Fist off I was told the biggest exhasut piping you can fit without issies is 3" is that correct. I will be doing a LS1 swap in my FD soon and I need a 3" catback. I would like something fairly quite but I dont want to sacrfice flow. I have seen the Greddy Ti exhaust for $560. Seems like a good deal. I am not a fan of HKS exhasuts cause the 3" systems funnel down to 2" inside the can. Let me know what you guys recc. Thanks

 

I'm digging my setup.. A'pexi GT catback is > 3 inches in some areas, and bolts right up... no fitment issues. With the silencer in, it's literally like a normal, unmodded '7... without the silencer it's only *loud* under WOT. Of course, it may vary from car to car.. 'specially if you're going LS1.

 

Ya I will need tje scilencer to get a sticker. Hopefully they dont notice the LS1 lol.

 

pmed you....

 

What do you guys think of the Greddy 3" Ti exhasut $540 is a steal and it will be quite when I need it with a scilencer.

 

I read somewhere yesterday the GT with the silencer in was more restrictive than the stock exhaust on a 7. Just thought Id mention that.

 

I wont be driving around with it just to get a sticker. I bet it does flow less it goes down to a little ***** pipe.

 

yeah i have the apexi N1 ExTi, the pipe outlet is like 1.5-2 inches with the silencer...and i'm leaning in the 1 inch range...i think i might throw the stock back on for now to lay low =p

 

I am thinking the Greddy Ti is for me.

 

No reason to go Ti unless you just want to spend the money. Exhause weight is low and on the rear wheels.
