Also have full spare which could allow some resonance under the trunk area.
Think a layer of dynamat under the spare would cure that?

I would like to see dyno's showing a loss with a larger system. Typically, going larger will produce diminishing returns, but I can't imagine an actual loss, especially over stock. Our stock setup is right on the verge of 2" maximum flow capacity, so minow bolt-ons and tune would be on the verge of maxing out 2.25". I have nothing against either, I'm simply curious as to how 2.5" could dyno less than 2.25".

They were probably comparing it on a completely stock motor. I would venture to say that without airbox mods, the 2.5 killed too much backpressure and increased the pumping losses. You have seen that modding airflow makes the smaller exhaust a limiting factor, so going too large on the exhaust could make the smaller airflow a limiting factor. I have no doubt that the 2.5 produced more hp/tq vs. OEM, but it might not have outperformed the 2.25 vs. OEM

It's gotta be solely exhaust without any other bolt-ons.

I chose to do so I'll dyno an see f I can crank out any more with a 2.25 exhaust.
I'm just veering away from custom and went with someone I knew fit. My 05 TruBendz was horible fitment problems till I fixed it. And it was a nightmare fixing them to the point after it was fixed I didn't want it anymore.
That would be great. That's a good point on the header as well.

That's sad to hear about TruBendz kit for the 05. Most guys I've heard using them haven't had such a bad experience. Hell, I'm hoping they or someone comes out with a stainless piping kit so I can change out the crappy stuff I have on now!

That's what got me as well.

forgot to post back have the magnaflow with steeda intake now and it does really well(older mitsu eclise gst couldnt pull away from me those made 210 hp stock i thought it was a regular one and at the light i heard psht ) . I'm gonna be fabbing up a test pipe for my crappy secondary cat can decide on doing a step2.25" like the rest of the exhaust down to 2" at the connector or 2" all the way since the front muffler was made to fit the exhaust? i've got 6 years before i have to smog again but id like it to be reversible if i get pulled over and get sent to a ref
