Stillen exhaust or straight pipe?
 

I currently have the Stillen exhaust on my car now. Before I had it completely put on, I cranked the car without the muffler and loved the sound, but couldn't justify spending that much money on an exhaust and not put the muffler on too. So, what are the pros and cons of getting rid of the muffler and straight piping over the Stillen? (I plan on removing the Stillen exhaust and using the stock exhaust for the straight piping). Power loss/gain? Sound? (I know straight pipe will be louder, but is the sound that much better?) Any thoughts and information would be greatly appreciated!

you'll lose HP on a N.A. car due to back pressure loss if you run straight pipes.

dont quote me on this, but im pretty sure this is what happens.

Even if you run the exhaust all the way out the back? I don't mean cut off the exhaust mid way under the car...I'm basically talking like a muffler delete with it straight piped out the back.

bluz34 has the muffler delete done to his car. his car went from 297whp to 307whp with the muffler delete and fujita intakes. so im guessing it doesn't really lose power. as for hte sound, it has a very nice tone but gets really loud at WOT.

correct, like delusional said, bluz34 did this and saw decent results, however i still believe the gains are just from the stock exhaust sucking so much.

for instance i have the ark, if i were to negate the X pipe and turn it into straight pipes, i would lose power.
