@scrapen Just wanted to say, thank you for recommending the Vibrant and the videos you posted. Added LTs to my truck and swapped to the Corsa Touring from the Sport at the same time, and it was still just so dang loud. Especially cold starts and shifts. Didn't expect that, really thought the Touring would tame it.
Found this thread and slotted the Vibrant in right before the muffler, and wow! It is absolutely perfect now. To me its even more throaty/tougher than just the Corsa Sport w/ stock manifolds. Thanks again!
