I have seen a few people out here who have a custom built exhaust. I have the Tanabe and eventually will be looking at the Mazurri Headers. I was wondering if I can do anything on my own, with a custom exhaust shop with everything in between the headers and axle-back exhaust. i.e. what can I do with the mid-pipe section and how??
thanks.

 

Something minor & quick would be to remove the secondary cats or remove the oem resonator on the OEM piping

The gains will be minimal and sound will increase slightly as well...

 

i just removed my sec. cats and i want the exhaust to sound louder than it is...do you know any1 who did the cats and remove the resonator and how would that sound??

 

It's been discussed to great length here

 

I cut out the resonator. I have the Tanabe......sounds alot better
