you need a bosal 265-119 (357 253 141A vw part) clamp/sleeve
