Where can i get a flowtech cutout. Also what size will i need my car came with flowmaster exhaust so do i need a 3 inch?

 

I bought the Summit ones, you can also get Flowtech from Summit as well.

It all depends upon wher eyoure going to put the cut-out. If youre going to put it before the cat-you'll want the dia from there, if where the cat is you can get a 3 inch.

 

I'm wanting to put it right after the y-pipe so i guess i'll have to go and measure the y-pipe correct?

 

I think I bought mine from summit as well. Now I buy everything from www.thunderracing.com They have great customer service, and they are only one state away from me so shipping is always fast
