I'm looking for the exhaust with the deepest note. I don't care so much how loud or not loud - mainly I just want a VERY DEEP/LOW exhaust note worthy of a big v8 so no one will mistake my car for a ricer Any suggestions?

 

Assuming your driving the GS4/430 i would say HKS Hipers, or you can take the route I did at one point and convert a Greddy Evo2 catback into straight duals- that was definitely a damn rumble!

 

Thanks - yes I've got a gs430.

 

Greddy Evo is pretty loud.....HKS is subtle.

 

Yeah, I was making reference more so to the deep low note than overall loudness. My Greddy Evo2 is louder than what my HKS was but I wouldn't say by that much...

 

this is going to be one very hard question to ask, i don't think anyone can tell you what's the deepest sound one for sure, a lot of us just hear couple of them and there are other factors like intake, etc...

i have heard hks, very deep sound. i have also heard tanabe and that's pretty deep too

 

JIC Bullet Spartan, but be prepared to pay $$$$, read a review, think it was on overboost. They did an install on a GS400. Called it the "Gentlemen's Mustang". If you go to the sitcky for exhaust sound clips, somewhere near the end of the norcal clip you'll see an SC400 with it. Sounds awesome, and MUCH deeper than any others.
