Ello,i just need som opinions,i have 2 full magnex exhaust systems, one is for a 2.0 16v for a Nova and the other is frm a MK1 1.8 8v Astra GTE, would i b able to mod the Astra exhaust to fit my 1.6 8v Nova and put the 2.0 16v back system of the exhaust to the 1.8 8v Astra exhaust,or is it not worth the stress. Sorry if i confused any of you and cheerz for any help.
