hey guys. im new to the forum. and i read about 19psi wanting to do his exhaust. just warning u, i have a 90 ls and i did sumthing similar. (big...big mistake what i did). i got a custom exhaust done and had the 3(center) cat deleted, deleted the resonators and mufflers. did 2 1/2 inch true dual inch piping and just put a couple of strait pipe mufflers and the sound is amazing. such a low and nice pitched sound but actually slowed my car down.i lost so much backpressure, its not even funny. now im desprate for backpressure. yeah my high end is a lil better. but my low end is crap! im getting my exhaust redone as soon as i get more money :-/. any recomendations? im for sure getting rid of the strait pipes. i need anything that will give me backpressure.

this thread has gone off topic:
i found this as a source for jdm body kits ,toms exhaust , and a coilover kit all are pricey.
http://lexusparts.stores.yahoo.net/adgsgs.html
also found this for chrome grill of the 90-94 ls400 cheaper body kits also:
http://search.store.yahoo.com/cgi-bi...ms&query=ls400
found exactly what i was looking for here :
this seems to be a one stop shop for the eairly LS400
again pricey but its a lexus , they even have headers :
http://www.l-tunedparts.com/model/st...id=2&cat_id=10
now where else can i find a catback exhaust for my first gen LS400 or have they all been discontinued by now ?

ask some of the vendors, i think highsocietyvip had a discount on bodykits and maybe exhaust, pm MrMark. but u should just fab ur own exhaust, it'll sound better and you can just find the tips.

I saw the question asked, but I didn't see this issue resolved. I can't find a Borla exhaust for my car (90 LS400). Did I miss something? What other exhausts would you guys recommend from the ones available for my car?

What are you expecting out of the exhaust build? I don't think you would be unhappy with just about anything. Are you looking for a particular sound or look??

I just want a little sound. I still want the car to stay relatively quiet at cruise speeds with no drone. A little sound at idle would be OK, but I just want it to sound good when I get into it. Obviously, I'd like some performance gain too, but I've been in the car scene enough to know not to expect much from a catback. About how much power do these cars typically gain with a catback, high flow filter or intake, and whatever other basic bolt-ons that I could find (any help in finding other mods would be appreciated 
). I've also seen a few posts talking about the "air box mod", could someone elaborate or point me to a thread on that.
Sorry for all the freakin n00b questions!

i bought some lowering springs that were 2" lower, but it wasn't nearly low enough for the vip look i was after, so while i'm saving for coilovers, i cut another 1.5 coils off the lowering springs for a 4" drop. the springs were made by some custom shop in california, i found them on ebay for $75 brand new. they were very comfortable but didn't look good enough for me with the wheels i have.

LOTC, is that your blue LS400 or is that some pic you found on the net? btw, do you know a good site to find body kits and also some carbon fiber hoods? (mostly for lightening purposes)
