Icon10 MAGNAFLOW cat & exhaust system

I have a 2000 prelude & I am wanting to put a MAGNAFLOW catalytic converter. I need to know what is the diff. between a hi-flow converter with no o2 sensors that is universal & one that is specifically designed with o2 sensors, which is better? I also want to dual it out using a MAGNAFLOW muffler. Again which MAGNAFLOW is best?

Re: MAGNAFLOW cat & exhaust system

its always better to get the one with o2 sensors because if your 02 senser is not connected, the check engine light will come on.

Oh and, IMO, dual exhaust on a 4 cylinder, FTL

Re: MAGNAFLOW cat & exhaust system

IMO is In My Opinion and FTL is For The Loss. Dual exhaust looks bad IMO as well.

Re: MAGNAFLOW cat & exhaust system

Doesn't dual exhaust on a 4 cylinder kill HP?

Re: MAGNAFLOW cat & exhaust system

i wonder if dual will help out in a boosted way..but thats a whole different topic.

whatever youd like to do to your car is your choice, but were trying to advise you with dual exhaust you actually hurt performance

I believe so yes, unless you're turbo'd or have a really high compression ratio.

Re: MAGNAFLOW cat & exhaust system

Even with turbo I would not dual out the exhaust, I would however go with 3" piping all the way back.

Just for kicks, I am trying to find a stock exhaust I really only need the axle back (muffler)

My thread

Anyhow if anyone has the old stock muffler lying around might be a little cash in it for you.

Re: MAGNAFLOW cat & exhaust system

i remember magnaflow is having problems with there o2 sensor, even though its new it might still throw a code i believe they are working on that problem. about the dual exhaust, wouldnt hat kill the ludes torque? with so little torque already i wouldnt get a dual exhaust but thats my opinion.

Re: MAGNAFLOW cat & exhaust system

i just swapped over from a test pipe to magnaflow high flow cat and i still throw a code but its not the bad cat code. its like sensor bank 1 blah blah blah. and get the one thats vehicle specific. it bolts right into place and you dont have to have flanges welded on or add O2 bungs. i like saying that. bungs.

I just saw 2 Caliber R/T's with dual exhaust & they are 4 cyl. Besides I think it will look different & good. I want to stay away from the coffee can look anyways.

What single turbo kit is good & what twin turbo kit is good?

Re: MAGNAFLOW cat & exhaust system

Yeah I will just that 1st things 1st: got a full body kit & a re-paint job on the car that I am waiting on. The body shop is taking their time ( which I am fine with, got to fix the driveway so that I don't scratch it ) they also took out all the dents & dings! got new halo headlights, new taillights. When I get the car back all the tags are expiered. Catalytic needs to be replaced. I talked to a mechanic that said if I do the exhaust @ the same time it would be cheaper! So I am going with a single muffler & dual it out from there.

Re: MAGNAFLOW cat & exhaust system

I have the magnaflow too and love it, you can usually get a used one on ebay or cragislist. I wanted a valid warranty so I got it here. Magnaflow 21009. Also some of the forum sponsors selling magnaflow usually have a sale going on. Either way its a great cat, sounds great, and very easy to install.
