Hello everyone, I just bought the K&N short ram air intake for my 2008 IS 250 awd and am looking into getting an exhaust. I was thinking about the Tenabe Medalion Touring cat-back system.

Wanted to know what you all think and if this will generate noticeable HP or if the exhaust would be annoyingly loud, as i would like to be able to continue using the bluetooth speaker phone affectively and also have a nice exhaust.

 

None of the intakes really produce big gains, maybe 5hp with JoeZ or F-sport. Depending on exhaust you may see a little more but really most mods are just for sound from what I've read here

PPE headers may be a good choice though. Some decent and proven gains there, 16hp or so.

 

you might get 10whp out of the PPE headers on the 250. Those cars are just NOT ever going to be fast.

 

tanabe medallion axleback you mean? it's so quiet, i had the combination...the intake was nice but switched it out for a takeda (pretty much same sound and loudness but i wanted the dry filter and i sold the k&n at a very good price), and soon replacing the tanabe with a greddy evo3 because it's just way too quiet for my taste..i think stock g37 is louder than the tanabe lol

if you have a 250, mod for aesthetics sound and handling, forget power

 

Just a heads up, the Tanabe is an axle back, not a catback.

You will get ~5-7hp out of an axle back. But you wont get any noticable power out of any bolt on mod for our cars so just go for sound.

HKS is the loudest followed by the Evo3

 

is that so evo3 even louder than fsport?
i actually don't want it that loud

 

I thought it was?

Didnt someone do a comparison? Just based on sound clips, the Evo3 sounds louder.

The Fsport is quiet IMO

 

dang...we'll see once i get it
i think a member said it was a little louder than joe z...but never heard joe z in person

 

Me neither. I think all exhausts are quiet honestly.

Even with an invidia midpipe, my HKS sounds quiet to me

Edit: Actually I should change that to not loud enough for me lol
