About 1 year ago I did a lot of research into replacing my OEM manifolds with headers, but ultimately decided to install Capristo brackets and stick with OEM on the manifolds. The main reason was I do like the OEM sound and was (and still am) concerned that the headers would change the pitch and sound too much for my liking. I didn’t want to go and spend a Thousands on headers to be disappointed with the sound. But as I continue to be concerned about a cracked manifold, I started looking into buying headers again. I noticed that over the last year some things have changed. Some prices have gone up quite a bit, and there are some new options. So here is a summary: Capristo- I was actually leaning towards going with Capristo headers last year despite the price being significantly higher than AP. But I was very disappointed to see that over the last year they have raised their prices about $1000 to a list price of $6900 (this does include their blankets). I am sure the distributors can get you a slightly lower price, but I don’t know how much lower. I was going to go with Capristo initially as my research had found that their use of a higher grade steel resonated at a higher pitch, and ‘might’ have had a better sound than the AP or Fabspeed headers that have often been described here as being a lower tone, and in some people’s opinion much louder than stock. But the sound quality improvement of Capristo headers vs. AP seems a bit uncertain, as I can’t even find a good YouTube video to compare how Capristo headers sound. You think they would put out a video, but there is nothing like that I can find on their headers paired with a stock 430 exhaust. And frankly at a price north of $6000, even if they did sound slightly better, I think they have priced themselves out of the market, as that is ridiculous for stainless steel tubes! AP- These were the other headers I was seriously considering. I saw a thread from Vivid Racing that they are selling these for about $2250 in 2018, although they do not come with blankets, so that will be an extra cost of around $1500 or you have to wrap them. My only concern with the AP product is there were several threads on fchat where certain members complained that they were “obnoxiously loud” and that the tone was a lower pitch than the stock 430. I don’t mind the loud part as that is probably due to no precat (and the stock 430 is a bit too quiet IMO) but I would rather avoid the lower pitch part as I don’t want a Ferrari sounding anything like an American V8. Fabspeed- These headers are supposedly the exact same as the AP product. I saw Fabspeed had a recent thread offering a sale price of $2290 which I believe is quite a bit lower than normal for them (I am guessing to compete with AP). But unfortunately it also said in the thread this sale price had ended, so I guess this takes me back to AP unless Fabspeed would revisit the sale price. Top speed- This is another header I have seen discussed that is offered for an outstanding price, I believe somewhere around $900! Most owners seem to be pretty happy with them from the little I have read, although the cons I have read discuss the precision of the product such as the tubes possibly not being equal length. If anyone can offer any opinions of Top speed good or bad, I’d like to hear them. Certainly their pricing is very attractive, but is the quality as good as AP? Soul Performance- Never heard of these before, but saw them listed on eBay for about $1700. I couldn’t find any info on fchat, so have no idea of the quality, or if they are the same as another product just with different branding. Does anyone know anything about these? I’d love to hear any opinions from owners about the choice you made, and if you are happy, or would go in a diffferent direction if you had to do it again? Specific questions I have: -I would like to hear any opinions on the sound of AP/Fabspeed headers (with rest of exhaust stock). How does the volume and tone compare to stock manifolds? Is the lower pitch tone really noticeable? -Are AP and Fabspeed headers really the exact same product? -If you went with AP/Fabspeed did you buy the rather expensive blankets, or did you go with a wrap or ceramic coating? And finally if you chose wrap/ceramic coating, has it been effective in keeping the heat under control? These manifolds seem to be the Achilles heal of the 430, so the more info we can gather on the header options, the better.
