I think I already know the answer, but I want to get some opinions based on peoples experience.

I have a Megan Racing 60mm resonated test pipe lying around in my garage. I never installed it, and it came with the car when I bought it.

I have a brand new T1R 70R EM dual coming from Evassive probably next week. Is it worth buying a 70mm test pipe, or just using the 60mm test pipe. I like the idea of having a resonator in the test pipe to keep it a little quieter. My question is, will there actually be a power difference between the 60 and 70? I imagine maybe like 1hp difference between the two.

Keep the one you already have. If you were forced induction my answer would be different.

Considering an entire exhaust system adds about 5 hp, the minimal size difference on a TP wont really do enough to bother getting a new one.

+1, if your butt dyno knew the difference, it would be liing

Yea you guys are saying what I already was thinking. I was bored at work...imagine that, so I figured I would make a new post, and did not have much else to discuss. I just hope the welds on my megan TP don't break like some others I have seen.

No they do not. Atleast not the T1R 70R EM Dual.

If the header has a 70 it would make more of a diff.
