But for the life of me, I couldn't get all the header bolts installed after trying for hours. I even had some ARP bolts so I wouldn't have to mess with the crappy studs. If I had the money, I would have done it the right way ( SVT ). There are inexpensive aftermarket converters around if you can't afford the full swap. Plus, I think the downpipe may be clogged or something. I've got a constant vibration lately and the exhaust has definately changed tone in the last few months. The weather has been absolutely crappy for weeks now and I don't have a garage. I will take it apart some time and see what's going on.
I also just really need the down pipe. I could care less for the header. Most of the ones I've seen look cheap and of low quality.
I would've never believed someone doesn't make a cat delete pipe for these cars but it looks like that is the case.
