I came across some inserts that go either in the header collector or behind the CAT (for street drive cars) in Summit's new catalog.

I went to Car Chemistry's site and they have some dyno charts showing an improved in low and mid-range torque and HP.

DynaTech has a site, too, but no dyno data.

These inserts were designed NOT as power producers, but to lower the dB level for cars that have to compete at tracks which have sound limit restrictions.

I was wondering if anyone has tried either of these inserts and what their results were.

Thanks,

Good luck on this one. I posted the same question a couple months ago. I all I got was people that have never used them and just telling me pretty much the same thing as their description in their website. Good luck though.

Thanks, Tom.

I sent the owner of Car Chemistry an email asking for more information.

Car Chemistry is about 5 miles from me, so I'll do a follow up with them to see what's what.

I'll post anything I come up with.
