so i have a cel it is P0420 and it is the catalyst but i have just replaced both of my o2 sensors and now whenever i am driving and go into vtec my car sounds like it is in vtec but doesnt feel like it, it goes into vtec but doesnt give the jolt of power like it should and i dont know what it could be please any help?

 

Are you sure its not time for a new catalytic converter?

 

that might be the case, would that make my vtec quit working? if so what type of catalytic converter would everyone recommend?

 

if you cat is so backed up with crap, then yeah, you don't have any power.

look up carsound

 

what about this obx high flow?

wrong, all wrong, no

Do like the man said and look up carsound. Way cheaper than that POS and much higher quality. Best source for carsound cats = eBay.

 

hold on so i did and whenever i do it comes up with magnaflow or some car audio stuff, so please help me because it bugs the crap out of me and plus that one that i found you have to have it welded is there one that is bolt up

 

if i have to get that one that has to be welded what size inlet and outlet do i need

 

carsound is made by magnaflow, so yeah

and as for getting it welded, what kind of exhaust do you have?

 

just stock

 

im not a big fan of loud obnoxious exhausts and havent found one i like

 

what about this one????

https://www.tonnocover.com/applicati...stomer_reviews

 

that one is a "Option: Direct Fit Catalytic Converter- 49 State Legal "

 

so is that good or bad?

 

i mean will it work or what?

 

I believe stock exhaust size is 2.25"....if so, here's basically what you want:

Obviously, it can be found on eBay:

If you get this unit, you will need the muffler shop to weld in an O2 bung (cheaper than buying the unit that already has it). As for flanges, they aren't required. However, if you want them, you can cut them off the old cat or purchase new ones.

 

Looks good, except I don't see an O2 port. Pretty cheap and already has flanges. If it has the port, you could do the work yourself in 5 minutes.

 

well if i actually go to that website and put in my year and model etc. then it tells me that my exhuast is only a 2 inch but thank you and you would recommend just going with one on ebay and that is that brand and just having it put on and have the O2 bung put in

 

The 2.0" model number is 94004. However, the direct fit you posted might be your best option. Depends on the cost of flanges and how much your muffler shop wants to charge you.

 

thanks i think that is what i am going to do for sure
