Hey guys just wondering I have a n/a v6 with the single cat exhaust and I want to change it to the l67 twin cat exhaust will it just bolt straight on?
No it won't. You will need the twin cat front pipes as well. Or get yours modified and fit twin cats and the flanges. Or you can fit extractors, twin cats and have twin outlets. It won't make it any louder though.
When you get your twin cats you need to buy the pipes either end of the cats as the pipes are different on yours. Your pipes jion at the cat. I think you will need a joiner after your cats
