racing beat is hands down the best exhaust. dont buy anything else. i have racing beat headers, pre-silencer, y-pipie, and mufflers and it is the most amazing sound ive ever heard. plus i actually feel the difference in hp gain.

 

i don't get what we're proving for you...

 

thats one of the most rediculous statements ive ever heard! sure racing beat is a nice exhaust, but there are several manufacturers out there with quality exhausts.......greddy, hks, ssautochrome, apex'i, etc........ concidering the very little horsepower gain you recieve on an na application, its all about what kind of sound do you wanna get out of your exhaust...... in my opinion, the best bang for the buck exhaust system out there is ssautochromes.... ive heard nothing but good about their stainless exhaust, and you cant beat $450! racing beats is almost double that!

 

well if you wanna go custom....... id go w/ a 2 1/2"-2 3/4" piping..and a quality muffler...dont buy a cheap $30 ebay muffler..they cant withstand the heat a rotary puts out! you'll have the guts of that muffler hangin from your tailpipe in no time!

 

yeah if he had an extra $450 then why not, what i did was get a $100 muffler from the local ricer shop, got racing beats headers, and got a shop to do a custom 2.5 inch straight all the way from the headers to the muffler, sounds strong....and loud, but unforgiving in high RPM.
