Any 1998-2000 GS3 GUys with Header and Y Pipe? What are you using?

The OBX/Turboeast Y pipes are too short for the 1998-2000 GS300. But will fit the 01+ perfectly

Before I get the obx/turboeast Y pipe extended, what other alternatives are out there that will fit?

MELGS300

That's a great question. I didn't know they even made headers for a 1998-2000 GS300. I would like to try to get my hands on a set. Do you know where I can purchase one? Hopefully not on ebay. Don't trust too many items that come up on ebay!

wow i didnt know that the y pipe in the 98-00 to 01-05 were different lengths

mikal

well, some auctions on ebay said Y pipe will only fit 01+ GS.

When LMS installed my header, the Y pipe didnt fit my car (1999)

I think i'll just do custom Y pipe.

I have the OBX headers and yes the y-pipe is too short. This is because the header is for the IS 300 but fits the GS. I'm using the stock y-pipe, it bolts right up to it. I was trying to sell the OBX Y-pipe to some IS or 01 GS guys.

Lexism do you think you received the same performance mods with using the stock y-pipe? I'm thinking about doing the same mod to my 99 gs300. Was it hard to modify the OBX header with the stock Y-pipe or simply a bolt on swap?

I'm sure I get a little less performance, but not by much. I really was concerned with the car being too loud. As for the headers, it was a clean swap. No modifying the stock y-pipe at all.

thanks lexizm

lexism how do the headers sound and do you feel the performance gain?

mikal

I'm still using my stock exhaust and the Header is not loud at all, Even with my supercharger.

Regarding the how the car sounds with the headers, I get a lot (madd) complements on how my car sounds... finally...and not just from Lexus owners. It's not too loud for me at all, remember, I have a Carson Tune exhaust from the cats back. It sounds rugged at WOT.

Oh, almost forgot. Yes, I deinitely feel the difference in performance. I just have to keep remembering to reset my ecu.

Do you know what the hp gains are? Can you feel the hp gains?

mikal

well, I cant really answer that since i got it installed with my supercharger which gained about 125-135 rwhp.

Update, LMS extended the Y pipe for me and installed it the other day.

All i can say is... it's a must have. Freed up some backpressure. My car accelerates alot smoother and quicker. But still a bit restrictive due to my stock center pipe and stock exhaust.

Exhaust noise is still the same as before.
The Y pipe installation elimated the last CAT.
No More hesitation while coming to 1st psi of boost (had a problem with my stock y pipe which i guess was a clogged cat)


I'm pretty happy that they extended it for me
