AW header + zpi s-pipe = loud rasp but i dont mind.

its been talked about using header wrap or thermo wrap

i wrapped the runner closest to the alternator (to protect it from heat)

and wrap in between the runners and where they all met up to the bottom flange.

sry no pictures, will post tomorrow.



conclusion
failed
but there is LESS rasp though :D

 

resonators man.

 

^^ what he said.

the instigator put a 30' magnaflow resonator on his AW header, CC s-pipe, TRD exhaust = NO rasp.

 

Resonator all the way... Checkit:

how much do those cost?

 

Resonators w/install depend on where ya get it.

Erik - The_Instigator got his for $105 installed

 

"Micheal Knight" to the rescue!

 

i know resonator is the answer.

i knew way back when. haha i was the 1st few who had the AW header in the begining.

im jus stating this for those who believe that the header wrap in between the runners will help eliminate rasp...

next mod will be new mid pipe with hi-flow cat and resonator

 

hi performance resonator shuts my rasp off lol

 

i wrapped my header and spipe but im still on the lookout for a exhaust. now this really makes me wonder if i will get rasp, but i could care less =)

 

yes the exhaust wil make the rasp louder
