I have a friend that has a SRT-4. If u remove the exhaust system from the downpipe back you would get a big HP gain. I will soon be purchasing an Evo 9 MR and was wondering how this performs on the EVO.

Also i would like to welcome my self to the EVOm forums. Best Forum hands down!

 

It might perform well but it will spit soot all over the undercarrige of your car and real loud

 

will sound like ***...do that if you're going to the track...not for daily driving...

it's an evo...not a rental ...i mean srt4 ...

 

But what about performance gains? Is it going to kill HP or increase it?

 

That would be *LOUD*. As in... you would have to kill the motor any time a cop was within earshot.

 

I live in a Hick Town. Where evey one has the huge Turbo Desiel trucks. Sound is not a problem in my town. not a problem. i just know the [ SRT-4 hate to compare ] gained 1 second with the exhaust removal. just wondering if anyone has tryed this on the EVO?

 

people do it...

...temporarily! It will get annoying after awhile...there are other ways to get power without resorting to making your evo sound like a 2$ civic

 

Sounds good, thanks for the info

 

really, it doesnt sound bad, i removed mine for about 3hours, untill i couldnt stand the pain any longer. everything rattles inside

 

There is no way in hell you gain a full second in the 1/4 by just taking off your muffler.

 

Muffler to DP

 

Still, the amount of HP needed to drop your et by 1 second is not going to happen by running straight off the DP.

 

i agree. i used to own an srt4 and that is impossible!!!!

 

Add a 3" TBE and electric dump pipe.

 

I have a rmr downpipe and my stock cat. i have the dump open everyday, its no louder then a diesel. somtimes i drive 2 hours straight and it dont bother me.
