Hi gyus
Have order JUNTW full exhaust from Headers to Mufflers.
After a lot of searching thought to be the best choice for IS250.
Should be in my hands end of this week and installed next one.
I'll do some posting with the results.
Hope made a good choice and see some gains.!!!!!!!

 

im about to be a new IS owner and also new to this site. I would like to say that this is one of the best threads i have ever read. it is perfect for those that are in the market and can find all infos on one page. keep this up!! this site is by far one of the best car sites ive been on. VERY GOOD STUFF!!

Thanks

 

um dude... the megan exhaust u posted is wrong as far as the burt tips thats the MEGAN OE-RS cat back.. it is different then the cheaper megan axle back exhaust u posted in the you tube clip...

 

can someone update the exhausts. the f-sport, joe z, greddy have come out now. updated info ftw.

 

If you send me (pm them to me) factual information regarding those exhaust mentioned in basically the same format as above i can add them.

I do need to update this original thread some.

 

Came across these headers, but the manufacturer's claims are pretty steep. Any thoughts?

I have them on my ride.
They deliver what they claim for.
The craftmanship is superb and fitting as stock.
Only problem was with the Cats that gave me a CEL all the time after 120 MPH and had to buy new ones with better quality.
Manufacturer didn't accept any liability and said that they should work fine with the O2 extenders that came along but that wasn't the case.
If you want them take them without the cats and put youself a pair of quality ones.
There is a thread that i've shown pictures and dyno charts before and after.

 

Feel free to use my sound clips on YouTube.. http://www.youtube.com/user/ricedout...25/O3q28oOtxnI

Updates please. How bout intakes.

 

Ya where are the intake comparisons?

 

they say that HKS-hi power will actally lose power...this guy lost 15hp with intake..when he added the hks,and k&n

 

Mods. It's almost been 3 years since an update. Can we get something more final started. Jw?
