tdvs Posted September 22, 2008 Report Share Posted September 22, 2008 Wish I'd have known all this 2 months ago Could have saved over $200 on a new cat and O2 sensor Could have gotten a couple of door dings removed instead with money left over Tom Quote Link to comment Share on other sites More sharing options...

AWeb80 Posted September 23, 2008 Report Share Posted September 23, 2008 on a 95, no 96 and later yes...unless you have a O2 sim. Quote Link to comment Share on other sites More sharing options...
pontiacmaniac94 Posted September 23, 2008 Report Share Posted September 23, 2008 on a 95, no 96 and later yes...unless you have a O2 sim. the o2 sensor on the 95 and older cars are placed prior to the cat, so you will be gold, no codes, no running rouugh, no nothin. OBDI FTW! Quote Link to comment Share on other sites More sharing options...
swift13 Posted September 23, 2008 Author Report Share Posted September 23, 2008 i dont think so i have replaced the o2 recently seemed simple enough except for the location and i know i keep kind of asking the same questions over and over but i wanna get this right. i am assuming the back pressure changes so does that effect the performance at all(for worse) or is that just if it gets clogged??

tdvs Posted September 23, 2008 Report Share Posted September 23, 2008 not much...my GP is NICE now after the cat is off. Actually sounds better with it off or just stinks? smells great....and sounds great Hope this isn't too far off topic. But speaking of sounding great, I live a block and a half from Fox Lake and am sitting here with the patio door open listening to a high power, high speed boat going by with open exhaust.....MAN....I love that sound....Music to my ears Wish my CS vert sounded like that to people off in the distance Tom Quote Link to comment Share on other sites More sharing options...

88red4cyl Posted September 23, 2008 Report Share Posted September 23, 2008 Not trying to hijack your thread here, but I have a question. (mods, feel free to move this into its own thread if you feel necessary).. I am wanting to replace my cat on the LTZ with a straight pipe... How do you go about this? Is any welding required (I.E. I have to take it to a shop), or does the old one unbolt and the straight pipe bolts back in? Quote Link to comment Share on other sites More sharing options...

If you find a speed shop, they might...or you may be lucky and they'll do it and write it off as "off-road use only." Quote Link to comment Share on other sites More sharing options...
swift13 Posted September 23, 2008 Author Report Share Posted September 23, 2008 i have used clamps and they did not leak but i also said a weld would be stronger and more secure even if it does leak a clamp can still be used its not like the car is going to blow up.
