Review: Strup Headers & UTR High-flow Cats

Review: Strup Headers & UTR High-flow Cats
I had a set of UTR high-flows & Strup headers installed a week ago and here are my findings.
Performance:
The a$$ dyno says that there is a gain. I feel that I have gained power throughout the whole powerband (I feel a slight gain in low-end power, more in the mid-range, and the top-end just explodes ). I can go from 60-120 noticably faster.
Sound:
The addition of the headers & cats has made my exhaust sound deeper, however it has added some more rasp (I actually dont mind it at all). At cold idle startup and at WOT the exhaust note is LOUDER (It wails like a banshee ). It sounds very exotic and turns heads (I'm using an Invidia G200 BTW).
Tech:
Prior to installing the headers/cats I measured the ID of both parts. The UTR high-flows are 2.25" ID in/out. The Strup headers start with a 1.75" ID at the primaries and end at the 2 3/16" ID collector.
Conclusion:
I feel that these parts are worth the time and $$$ (installation costs). You can see the pics at the bottom and I will post vids tommorrow when I get the chance. Now I got to save up for an APS plenium, cams, UTEC, & tuning. Thanks to MRC Motorsports for installing this for me and for the food .

interesting choice of cats - given how many problems there have been with kinetix and crawford with cracking, i'm curious how UTR stands up given their, erm, less than stellar other products.

Thats the reason why I went with the UTR's. They have a metal core & they bolt on to the cat brace so hopefully they will last (for the $$$ I paid for them they better last )

i've read that part of the problem was the aftermarket cats bolting onto the stock brace, thus putting disproportionate strength on certain areas........hence why crawford and kinetix no longer have them bolt up to the stock brace

cool, I have the Strupp headers and UTR resonated test pipes. They arent installed but your review gets me excited.
Also, if the Test pipes crack, i will be pissed for paying 340 for them, when i could have just bought some cheap ones for 100 dolla.

hope this helps shed some light on the situation.

However one difference is that the UTR cats do have is a metal core as opposed to a ceramic core. The failures I have read about were all core related, nothing to do with the mounting tabs causing failure as you stated.If this was the case you would see alot of stock cats failing for the same reason. The mounting tabs actually add integrity to the entire exhaust assembly and prevent the stressing of the flanges at the headers and exhaust, thus preventing leaks or cracks at the flanges. If the mounting tabs caused exhaust failures then theywould not be there from the factory.
hope this helps shed some light on the situation.
