my converters are shot; I need something to stop the choking.



I'm considering either the racing beat header/presilencer combo ($300) or the cat replacement pipe ($110).



Racing Beat claims the straight pipe offers about 2/3rds of the increase of the header/presilencer.



Anyone want to weigh their opinions?

I think with stock ports, a straight pipe is adequate and accounts for most of the power gain. A healthy port job and you will need a header.

actually even with the stock ports you get a significant raise in power from the headers. the stock exhaust manifold ( if you want to call it that ) is very inefficient. if your gonna do the straight pipe just invest a little bit more and get the whole header and piping done.

on a streetported 13b what should be better,streetable header or race road header?

of course rb parts.

also what muffler do you insist me?

ok when you put the header, presilencer and the cat replacement pipe on, do you need to change your stock muffler? and does anyone know if that is all emissions legal in TX?

if you buy a compatible header/presilencer combo, it should connect to your muffler with no problem. However a good after-market muffler will make a noticable improvement in horsepower, as well a nice exhaust note.

The Rotary performance cat replacement pipe will also connect to your muffler.

I bought a cat replacemnt pipe from them for my '90 N/A. Just so you know, it definately improved the sound and made a little more power, but for the price I think it was of questionable quality...Looked like some dude in high school metal-tech class put it together. Just my 2 cents.
