A few weeks ago there was an exotic Corvette noise thread. I may have what some have been looking for. I have tested 12 different sets of headers on my stock long block '03 Z06. I had the opportunity to test a set of 180 degree headers , custom built by ATI in Wixom , Michigan. Car sounded like very angry large displacement V6. Anyway, made a video clip for forum members enjoyment.
Car made great HP, among the best , but needed to run the car in open loop to prevent fuel trimming (which would be really confusing to the cars computer). There are some fitment issues on these cars with 180 degree headers , but it can and has been done obviously. ATI may consider building these if there is interest albeit more expensive obviously than other commonly available header combo’s. These headers were custom built for the ATI in-house hot-rod.
Sound clip is with 180 degree headers, no X-pipe, and a set of Borla Stingers, enjoy…
Sorry server seems slow, allow to fully load before viewing, sound clip is choppy.
GSXs Z06 sounded sooooo much better than that crap… IMO.
EDIT: I just did a blind sound test with 2 other people (sitting in another room) without telling them what cars these clips were from, and they both said the clips were of Civics… and when I told them one was of a Corvette, they said that the clip of MrSmith HAD to be the vette… LMAO
ok after watching both … i really don’t think you can accuratley compare them. i haven’t heard GSX’s but i do think it would have and for this year if everything goes through for him WILL sounds better…
so these said headers are a true dual set up all the way back ? no x-pipe? hmmm thats why it sounds like that i would bet plus the borla stingers muffle a lot of sound…i bet it would sound different with straight pipes… sounds ok to me
i think this sounds better to me but thats just me
That sounds great. Of course this car must have a different cam where as the other guy said that his exhaust is on a stock long block i.e. stock cam. The cam really makes the sound of the car in the above clip.
