Hi everyone, i have a vp v6 commodore, manual. it has wildcat extractors + 2.5" HF cat + 2.5" Cat back, the cat back has an offset muffler which is taking out a heap of the sound of my exhaust, so i have a hotdog that im going to put in place of the muffler, once i have done this i will see if it sounds nice and if it is a bit loud would putting a resonator on the rear side of the diff do anything, please tell me what this would do, and also if i put a 2nd hotdog on the rear side of the diff instead of a reso, would this still be louder than the muffler i am removing ?. please help me i just want to know what certain things do . cheers
