What does everyone think of putting an exhaust cut-out on? My brother has an extra one from his car cuz it was too small so I'm most likely going to put it on. Do you think having it open will free up some hp and do better in the race?
:roll: Umm no.andystepper said:hey..nice to see another saskatchewan member. and no. our cars need back pressure to run properly. a cut-out with only make things worse.
These cars do NOT need backpressure, they need exhaust velocity. A cut-out should be just fine, although unless you have a restrictive exhaust system its doubtful you'll see much of a gain.andystepper said:hey..nice to see another saskatchewan member. and no. our cars need back pressure to run properly. a cut-out with only make things worse.
Your engine needs to have a specific amount of back pressure to operate at the optimal performance. I dont understand why you would want to cut a hole in your exhaust, it will only make it sound like shit and run worse... :-?skunkworks_zed said:These cars do NOT need backpressure, they need exhaust velocity.

the crappy manifolds take care of the exhaust velocity.. it will gain overall flow and top end power but at the cost of low end torque.1991z24 said:Your engine needs to have a specific amount of back pressure to operate at the optimal performance.

actually you'r setup creates more back pressure than u would think! (bends in pipe :wink: ) and all a cutout unless you'r engine is highly modded will do is make a big loud noise, give you'r car less power, and make alot of people laugh at the track!! (louder dosen't always mean more power)blondiez24 said:I took out my cat, and put 2 1/4 inch mandrel bent pipe from the downpipe back, and a straight through muffler its an apexi n1. I prolly don't have much backpressure. As soon as I left the exhaust shop I could tell a major diiference in power. The throttle response was greater, and top end is alot better. I would say an exhaust cutout would prolly help you out more than my setup.
idk my car had a little more balls open headers but maybe it was a mind thingscott0999 said:turbo cars can benefit from it. n/a doesnt as much. thats about it
i guess all the N/A drag cars have cut outs for show eh? :lol:scott0999 said:turbo cars can benefit from it. n/a doesnt as much. thats about it
The difference is that his is turbo and your's is notskeezix said:This will be completely free because my brother bought it for his turbo shadow but it was too small so he just made one him self but took it off and runs no exhaust and hasn't had any problems at all.
