exhaust systems - 5/12/2007 10:28:19 PM    EvilZombieZ   Posts: 281 Joined: 11/11/2005 Status: offline I hear if your car is NA that a 2.0inch exhaust is better for low end torque, smaller exhaust = low end torque, is that correct? Also if I go 2inch exhaust pipe with 3 inch muffler into a 4 inch tip will that be louder then a 2.5>3inch muffler>4 inch tip? Post #: 1

RE: exhaust systems - 5/12/2007 10:37:33 PM    yevgenievich DodgeForum Moderator Posts: 408 Joined: 2/15/2007 Status: offline smaller exhaust means more backpressure and small backpressure helps at small rpm's. I think going from small to big makes it louder, so going from 2 to 3 to 4 should be louder than starting off with 2.5. Personally i think there wouldn't be much diffrence. Also i think 3 inch tip looks better than 4 inch, i looked at some 4 inch tips and they looked too big to me. _____________________________ (in reply to EvilZombieZ) Post #: 2

RE: exhaust systems - 5/12/2007 11:10:29 PM    yevgenievich DodgeForum Moderator Posts: 408 Joined: 2/15/2007 Status: offline i would do 2.5 " with some headers. If the headers and downpipe stay the same there is no need to go above 2". On drag strip you drive at higher rpm's so bigger is better. at higher rpm's the engine trying to push huge amount of air out; so small exhaust is restricting. On small rpm's small exhaust is just right becuase there is not as much air going out and everything runs fine. When having a big exhaust at low rpm's engine is pushing the air out and it have hard time because there is a lot of area to push the air tru. Try blowing air tru a small straw and big straw to see the difference and then deside what you want. I drive  under 2000 rpm range so i put empty cats and 20" glasspacks for some backpressure instead of muffler. Having tru duals i did noticed more power at high rpms than before because there is less restriction. hope that helps _____________________________ (in reply to EvilZombieZ) Post #: 4

RE: exhaust systems - 5/13/2007 11:52:55 PM    EvilZombieZ   Posts: 281 Joined: 11/11/2005 Status: offline my exhaust is single, personally I love custom exhaust. a lot cheaper and it will be just as good as a $800 borla. I just got a straight pipe all the way back. (in reply to streetstealth) Post #: 8

I think stealth sounds real nice with stock exhaust with empty cat and no muffler. _____________________________ (in reply to EvilZombieZ) Post #: 9

RE: exhaust systems - 5/14/2007 10:47:21 PM    EvilZombieZ   Posts: 281 Joined: 11/11/2005 Status: offline any muffler shop should do a custom exhaust. but they may not take out the cat converters as they are illegal, so you may need to find some small privately owned garage to do it.
