Ive got a 99 ex witha CEL Code 67 and am wondering what route i should take. im looking at getting a pacesetter high flow unit or should i just source an oem replacement. will the high flow negativly affect my mpg? and as for noise im not worried i have a greddt tic catback and live in AZ so the cops could giva ****

thanx

 

any mods done to the vehicle besides exhaust?
id prob just stick with an oem one.
unless you plan on turboing it or swapping the motor or something

 

none just iridiums and a K&N filter from the previous owner the only other things i plan for the engine are CAI new plug wires thats about it i like the mileage and reliability as its my DD for now

 

im almost positive that u can run an aftermarket cat without any negative affects. i kno u get more power.

 

^ yeah like .5 hp lol just gut your existing cat it will probably help out your mpgs see as there might been lots of carbon build up in there

 

Gutting the cat actually decreases performance as the gasses get caught up in the empty can..just replace it with a new cat and done deal.
Hi-flow cats a bunch of either stick with stock or get a test pipe.

+1. Hi-flow cat's on an engine that hasn't been built or turbo'ed is freakin pointless. If anything, get an ITR exaust system so it at least SOUNDS good.

 

So passing emissions and still reducing restriction is pointless?

I'm not saying it's the most cost-effective thing to do, but I wouldn't call it pointless...

 

just do whatever is cheaper..
im sure u could find a hi flow cat on the marketplace for fairly cheap

 

find a used 02 to for the oem.hi-flow and test pipes are basically the same thing.its better then the oem restrictive cat.

"With a difference of only 1hp between a straight pipe and a 49-state LEGAL cat, it seems foolish to flaunt the law and pollute the air that we all breathe. Hell, if you are only looking for those kinds of gains, just loose 10 pounds -that alone will make your car faster than adding 1 measly HP."

Straight quote from Import Tuner. So go with an OEM. At least you can use that argument against them if they try to start some ****.

 

oem cat = $500

magnaflow cat = $70 + installation

 

true im not looking to gain anything from this insatall i just dont feel the need to fork over an insane amount of money to a dealer for a pipe with a filter in it when i could get an after market piece that flows equally as well or better for much cheaper that wont negatively affect the drivability or mpg

 

well in that case i think you'e answered your own question..

 

true true thanks HT

 

Fo Sho. ^^

I found that article in a random google search.

I'm not trying to say OEM cats are junk, just that it's not worth it to use a straight pipe to gain power. A high flow cat will gain you some power while keeping your car legal to drive in these great United States.

 

thanks for posting that article i didnt see it the first time through it was exactly waht i was looking for
