Currently I run a zpi stage 1 with full zpi exhaust and s pipe.
I hate the look of the zpi axleback. I want to change it to the megan oe rs axleback (looks like the trd), this will attract less attention from the police. it is a 2.25 exhaust
Now the dilemma is it will not perform like my zpi axleback. I was contemplating doing the exhaust cut out. Now if i tune my car with the exhaust cutout, and use the 2.5 s pipe to 2.5 midpipe to 2.25 muffler for daily driving, how rich would that put my car?
Would it put it rich enough to a point where its damaging my car or will it be slightly rich and tolerable for daily driving? I really want an exhaust that is not going to get me pulled over just because of the looks of it, but i am not seeing any 2.5 mufflers (besides the dezod but thats 630 bucks as a kit). Can i get some opinions on this issue?

 

bump for some info, c'mon i know some of you guys know the answer to my question..

 

why don't you just run a boost activated cut-out? www.atpturbo.com

 

its more expensive the the electric one, but an interesting concept.

 

I wouldnt do a boost cut out. He say he doesnt want cops on him about his exhaust. That will open anytime he hits boost.



On my brother car he runs 11.4 wot with the cutout closed and 11.4 wot with it open. NO need for tuning ours. Unless you plan on running it on the downpipe or something then it shouldnt effect anything since all the o2 sensors are before the cutout.

 

with an open pipe i will be boosting higher then with a closed pipe, it will definitely need retuning

 

yea im gonna do the same thing too after i put my turbo kit on, im gonna get the electric cut out and for exhaust im gonna use the greddy evo 2.

 

any of you know the size of the dc sports exhaust axleback for the tc? i need a 2.5 pipe axleback

 

Check out your other posting. I put the type of exhaust up you should get.

 

60mm aka 2.25"
