Hi guys,

I plan to replace the 60mm single js racing exhaust with the Js racing 70RR 70mm titanium single exhaust to work with my vortech setup @ 12 psi.

Does anyone has tried this in order to share his experience with me ? AFAIK when you go FI a bigger diameter exhaust is a must have.

Thank you

 

ya...thats my setup only with a Comptech blower now at 13psi......better put your ear plugs in.....my ears will ring when i get out of mine even under normal driving + i dynomated the rear trunk(helped alittle)

if you like it loud though....the sound is nuts at redline.....never heard any S2k better than a high lb pulley with a J's Header/Ti-70 single pushing close to 400whp

 

I got that setup on stock boost with a vortech..

I guaranteed that if you daily drive your gonna sell the exhaust like i did!!! lol

 

sorry kind off topic, but has anyone used a J's 70rr with a turbo setup? How was using a J's 70mm setup with a turbo setup? Or is it the same noise with a supercharger setup?
