Header Wrap on Test Pipes

synolimit

Lol how would a pipe change the noise? A 2.5" straight piece of pipe isn't going to sound any different then anyone's else's. HOWEVER, test pipes that have Helmholtz resonators like the arts or an inline resonators will change things. I wouldn't sell them, I'd fix them.

I have long tube headers like shovelman and the rasp was horrible! I added some Helmholtz in the X pipe right where it bolts to the header, so basically they're installed close to where the arts would be in their test pipe. 90% of the rasp went away! I still have 18x4" inline resonators and the mufflers which are like 18x5" resonators. I don't think inlines do as much as Helmholtz's. I plan to remove the inlines and mufflers and see what it sounds like. Then I'll add Helmholtz to the rear like the motordyne CBE if I don't like it. If I still don't like it I'll add the 18x4" inlines back in.
