5Zigen!!!!!

5 Zig!

 

Fireball


Boba- who says that the Apexi is the loudest exhuast......GOODBYE!

 

Ok, a bit off topic but what a good place to buy one. Where are the deals.

 

apex n1 is very loud. why not try a greddy evo??

 

Neither...they're both N1 style mufflers.

Get a Thermal (Stealth).

 

Here's a question...do the any of these vibrate...producing that rattling noise?

YellowDragon... do you have dyno charts?

Dyno charts of what?? The Thermal?

IMO you only need an axle-back system (unless you're making some SERIOUS power upwards of 200 whp).

Expect to gain 5 hp tops with an exhaust. Mostly you'll achieve this on the top end.

 

Here's a thought...what if I get the exhaust...then the rest(piping) later. Is that possible? Will companies sell just the piping? What does the Thermal Stealth run?

 

I would suggest just purchasing the axle-back (muffler and connection for flange). A number of diff companies offer this (Thermal included). If you want it to be more quiet, get the *stealth* version. I'm sure Thermal would sell the rest of the piping later, but I wouldn't get it for the ITR. There are minimal bends in the factory ITR piping...

I just read the title of the thread and my immediate response was, "NOT the Type R!"

 

I only gained .3 whp removing the axle back.... and 4 whp removing All but the header...
