slick Posted August 12, 2009 Report Share Posted August 12, 2009 Tons of people have. What are you trying to ask? Quote Link to comment Share on other sites More sharing options...
RobertISaar Posted August 12, 2009 Report Share Posted August 12, 2009 LOTS of people. and it will make the exhaust a hell of a lot louder. sometimes i think the cat does a better job muffling the exhaust than the actual mufflers... Quote Link to comment Share on other sites More sharing options...
CutSupreme93 Posted August 12, 2009 Author Report Share Posted August 12, 2009 what size pipe and everything i need to do this, i figured more then a few have done this, whats the best way to go about it? Quote Link to comment Share on other sites More sharing options...
RobertISaar Posted August 12, 2009 Report Share Posted August 12, 2009 i think the inlets and outlets of the cat are different sizes? if so, you'll need to just remove the cat using a saw-zall or something similar, then get the correct amount of pipe to replace it, possibly with adaptors to adjust for the size difference(if there is any). also, get the clamps, because if your exhaust is rusted to shit, welding won't be as effective.

19Cutlass94 Posted August 13, 2009 Report Share Posted August 13, 2009 It should be 2.25" pipe Quote Link to comment Share on other sites More sharing options...
CutSupreme93 Posted August 30, 2009 Author Report Share Posted August 30, 2009 cut the cat out today and have decided its a little bit to loud, will a longer or better quality resonator quiet it down any? (the pipe i replaced it with was one of the $5 resonator pipes at autozone) Quote Link to comment Share on other sites More sharing options...
tunerlover3 Posted August 30, 2009 Report Share Posted August 30, 2009 A used a cherry bomb glasspack in place of my car and my car is still louder then hell lol Straight pipe FTW!!!! Why did you cut your cat off? Quote Link to comment Share on other sites More sharing options...
CutSupreme93 Posted August 30, 2009 Author Report Share Posted August 30, 2009 it was clogged up im just wondering if i can get rid of some of the noise under the cabin, i knew the exhaust was gonna get alot louder but didnt know the majority of the loudness was gonna be under the cabin.

tunerlover3 Posted August 30, 2009 Report Share Posted August 30, 2009 Then im guessing you have an exhaust leak. What kind of exhaust are you running? Is it stock with the cat delete? Quote Link to comment Share on other sites More sharing options...
CutSupreme93 Posted August 30, 2009 Author Report Share Posted August 30, 2009 yeah its just the stock system with the cat delete for for, do you mean like a gap in the pipe i put in? Quote Link to comment Share on other sites More sharing options...
tunerlover3 Posted August 30, 2009 Report Share Posted August 30, 2009 Yes the exhaust must not be sealed if you are getting a lot of cabin noise. Just deleting your cat wont make it super ass loud. Quote Link to comment Share on other sites More sharing options...
CutSupreme93 Posted August 30, 2009 Author Report Share Posted August 30, 2009 thanks i bought some sealer from autozone im gonna do everything tomorrow and hopefully everything works out fine. thanks for the help Quote Link to comment Share on other sites More sharing options...

CutSupreme93 Posted August 30, 2009 Author Report Share Posted August 30, 2009 no its like a putty that is suppost to harden after it cures Quote Link to comment Share on other sites More sharing options...

CutSupreme93 Posted August 30, 2009 Author Report Share Posted August 30, 2009 what would you suggest using? Quote Link to comment Share on other sites More sharing options...
tunerlover3 Posted August 30, 2009 Report Share Posted August 30, 2009 The right exhaust pipes lol Or get it welded. Quote Link to comment Share on other sites More sharing options...
RobertISaar Posted August 30, 2009 Report Share Posted August 30, 2009 get it welded. right idea, probably a tough execution though. if the exhaust is rusted to hell, and it probably is, you HAVE to clean a good portion of it off for the weld to last. that putty is basically a high-temp JB Weld.

CutSupreme93 Posted August 30, 2009 Author Report Share Posted August 30, 2009 ill probably just use the putty for now and when i goto get the flowmasters installed i'll have them weld a pipe in. Quote Link to comment Share on other sites More sharing options...

tornado_735 Posted August 31, 2009 Report Share Posted August 31, 2009 Would cutting the cat out of a '94 GP mess with the computer at all? This is something I have considered doing. Quote Link to comment Share on other sites More sharing options...
