how is it that a stock cat is way more expensive then the ones u guys mentioned?

 

Too expensive for my high school needs.

 

I was wondering that too. But I definitely don't want a stock one.

 

Find a good local exhaust shop that has a mandrel bender.

 

Then what?

 

have them install whatever it is that you buy perhaps?

magnaflow is not expensive compared to the other cats mentioned in this thread.

this is just for example I dont know what the cherokee's pipe diameter is off hand. Just showing you that you can get name brand stuff in your price range.

 

Do yourself a favor and go to Rustysoffroad.com and they have a package deal for under $250 (atleast they had that price when i ordered mine) that includes cold air intake (with K/N filter) throttle body spacer and a choice of any flowmaster muffler you want you also get 2 1/2inch catback....This is what i ran on my old xj and it sounded great just have the muffler shop take the cat out (if you dont have inspections)......

 

Cherrybombs are like $20 at the auto parts store. I like mine but which I had upgraded the whole exhaust to 2.25 or 2.5inch as 2 inch seems a bit small for a 4.0L engine.

 

I bought a TB spacer for my last Cherokee and researched it afterward (backwards I know) The conclusion was that they are $75 paperweights that look neat. I noticed no difference in performance.

I also had the K&N drop in filter, no difference. However, I have never ran a cold air intake on a Jeep, just Hondas.

I have inquired about high performance cats and hear they dont perform much differently than a regular cat.

I would save the money on a high flow cat and put it towards a Flowmaster muffler. I ran that and 2.25 piping and it sounded nasty! Do it right the first time and you wont be dissapointed. Flowmasters FTW.

 

Ehh i didnt really want the spacer but it came with it so i said w/e and threw it on anyways lol......

 

Anyone have sound clips? I am very particular.

 

Wow, cheaper than I thought for Magnaflow. What kind of sound will that give?

 

Check out U-tube.

 

X2.....


Or if you want to wait until tomm. or so ill post a vid of mine........

 

I think I might want to get a cat back system. I have heard a lot of good things about 2.5" diameter pipes. I don't know much about exhaust.

Would it be cheaper for me to piece together my own? I am sorry if my questions seem redundant, I am just having a real hard time figuring out what I want. And since I don't know much, it is extremely difficult.

How would I go about getting 2.5" pipes and would that require a lot of work?

Once again, sorry for the redundancy of my questions.
