Header install only?
Has anyone performed this upgrade-just headers no main cats but kept the rest of the exhaust stock.
It seems to me that most of the gains are from headers since the oem units get pinched down badly at the collector.

I did that on my 97 base model and could really hear and feel the difference, however when I did the same thing on my 04 S I could not feel anything. go figure. I would however suggest at least putting a KN air filter in along with the headers. both would help.
the muffler is mainly for sound improvement, and weight loss, and some power , that is if you are unhappy with the original P sound

Thanks, already have the cold air induction unit. Did your header install remove the large cats attached to the stock header? How many labor Hrs. did it take?
I will keep everything else stock.
Thanks Rich

Make sure you spray liquid wrench or pb blaster on your head bolts before removing them or else there's a good chance you'll be breaking them off. I replaced all of mine with grade 10.9's from mcmaster-carr. And make sure to coat them up with antiseeze when you reinstall them. And you can get pretty much the same Chinese headers on ebay for around $100. $250 is a little pricey.

+1 on what budman says on the bolts.
Also, if you change just the headers and yours is an '00 or newer, you will throws CELs because you've eliminated the set of cats that are measured by the O2 sensors. You will need to relocate the O2 sensors.

" intermediate pipes and I guess I will be getting rid of my Borla mufflers and make a set with 2" inlets, as of now I am still running the 1 3/4 " pipes from the collector on back- on another note I found Borla had inserted a venturi in their inlet that reduced the 1 3/4 " to about 1 " so I removed them and it goes quicker now and louder.

I just saw the 49.00 earlier this evening I dont know what you have but Im guessing they are all the same. I got them ceramic coated to attempt to reduce some engine bay temp so far so good.

The headers will radiate less heat if you use a silver coating. Flat black is the worst color you can paint them... though you might see some benefit as a thermal barrier if they were coated on the inside as well.
