Catted or Non-Catted Prochamber

[ScrmngYellow04]

I have the MAC 2.5" catback currently.

Which Prochamber?

Catted
Non-Catted

Thanks.

That depends if you emissions test in your area. If you have to go in for emissions testing, get cats. If you don't, get the catless and you'll have to turn off the o2 sensors in the tune.

I dont think I would have much trouble getting it switched out once a year to pass emissions.

Hopefully if no one looks under the car it will pass the OBDII test with no problem.

Anyone had any success with getting inspected with no cats?

Ok someone else vote or comment please.

Thanks.

No cats sounds much better. But ask yourself are you commited to changing back and forth from stock H pipe to pass emmissions every two years.

Do you need cats in your area?? Down here we don't have checks anymore so o/r midpipes are pretty much the norm.....if you don't have checks I'd run an O/R. If you do have inspections then it's up to you....You can either run the o/r and just swap it back come inspection time and hope nobody gives you hell about it or just lose a few Hp and spend a little more $$ to run a catted pipe....

Hint: They probably won't look under your car if you pass the obdII test with no problem.

Catted, I dont think you will gain much power without cats, and it will smell much worse. Just my opinion.

Just had the Mac O/R ProChamber installed this morning... sound is awesome with the MagnaFlow CatBack. STOP... about the same, noticed no difference in performance, and no smell what so ever.... just my .02

 

[Dan_Soprano]

I'm considering the Catted Prochamber myself......the stock mid pipe with a magnaflow catback just isn't cutting it anymore!

Well I ordered the O/R this afternoon and the MIL eliminators.

Will I need the 02 extenders?

Hopefully not.

Cant wait to get it installed and hear how it sounds.

If you have a 04' I think you will need to get the extenders..

Where did you guys buy your catted prochambers from?

 

[pvteye]

yes.. had to have extenders for my 04, could have made it easier to have extenders for the front O2 sensors also... uncatted the sound i awesome
