Does anyone make a 3.5 inch downpipe and midpipe or high flow cat? Opinions on possible pros and cons...?

 

The bigest diameter DP is from Corksport.

The bigest stainless steel exhaust is from Border Racing which is 3.5" diameter. They also make either a hi-flow cat (or a resonated MP) but not sure of the diameter.

The Apexi GT is 3" on one end and then expands to 3.5" just before the can.

Contact Jason from JT-Imports about the Border Burnout type 2 exhasut system.

 

I have a 4" TRUST exhaust. I'm looking for a 4"DP for a JSPEC car...any suggestions.

 

Thanks! Is there anyone running these sizes on this board?

 

Checked Corksport and BORDER japan .. I can't find anything 3.5"
