LT Headers & no cat question? I have a 98 SS camaro & I was planning on installing a set of hooker LT headers & Y-pipe with simulators but I have a guy telling me it wont run worth a crap without cat converters..will blow black smoke out & could cost maybe as much as $1200.00 to make it right.
I would think it would run ok without them & maybe redo computer at a later date sometimes if needed..Whats everyone else doing that is running LT headers with no cats?
Hes an exhaust man that thinks he is a professional tuner or something sounds like to me.
Please let me know some opinions
Thanks,Brian

Re: LT Headers & no cat question? I second that. I have 42,000 miles of Hooker Coated LT's and ORY. No oil burning or smoke. Keep in mind that the cats do soak up a little crap emmited from the exhaust but it's not any thing to cause damage to your car. Everybody has an opinion, respect it but don't listen to it.

Re: LT Headers & no cat question? I too have Hooker LT's and ORy-pipe. It runs a little richer since there are no cats, but other than that it's fine. I haven't had any problems just like everyone else posted.

Re: LT Headers & no cat question? Thats absolutely not true! I too run Hooker LTs, and never a problem. If the car runs a little rich with them, put a ported maf on there to lean it out, or get a MAFT. You'll be fine! ...Just don't listen to tards like that. <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

Re: LT Headers & no cat question? I run SLP LT's and off road pipes w/simms and have zero problems. Like was previously stated it seems a lil' rich at the lower RPM's. But the only problem may be pesky cops who don't like the rumble... <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" /> Hope this helps.

Re: LT Headers & no cat question? Thanks guys..looks good to have so many positive votes on this..I didnt think it would be a problem but wanted to check first..
Jrz28>>What do you mean tunned in? What did you do?
Mobe>>Im gonna port MAF for sure & I also think that will help with any rich conditions to help lean it out a lil more..
I think everything will be fine..again thanks!!

Re: LT Headers & no cat question? All the cats do is decrease emissions of certain gases. Removing them will not cause the car to "run bad". That is just <img border="0" alt="[bullshit]" title="" src="graemlins/gr_bs.gif" />
It might not give you a huge power gain to remove them with stock internals, but with things like a cam or H/C or more, you'll notice nice gains <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

Re: LT Headers & no cat question? I have SLP LT's with ORY and no cats with LM. Mine runs fine. No black smoke -- just dirty quad CME tips after a week and a half of driving.
