PO removed the cat when he installed "unknown" new muffler..

whats a good cat you could recommend??

anyone have the part number for the sensor?? I'll be needing one of those also

 

The hanger that is welded before the cat (one right above the cross member) broke off my exhaust, how should I go about fixing this so that the exhaust stops hitting the cross member when I am driving?

 

Take it to an exhaust shop. They'll fix it.

 

hey, i had trouble finding the answer to my question so here goes, i am putting a new motor in and want to get upgraded headers and all new everything all the way back.

my question is, what do i do with the two small cats that were on the far end of the headers and the O2 sensors that belong to them. do i have to replace those cats or can i cut them out of the system?

and either way what brands are preferred for headers and cat. i think i want flowmaster 44 or 40 not sure yet.

thanks a bunch

 

There are a few brands that make the two piece headers. Those precats are required by federal law

 

^Clifford's dual-outlet headers look really nice.

 

I need to ad a CAT BACK or just muffler to my 95 XJ . I will read all of this later , but right now I an looking at a JEGS and Mega or Magna flow on Amazon.com. I would like to stay under $150.00 and I dont want a real LOUD set up, just something that sounds good and might give some more POWER.Any ideas out there????

 

Look at performance curve they have a nice deal for the xj.

 

+1, I did a 2.5" cat back with a hi-flow spun cat and FM40 from them, very happy with the price and quality.

 

Thanks MY89XJ, They have a sweet deal that I am going to go for $105.00 . What is the XLERATOR perpormace??? I could not find specs on that. I saw a FLOWMASTER , but they are way to loud. So I think it will be the magna flow cat back for $105.00 . I am on a budget now so this is a sweet deal THANKsssss

 

Xlerator is a knock off magnaflow

 

Okay I'll ask again...

I have no cat, a new muffler and pipe (unknown brand) but without cat it sounds healthy to say the least...

with that...

what cat would you recommend?? I also need the sensor, good online source??

yeah I could read/search even more threads but since this is a sticky here it goes...

advice??

 

Flowmaster 50 is quite.
Thunderbolt cat with an o2 bung hole

 

Don't forget the performance curve discount code if not too late. 5% discount code "CHEROKEEFORUM"
