You also get the quality for what you pay for.
The Sinister kit I have now costs something like $365 ($250 when I bought mine) throw in a up-pipe if you don't want to use the thick block plate in the kit for around $225.
I liked the idea of retaining the stock look and the grid heater.
I'm not having any issues at this time, that doesn't mean I won't.
If I have problems I'll just have to fix it, if I don't I've saved a few $$$.
If I was much younger, raced around and wanted as much power as I could get, I would have gone with something like SDP (a provin quality name) and a LB7 up-pipe.
If your dead set on Rudy's kit and since you have not gotten a positive response on this thread and the others you or someone else has asked the same question.
Please give us some feedback on what you think if you end up going with Rudy's.
