Hey guys I have a stock 2010 Evo X and today I installed a straight pipe instead of a muffler. Sounds great but when im getting on it at about 6k rpms pulling hard it makes a studder like its hitting fuel cut of or somthing just for a split second then gets write back into it! Does anyone know why this might be happening

Thanks

 

is it tuned?

 

^^ what he said. i have an 08 and did the exact same thing as you and have had no problems. i've been rolling like this for a couple years now.

 

nuh its not tuned

i wanted a cheap way of having a good sound of the car

would it be safe to drive the car like this with out a tune

 

Is it safe to have your car run crappy?

 

Just out of curiosity, how loud is the car no it is sans muffler? I have personally never cared for the sound of any car, even a performance type car with just a straight pipe. They sound too truckish for me.

 

if you still running the factory cat your fine

 

lol +1 for a home made exhaust

 

That's too funny

 

Your most likely over-boosting from your lack of restriction in your exhaust, Do you have a CEL (CHECK ENGINE LIGHT) on? If not, try to replicate the problem twice in a row, then see if the engine light comes on. In order for the Overboost CEL to illuminate it has to happen twice within one engine cycle (key on to key off)

 

I ran with a TP, factory midpipe and muffler delete. Sounded great
