I found a really good deal on an F1A, am I crazy to put this on? I was looking at the Roush TVS but for the deal I'm getting it'll be hard to pass up. If tuned down to be safe for daily driving does anyone forsee any problems? It's going in an automatic and I will be (at a minimum) upgrading the driveshaft and exhaust. Any reason NOT to get it, let me know. Thanks.
