i am about to replace my stock cat converter and thinking about getting a hi flow cat. but what do i do about the o2 sensor since there is no hole for it? can it be drilled to fit an o2 sensor or do i have to condemn it?

 

A shop can add an O2 bung, but why go with a HFC rather than a new stock replacement or a used OEM one?

BTW, IIRC if you have a HFC and a stock y-pipe, your CEL will turn on.

 

curious of why there is no CEL with aftermarket y-pipe and HFC together.

 

I believe Warpspeed Performance and Cattman offer highflow cats, if I'm incorrect I'm sure somebody will correct me. You can check for yourself , I'm sure about Warpspeed having them but not a 100% about Cattman.

 

>>Call Brain catts at cattman..520-575-6195...he has Random Tech cats...or do a poormans hi flow,,take the stock cat off take a broom handel and knock out all the platinum honeycomb Bam hi-flow cat..

 

Isn't test pipe better?

 

i just need a new cat man...bad. the one on my car is shot...when i step on the gas i get this really bad stench from my tailpipe...which is also broke. im gonna buy a new obx muffler of ebay.

 

Yea just delete the cat with a test pipe man then you won't have to worry about it. I have the same stench but mine smells all inside the car because of stupid precats that's why I have headers on the way

 

oh yeah...my cel is already on because of that cat converter...i gotta replace my y pipe too. but i just got a job so i'll try to get a new one soon....not a warpspeed though...those make the car sound ugly.

 

A lot of Warpspeed hater's here, they don't sound bad at all if you set them up w/right combination as with any exhaust setup. Get what yah like though.

 

yeah imma do it right the first time...save up some cash and go cattman!!

 

Test Pipe = BUZZING...I had a cel for my cat..I took it off gutted it ,cleared the codes and No more cel... Its when a cat starts getting gummed up with carbon when it tosses a CEL.NO guts no clogs..It worked for years on my 5th gen untill i killed the car..Il be doing my 4th gen this week...and cattman headers and y-pipe are the best combo.Brains headers are not shortys like the ebay stuff they are a lil longer and sound much more tuned then others..

 

my cat converter is toast man...its rusted, the o2 sensor popped out of it one day when i floored it...it smells too when i accelerate hard.

 

Being in south Tx i never even think of rust...yep you have no choice but to replace it...Thats crazy how the O2 popped out.... LOL

 

you guys in texas are lucky...this is a minnesota car so u kno rust is a big thing. i just looked at my broken pipe at the back and it broke right at the flange.

 

i know what your talking about.... my car came from texas in 03 and 7 years later.... ouch. rusty gatonby!! lol! thats why i bought warpspeeds entire kit. y-pipe, high flow and cat back for just about $600 cause im a cheap bastid.. but it doesnt sound terrible. i guess ive just grown accustomed to it.

 

so i bought a fireball muffler off ebay...now i need a new cat. im taking chrisman287's advice and just get a new or used oem replacement. does anyone have one in good condition that i can buy from them for cheap? i get paid end of the week...not much money but i really need one asap.

 

Jus get the direct flow magnaflow cat off ebay. Wdnt mess wit the universal fit. It wd still work but is gonna be more work to install.

Test pipe isnt worth the CEL issues. IMO

 

I got my Bosal replacement cat off eBay for a good price. It's an OE style that bolted up perfectly. There's a waranty on it as well and I believe it's stainless steel (flanges aren't).

 

Random Technology has a direct cat fit too.

 

Just changed b pipe and muffler(oem), thinking about warpspeed y pipe and cat,(more on the price and mpg than power) how big trouble for the state inspection? I am in New Jersey.

 

sooo, yor gonna replace the headers instead od the y-pipe??? hmmmmmmmm, FAIL!!! you will yeild a much bigger gain from a new y-pipe the new headers, plus, you get a nice 15-20 hp boost!!!

 

cattman is expensive and the guy who answered the phone was tellin me 800.00 for a cattback, 400.00 for a cat. friggin ridiculous!!!

 

yeaaah man I picked up a catback exhaust on the b/s/t forums here for $120 now its time for ebay headers ypipe and hiflow cat! or i was thinking warpspeed hiflow cat and ypipe + ebay headers hmmm

 

$800 for a catback exhaust...holy cow!!!! who in the hell's gonna buy that??? that's way over the top. wonder how much is the cattman y pipe and headers for a 96?

 

Yeah Mann, that's what da Fucck I've been sayin'!! Warpspeed offer's an excellent cat for much less or just go factory Mann!! Cattman's shiit is good but just way over priced mann, get what you'll be happy w/though. If I was a billionaire I'd get the best for whatever the fuuckin' cost but since I'm not, I get the best for the best fuuckin' price.

 

That stench is because of the eliminated cat. Eliminating the precats in the OEM Y areant going to get rid of it.



People buy them all the time, an average good quality catback costs around 600-650 so its not that insanely priced considering.
The headers from cattman cosst more then their Y pipes. Its either one or the other.

 

Custom Catbacks run about 300-400, 2.5 SS with Muffler and custom tip. Thats what I went with.

 

Wow headers come with y-pipe way to make yourself look like an idiot plus its the long collectors headers have that gain the most hp. the only FAIL!!! is you

 

my cat isn't eliminated

 

My apologies, I thought you were running a test pipe and were soon to eliminate the Y pipe precats.

 

800 bucks is wayyyyy to much to pay for exhaust on a 13 yr old car. how long u plan on keepin it\???maybe another 3-5 yrs. Ebay or WS exhaust will last that long and its 100s cheaper.




ANd one more thing....FAIL ....I jus wanted to be down lol

 

600 for a greddy. I consider that to be top of the line. I dont think cattman that much better for extra 200. I mean, its ONLY an exhaust kit

 

I agree about a cheaper exhaust lasting long enough to make one happy, some just wish to have the best items out there and are willing to pay for it.
Greddy is a good exhaust system but I wouldnt put it on the same level as the Cattman. Many have had some fitment issues with the Greddy, as did I when I had one and I have yet to see someone say that about the Cattman.
I personally wouldnt pay that much for an exhaust system, it is just an exhaust system and the gains just arent there.
My 3" setup cost well below what an aftermarket name brand exhaust cost.

 

Oh no, but soon I will eliminate the precats and then throw in a test pipe

 

u can ge full exhaust header back on ebay for less than 500 shipped thats headers y pipe cat and catback if u wanna save some cash

 

Yea but none of it will fit right and its terrible quality.

 

I paid around $425 for a 2.5in SS, mandrel bent catback w/ Magnaflow straight through muffler.

 

i no a few guys with this setup and they all said it bolted rightup noprobs and they sound just as good as my car and i have greddy catback and warp y pipe and ebay headers

 

I wdnt go so far to say terrible and i wdnt say it wont fit right either. Every mod requires some modifcation.
