just louder. race or test pipe itll just be louder as there will be more flow. unfortunately i dont have any videos anymore of my stock with res and cat gone. also better lope. and depending on the muffler (no no muffler) more pops (at least mine does and a few ive heard do)
HEY CORKSPORT!!! I see you have a catted racepipe for the mazda3. I have your catback exhaust but did not get the racepipe because then i'd be catless and would not pass TEXAS inspection.. How hard is it to include a cat in the racepipe for the mazda2? My understanding is that the mazda2 has 2 cats, one eliminated with the catback exhaust, but the other remained and i was able to pass inspection. Am i right about this?

i went straight pipe cuz the guy told me the unmonitored car was basically a resonator. since most places dont sniff and im not throwing codes i believe ill pass but i wont know till late next year.
I kinda want the CorkSport race pipe too, but not quite sure why. lol
Cat back seemed like a huge improvement, so if the race pipe adds even part of that on top of... then I guess that's why... but not sure of legality/smog differences over 2nd cat.

I know for sure it will at least be somewhat louder, but because it's a secondary cat being removed and there will still be a cat in place, I doubt it will be raspy like a catless setup. I was hoping someone with the corksport/race pipe setup would chime in. I was also considering just having a muffler shop fab one up, but wanted to get some details about the corksport piece since there isn't much info about it on the site.

well it increases the velocity of the gas since the pipe will be smaller thus making it slightly raspier on the top end. im not sure what our high flow cat looks like but when i was helping some speeds change downpipes to high flow ones the high flow is just high the size of the regular cat and alot smaller in diameter for more gas flow. i do know on mazdas the more you take off the deeper it gets in the low and the higher it gets in the high. its weird. not like hondas where its either really deep bass all the way or really raspy rattle tin all the way.

When did you send the email in?
The difference in sound level is not too much, maybe 1-2 db at most. Installation of the racepipe will not trigger a CEL since the first catalyst off the header is the monitored cat. Since it does remove a catalyst there is some legality concerns with it for some people and states. The clip we have posted up is with the racepipe installed.

I'm in Dallas and my MSP was catless for the 6 years that I had it. I passed every year. As long as you aren't throwing a code, you'll pass with no problems.
This from TX DMV...
1. Inspection Procedure. Examine visually.
2. Inspect for and reject if:
a. The exhaust emission system has been removed.
b. The exhaust emission system has been disconnected.
c. The plumbing or hoses are loose, broken, leaking, or improperly routed.
d. Air pump (air injection-type) belt is loose, removed, excessively cracked, frayed or has pieces missing.
e. The exhaust emission system has been altered in any manner to make it ineffective.
f. The catalytic converter has been removed, leaking, or disconnected on a 1984 or later model vehicle.
So....... I guess as long as it all looks ok... i thought they did a "sniffer" test but it looks like thats only on older vehicles. Everything else seems to done by the OBDII port. so no codes and if it looks like no cracks.. leaks.. seems like it would be ok.. hmm. what are the gains of the race pipe? Now i'm torn between lowering the 2, getting the racepipe, or getting the ecu tuned. UGGGGHHH!!!

OK not sure why I didn't just call in the 1st place, but I did get the details I wanted about the pipe. Its just a simple 2.125" pipe with a flange to mate up to the manifold/cat and a flared end to properly connect with the front end of the "catback" pipe. No resonator. Stainless steel.

like i said (and this is from a muffler shop so who knows if they are right lol) the guy said the 2nd unmonitored car its basically a resonator. most places dont sniff anymore since technology in cars basically examines everything if youre not throwing codes then youre ok.
honestly....i may put a fake heatshield on my exhaust to make it look like i have a car or something....just to play it safe.

the CS just replaces the 2nd cat and resonator with just a resonator. we cant alter the monitored cat as it is in the downpipe of the exhaust manifold. youd have to buy new headers/exhaust manifold or get a new downpipe.
i think you mean the secondary cat.

The monitored cat is built I to the exhaust manifold and won't be altered by a catback/race pipe setup. Inspection will be determined by the inspection station since you technically removed an emissions device.
