Header install?

[Aleks]

Where should I go to get my header installed? Also should I bother getting an aftermarket cat or should I just stick with the stock one. I already have a catback exhaust.

Thanks

When it come to your cat, it al depends on your stock manifold. Some of the Altima had the cat right up front, instead of undernite the car. If that's the case which I don't think it is. You can stick with the stock cat.

I have a cat under the car after the downpipe. My car is a 93 so it's a OBDI.

Unlimited Performance does that...they did mine and i dont have any complains...but now when i was taking out my engine and i took off the headers and i realized how easy it was i wasn't very happy...if you are a do it yourselfer or on a limited budged then i say do some of the work yourself...Remove the stock exhaust manifold and put in the headers....then take it to any exhaust shop and get them to cut the exhaust piping so it connects with the headers and weld/screw it all together where they join...that should save you tons of money

ask someone here to do it for you - its too expensive to do in the muffler shops for something so menial.
