High Flow Cat, Test Pipe

I bought a high flow cat and flanges for less than $60. They're not crazy expensive if you look. Personally I like breathing

It sounds like the cat is the last real restriction in your setup though, so with either a high flow cat or a test pipe you should feel a bit of difference.

I popular throttle body mod is to get a jeep 60 mm throttle body and mod it to fit the 420a on an eclipse. Not sure if you are going to want that big for an NA application without porting the manifold to match the opening of the TB.

I doubt it was an actual "high-flow cat" as those are usually over $100. Probably just a test pipe. I bought a test-pipe off eBay about a month ago and they claimed it was a "high-flow cat", but I knew it obviously wasn't.
