G35TOIS350

^^ ive pretty much accepted the fact that no car will sound like my G coupe did that was the best sounding V6 ive ever heard. nissan/infiniti worked very very hard in designing that exhaust to sound like that. it was one of their main goals with the car.

it probably would sound a lot better if the stock system had a better location of the flanges for an exhaust. The only flange on the system to bolt on to is after the resonator, most aftermarket exhausts replace the resonator because there is a flange before this which is after the cats. But that isnt the case on the IS. If the resonator is replaced it would sound and flow a lot better and have better gains.

Unless you want to do some cutting welding and fabricating a custom resonator.

what if you take the resonator out completly and put the Tanabe on?

you know i just thought about that comment for 5 minutes. it could sound pretty damn good! it could sound like a freaking lawnmower too.

i come from the thought that the exhaust should compliment the engine. meaning it shouldn't just be a loud sound, but a souund that if closely listened to, could distinguish between firings. this comes out in a sound-of-sex with ferrari, and the devil released through exhaust on american muscle.

Thank you for explaining how the exhaust system is laid out on the IS. I really need a picture of the underside. Still thinking to wait and see what other exhausts come out.

probably loud and raspy

heres some pics of the stock exhaust:





the piece on the bottom the dual cylinders are the cats, then following the resonator and youll see the flange which connects to the top set of exhausts. No flanges after the cat =

exhaust manu's need to learn that this car needs catback systems...and i mean from the first set of cats

our car has 2 sets...2 right after the header, 2 right befor the res...i believe

Do the 250 and 350 exhausts compatible?

Ya. the G does sound very nice. I guess I'll wait and see if there any other better sounding ones that come out later.

yea but there are no flanges to do a true bolt on connection. Most aftermarket manafacturers like to go bolt ons for simplicity. Also if someday the car would have to return to stock it wont be a pain to put the stock exhaust back in if you did cutting and welding

I was originally looking at the LMS but to be honest I didn't like the idea of getting rid of my cats. Not only for warranty but installation being a pain in the a$$ also. I think i'll be happy with this

If I'm not mistaken, the dual cylinders are not the cats. The cats are further upstream right behind the engine. Cats will always have bungs to plug the 02 sensors in. I think this is more of a dual resonator cat back.

from most other car exhuast systems Ive seen, those 2 cylinders seem to
be the cats. and the one big cylinder seems to be the resonator, i bet it'd sound
nice if some1 just replaced that resonator with a straight pipe, not to mention probably a 5-8 hp gain, and even if it didn't sound that good,It wouldnt be that hard to cut and weld it back on..

Funny that this thread is not even about dogs? Yet the first dog is way cooler

Question. after installing the Tanabe exhaust is it still just as loose and wobbly as the stock exhsut? The stock exhaust is soooo lose and bounces all over the place on when the road. and especially over freeway lines.
