how do i hallow my cat? does it make a diffence and does it make your car alot louder??

 

Just get a high flow cat....or a test pipe. You might need that cat. just in case you don't pass emissions

 

we dont have emission test anymore... at least in minnesota- and i dont have nice exuast so i want to know how to hallow mine out so i dont have to spend $90 on a high flow cat. because i'll probly get header-back exaust eventually


96 preludeS
aem cai
zex wet 55 shot

 

will a high flow cat make a noticeable difference in performance?

 

Not really, you rarely get a noticeable difference from any one mod.

 

basically if you're gonna do exhaust and want to notice the gains, do it all at one time, header, cat and catback, and you'll notice some gains, and if you have a crappy exhaust, don't waste any more money than you already have with your crappy exhaust, save the money you were gonna use for that cat and get a good exhaust, i.e. greddy, mugen, thermal

 

it doesnt get that much louder...before this b16 civic kept pulling me top end, after i gutted the cat he didnt pull me as hard...

 

what do you mean? you kept up better with it gutted?

and how much would it cost to repair that turbonetics your selling?

 

just undo you exhaust and take a bar and ram it through the cat, clean out the pieces

 

it wont make my car backfire or anything crappy?

 

well if your o2 sensor is after the cat it could make it run lean.

 

don't hollow out your cat. it'll sound like a raspy high pitched civic. you'll not feel any significant power gains.

 

you can notice a difference in power depending on the condition of your factory cat. When we first put the f-max kit on my brother's car, the car ran alright, but not too impressive. He dyno'ed it and the numbers came up pretty low. Got a custom exhaust setup from RollHard (using their muffler w/race tube option.. which by chance his car is on their website!) and a random tech high-flow cat. Gained around 40 hp at the wheels. The block on his OEM cat was all clogged up and could have actually been melted together from the hot exhaust gases getting trapped in there.

 

Breakdown w/90 bucks and get a Carsound or Random Tech cat...

 

i have a random cat for a 4th gen if you want it...1 month old....$150

 

if your state doesnt have those crappy emission **** crap, just go to a muffler shop and have them weld you a test pipe, you can sell the stock cat and make some cash out of it. especailly all the cali guy is getting them from ebay because back in 95' they hallow their cat out. lol
