it has borla exhaust and some k&n short air whoever had my car before my had one cat removed and there is no 02 sensor on that side
i was also wondering if these headers were any good http://cgi.ebay.com/ebaymotors/98-02-CHEVY-LS1-FIREBIRD-5-7L-SS-V8-STAINLESS-HEADER-01_W0QQcmdZViewItemQQ_trkparmsZ65Q3a12Q7c66Q3a2Q7c 39Q3a1Q7c72Q3a2125Q7c293Q3a1Q7c294Q3a50QQ_trksidZp 3286Q2ec0Q2em14QQhashZitem35a1ffbbc5QQitemZ2303511 58213QQptZMotorsQ5fCarQ5fTruckQ5fPartsQ5fAccessori es

im wondering what mods i can do my self that will gain the most hp and how much work is it to install the headers someone told u u have to drop the motor

well as far as those headers i would not buy them there cheap and most likely will not fit properly. You dont need to drop the motor, if you dont have much mechanical expirience dont do it your self. I would spend the money on some coated brand name headers you will save your self a major head ache. i would also look into taking that other cat off. And good luck trying to find a good shop to do the job most places dont want to touch them because there a pain in the ass.

i say gears are probably your best bet has "bang for your bucks" goes

Fix the one sided cat issue first. If you don't have an SES light then you either have a tune or some O2 sims.

What K&N do you have? The FIPK or just a drop in filter in the stock air lid?

There are some ebay headers that are decent, but I'm not sure if it is those. there are also some that the collector hits the floorboard. Do a search on ls1tech and you'll get all sorts of info on them. Fit and finish would be what I'd look for. No, you don't have to drop the engine to put on headers. Don't listen to who ever told you that because they don't know what they're talking about.

You can do all the free mods and bolt ons yourself with a little mechanical knowlege and some hand tools.

Honestly, your best bang for the buck will be suspension and tires. If you can't put down the power that is already there, what will more do for you?

i have flow tech lt's and i had to heat the pipes just before the colector and bend them a little to get them to fit. also i should have listened to everyone who told me to start with tires gears and suspension. because after all the money i put into it i lost a second off my quater time because i cant keep the tires from spinning.

thanks for all the help ill use all the info and i have the FIPK k&n i got a set if eibach springs for the car havnt installed them yet tires are kohmo 275/40zr17s its about time to replace them though any thoughts on tires this is a daily driver

after all the money i put into it i lost a second off my quater time because i cant keep the tires from spinning.
and i thought i was alone! lmao. id say a dr, even for a dd. nitto555r's are probably what ill get next. maybe mt's, but theyre a bit stickier(which is a good and bad thing---10 bolt :( ) and wear faster from what ive heard.

Rethink the Eibachs. Especially if they're Sportlines.

I've been daily driving on Nitto555r for the past 1.5 years. They call them drag radials, but don't really act like it IMO. They're more of a semi soft street tire. The only Kumho street tire I'd consider running would be the MX.

Choosing a tire depends on many things like budget, climate, and usage. Poke around on tirerack and discounttiredirect and read the reviews.

ya any future money is being saved for the replacement of the weak 10 bolt for a 12 or 9 inch im not sure yet. also rear suspension. ohh yea and some fat DR'S

Poke around on tirerack and discounttiredirect and read the reviews.
ya, tire rack is AWESOME for reviews and great prices. just make sure you read up and know about wear rates and how they affect how well itll hook. thats where i messed up when i ordered lol, so i got a tire that wont hook, but itll last forever.
