I was considering exhaust cutouts. Im thinking about the Mr. Gasket cutout with the cable for remote operation. I'd really prefer straight pipes but cant afford to get any tickets at the time. I was just curious if i mount them right in front of the catalitic converters, will the complete lack of back pressure cause problems or not? i have heard that some back pressure is needed, but id like other opinions. I can get the cutouts for $40 from Jegs. I know a guy with a muffler shop that can install them pretty much free. </P>


Im just wondering what everybody else thinks.</P>

Backpressure..I hate that word!

No, backpressure is NOT needed at all. In fact, it's one of your worst enemies.

 

Alright they are going to be ordered tonight. Now i'll be able to blow those ricers off the road without even being in gear j/k. From what i've read, up to 15% hp increase is possible from stock, but i doubt it will be that much w/out headers. </P>

yeah...apparently its "exhaust velocity" thats necessary (as i saw in an argument that the jeepster had or something).

 

A friend of mine put a single exhaust cut-out before his cat, he had edelbrock headers...he dyno'd an extra 22RWHP & 8RWTQ with the cut-out open.

 

Think about it....everything you do to this air pump known as a motor revolves around getting air in and out faster and more effeciently.

Backpressure is just what it sounds like, the exhaust being restricted and causing the motor to be "choked". How can this possibly be helpful?

Kyle, I'd have the dumps welded right after the cats (so E-check can't rag on ya), or if you wanna play it risky, before the cats. It'll be like open headers.

 

Hey thanks everybody.</P>


Dan02gt, that gain is awesome, I dont have headers now but i 'd be happy with anything close to that.</P>


Jeep, ya, im not sure where im going to put them yet. I know the people who do the e-check around here are normally dumbasses who couldnt care less if the car passed or fails. i think about it.</P>

For the money, if you can deal with the noise.....it's the BEST bang for the buck mod available. I did the math with my friends HP gain and it was alittle over $1.30 per HP...awesome deal if you ask me! Hahaha

 

why not save up for some long tubes and then just leave them where they can be uncaped easy? instead of spending 40 now spend a little more later and really blow those ricers away&gt;<IMG src=smileys/smiley4.gif border="0">

 

Buzzstang...i would love to get longtubes, but being in highschool, money isnt that easy to come by. I plan on getting headers in maybe a year or so, but for now, the cutouts are the best i can do.
