I have a Megan racing y pipe and Tanabe Medallion axle back, the sound was good on these two components but then I tried test pipes and it was very raspy. Then I tried CNT Racing Resonated Test Pipes, the rasp is a little less but it is still there. Any idea on a replacement of the catalytic converters which would have no rasp.

 

resonated HFCP.....Test pipes will almost always make a VQ hoarse

 

Throwing on a resonated HFC on mismatching exhaust diameter components is definitely a shot in the dark. And a expensive shot in the dark.

 

Are they both not 2.5''? I was assuming..

 

from what i understand, any hfc setup will have rasp. resonated or not.

 

Nah, they're different.

Nope, too many variables to consider.

 

The resonated test pipes are 2.5 of CNT Racing, the Megan Racing Y pipe is 2.5, the mid pipe is stock and the Tanabe axleback is also 2.5
The Y pipe and axleback sounded good but wasn't loud enough, the test pipes does make it loud but raspy too.
Was thinking if there is an option of making it loud and not raspy

 

Your best bet here is probably getting a better pair of resonators swapped in place of your stock ones. There are a few videos floating around of a member who used kinetix hfc along with vibrant resonators and a Tanabe axleback and it sounded exactly like what you're going for.

 

Motordyne LTH





Motordyne E370 catback.<br/><br/>Exhaust could be tucked up better but no other complaints, no drone. I always get complements.<br/>I believe I should be the one and only sedan with the headers according to Tony back in may.<br/>

 

That must sound amazing. Sure are some sexy exhaust components.

 

I need someone to drive my car so I can hear it lol

 

Were these made just for the your sedan? I think I've spoke with one person off the G37/370z facebook page that said Tony made a a sedan specific header for him. So you'd be the 2nd? I'd love to own a set one day also.

To add clearance to the infamously low Motordyne muffler, loosen the bolts on the Y pipe, get a jack underneath the mid muffler and slowly jack it up right until the flanges hit the subframe. Then, torque down the Y pipe, you will gain a few inches of clearance and it makes a big difference.

I'm curious to see how your car will sound like Calg37USMC, I have a good feeling it'll be close to mine. It seems most aftermarket header to E370 setups sound similar. I heard a local 370z and G37 sedan that had Stillen/PPE headers to E370 . That was honestly the biggest reason I got a set of aftermarket headers, the lower RPM range exhaust tone with headers changes.

 

Ughhhhh that looks amazing. I can't wait until my E370 is built and on a delivery truck. Only 20 more days! But who's counting?!

 

lol i want to hear your car too
