I'm trying to figure out which size test pipe I should get. I have a 3" downpipe and a 70mm exhaust. Should I get a ultimate racing 3" test pipe or the tr1 70mm test pipe? I have the t1r 70mm sparrow exhaust.

 

70mm

 

Anyone else?

 

if you have the tr1 70mm exhaust...why not get it with the tr1 70mm test pipe.

 

Didn't know if it'd be better to match the downpipe.

 

it would be better the get the same size. otherwise your just bottle necking your air flow.

 

It seems like I can only get the t1r in 63mm anyone know where I can get it in the 70mm?

 

Give A&J Racing a call.

 

70mm tp comes with it when you purchase 70mm sparrow, unless you bought it used.

 

I know it's suppose too... The guy I bought it from said it didn't come with it. I kind of figured he was full of it. I called a&j and they could only get the 62mm one. I ended up getting the invidia 70mm test pipe.
