could i install a flowmasters or magnaflow exhaust system on my cobra by myself...would it be hard and does it require welding, and does it come with instructions?
If you're going with a catback system, you can do it yourself with help from a friend (and beer). Just undo some bolts and remove them from their hangers. It's pretty straight forward. If you're just going mufflers, then you'd need them welded in.
ok new question...my dad said he would pay like 400 for the exhaust and that is enough for the flowmasters system. then i was gonna pay like 175 to get a demolet intake. would i get more horsepower from that set-up or should i take the 175 to add to the 400 to buy the magnaflow system. so 575 to spend, intake and flowmasters or magnaflow?
