Im looking for some recommendations on a high flow cat for my 04 sunfire, and i was wondering if anybody makes one thats a direct bolt-on for my car?

check out the Magnaflow website. I can't remember the part number but there is one a lot of people are using from them. Use the search feature on this website, you may find what you want.

thats exactly what i needed to see, now for the important question how much louder does it make your car and/or does it free up any horsepower as well?

are you replacing anything bt the cat? if not, then there's no point unless your current one is clogged.

run 2.25 pipe from the header to the cat, put a LARGE resonator (thrush glasspack), more 2.25 pipe, and a muffler of your choice. best sound, best gains, no rasp.

not a bad idea, but how do you think it would work out with a vibrant cat back exhaust? b/c i was also thinking of getting that
Re: high flow cat

well my opinion would be that you could put in ur aftermarket cat and the vibrant cat back, but you may find it too loud/raspy so you might have to chop it up and toss in a nice big resonator just after the cat.

ummm, catco makes direct fit cats for the j's I have not checked to see if they had one out for the eco's yet, but they do make them for 2200, 2.2, & 2.4?

comes with an o2 bung already welded on. and so long as you have a resonator and muffler you're golden. no load at 55 in 5th, you cant hear my car. as soon as i open the taps though, it lets you know its not stock. no rasp.

pacesetter ceramic header - thunderbolt ceramic cat - thrush glasspack - mandrel stainless 2.25 - dynomax superturbo - cheap chrome slant cut resonated tip. i may try to get a sound clip tomorrow.

take a look? if there's a sensor after the cat, then yeah. MOST cars made after 96 had the post cat sensor. there are a few exceptions, but just look. cant miss it.

cant miss it if you look at the cat from the drivers side. dont have to jack the car up even, just look at your cat. if there's a sensor there, then yeah, ye need the sensor.
