Please give me your opinion I have an 04 40th anniversary gt conv. and i put 40 series flowmasters on my car and it already has stock H pipe so if i order a whole new catback system should i order a H pipe or x pipe and will it have cats on it. if not will it void my warranty. If u had my car what would u do to the exhaust and other miscellaneous things to improve the HP
Ok first thing is first. The warranty is totally up to the dealer when you bought the car from. You have to talk to them and see if you are allowed to install an X or H pipe and keep your warranty. I know that they will not keep your warranty if you get an off road H or X-pipe (No Catts). If you go with no catts just make sure you get a set of mills or a chip so that your check engine light doesn't come on. A cat-bat system should be no problem, but like I said make sure you CHECK WITH THE DEALER. Now if you ordered a new cat-bat system I would go with an H-pipe simply because I prefer the deeper sound it gives you with the 2v. I would then get a set of Long Tube Headers (Kiss your warranty good bye at this point) to complete the exhaust. After that possibilities are endless. It depends on what you want out of the car. And what you want to do in the long run. Hope this helps.
