garagemethods Posted February 9, 2009 Report Share Posted February 9, 2009 so right now i'm running headers and no muffler off a 3 inch head pipe. i'd like to get a straight tube to bolt in place of the cat so i'm running full straight pipes. but... i've read that with dumps or straights like that your fuel can become too lean? so what's this about? would i gain from straight pipes or would i run too lean and actually loose power?

1 Fast SS Posted February 10, 2009 Report Share Posted February 10, 2009 Damn, that's got to be loud. You might get a loss of power code unless your tuner turns it off. I don't see any power gains from it though. Quote Link to comment Share on other sites More sharing options...
garagemethods Posted February 10, 2009 Author Report Share Posted February 10, 2009 so why would there be no power gains? and also when i delete the cat how do i by pass that o2sensor? Quote Link to comment Share on other sites More sharing options...
70chevy03ss Posted February 10, 2009 Report Share Posted February 10, 2009 you got to get your pcm tuned for the cat delete. Quote Link to comment Share on other sites More sharing options...
garagemethods Posted February 10, 2009 Author Report Share Posted February 10, 2009 straight pipes.... gain or loose? from my understanding its actually both... you get a sluggish launch but more top end. and that once tuned for the straight pipes that you loose that slugg launch? finalize this for me please. and sorry i keep posting about all this deleted cat and straight pipe crap. just keep thinking of new stuff to ask and wanna get it right before i do it.

NashSS Posted February 10, 2009 Report Share Posted February 10, 2009 If you wanna dump the cats then I say go for it but you will definatly want something. Go with some flowmaster Hushpowers or a SLP Loudmouth II's if your looking for something slim but if not then I say go for some magnaflows or borlas. Borlas sound really good imo with some headers and no cats. Everyone is into there own thing so just search around on youtube or streetfire and look up sound clips of what your wanting to do to get a general idea of what you want.
