I have a automatic 2001 gle i was looking to get a Cattman Catback Exhaust System, I was wondering if I would evem notice a difference, if so how much thanks

 

Not a hell of a lot. You need to add more bolt ons then that. Try intake - headers - and catback. Then yes, big difference.

 

get the y-pipe

 

headers and 17* timing advance FTMFW!!!

 

the only horsepower related mods i have are the cattman catback and a k&n drop in. i noticed increases at higher rpms, and no real difference in gas mileage (initially your mileage will go down because you might rev it up more to hear how cool it sounds)

 

intake and catback almost do nothing for our cars... The reason that most of us have it done is just for the sound that we want to hear. For your year one of the best gains you can get is a Y-pipe, or if you want just a little more you could swing for some headers

 

Might as well just do headers instead of y-pipe.

 

im kinda strapped for cash what about the cattman cat back exhaust, air intake, and test pipe?

 

what is a good y pipe and how much do they run?

 

Ive sceen em from 100-300+ depending on the brand and who is selling it, just go look in the forsale section, i bought mine yesterday, it was the topspeed auto y-pipe, ive heard its a cattman knockoff for 140 shipped. Ive heard good things about cattman. Go look on ebay and the forsale section of the forum, you might find you a good deal.

If you go headers go w/ the long headers like the ones cattman makes, its been proven that the shortie headers give little if any gains at all.

I doubt the cat back will give you any real #'s but it shure will make your car sound faster and give you that

 

get headers, you'll get 20 hp.

cat back will give you around 4-5 hp (most of that comes from the b-pipe)

 

keep your cat.. there are really no gains from losing it, and it just makes your car smell

 

ya but it sounds better without

 

ok so does anyone have an estimate in tenths of a second what these mods will do on a 01 maxima gle automatic? Stillen Y Pipe, (Removing Cat. replace with Test Pipe), Cattman Catback exhaust system, cold air intake. Thanks

 

All of that will gain you jack sh*t for HP and will cost more than headers. Get a set of Hotshot headers for $500, have them slightly modified to fit the 01 and call it a day.
