Supersprint or Evosport Headers?

I am looking to buy a set of headers and was wondering which one is best. I've heard a lot of great reviews on Evosport. The only reason why I ask is because it seems like the cars with Evosport headers have totally different sound from stock headers. More raspier and loses the V10 howling sound. More of a muscle car sound which I don't like.

I love the way how my sec 1 & 2 Meisterschaft GT sounds and I would love to keep that same sound but louder. Which headers would be best?

My vote is Supersprint! Same length as stock headers.

While evosport headers produce the same top end HP peak. Supersprint gives you more hp throughout the RPM range.

Someone correct me if i'm wrong, but Supersprint you get what you pay for vs evosport.

As for sound louder for sure, but yeah seems all of them get deeper.

I think the new RDsport - Racing Dynamics header is very nice. A friend of mine Emailed me this picture, it looks TIG welded and pretty much equal length. I'm looking for something that can at least let me know some dyno numbers on it. I'm also in the market for a header.... the supersprint and evosport headers look like edelbrock made them....bad craftsmanship for that kind of money.

Those RDsport headers look pretty sick. Ive had the SS in hand and theyre good quality. May not be show polished or anything, but the design is good and workmanship is quality.

Conduct a search on RPI GT Headers! It utilizes the stock headers and at the same time give you significant gains. It is an excellent choice for people who need to pass smog test without going through the hassle of 15hrs of labour to remove the headers. If you can wait long enough (3-4 weeks), I will provide you with my personal feedback as I'm getting a set from RPI.

Modifications:
  • Engine: RPi / PC Stage 2 ECU Software, RPi ST Underdrive Pulley Kit, RPi Ram Air Intake Kit (Black) & Block Off Plates, RPi SV1 Oil Cooler (Black), M-Sprint Booster
  • Exhaust: RPi GT Headers, RPi Hybrid X Pipe Section 2, RPi GT Section 3
  • Exterior: Vorsteiner CF Vented Hood, RH Type CF Splitter, Upper CF Mirrors, CF Side Skirts, CF AC Schnitzer Style Trunk Spoilers, CF Side & Kidney Grills, Black Powder Coated Lower RaceMesh Grille, CF Pillars, all Roundels in CF, Red Angel Eyes, OEM Smoked Tail Lights, Smoked Side Markers, Brake Calipers Painted in Red with CF ///M Decal

RD Sport stuff is making a real impression.

As for Supersprint vs Evosport - it's got to be Supersprint.

One thing about Supersprint - their exhausts make the extra power they say....every time.

The RDSport headers do look very nice. Are they truly equal length?

I have Supersprint headers basically because when getting headers this was all there was as a choice in the market. Back then (Nov. '06) there were comments that you had to hurry because production was going to be limited. I fell for it.
I will say that I have been very happy with the SS header performance.
I believe that the different headers available all make the same relative power.
In actuality the removal of the primary cats (built into the stock headers) is what truly makes the hp gains. The RPI product IMO proves this.
The exhaust note achieved may have more to do with the exhaust system utilized.

Exactly. Wishful thinking, but I'd love to see some dyno numbers on stock headers without the primary cats.
