I want to know who makes the loudest and best sounding exhaust system for a 90 300ZX NA? I have heard that B&B exhausts are very loud. I was thinking about getting the HKS Carbon rapped T-1 exhaust but I havn't heard anything about it's performance and sound gain. If anyone knows anything about either of these exhaust systems, please reply. Thanx.

 

B&B will be loud on an NA. On a TT, it is loud but not all that bad. Once the turbos spool, some of the sound is killed off. But if the TT has downpipes and test pipes, it gets quite loud. :-) It's the best exhaust note I've heard on a Z bar none. On the NA, it's even louder.

 

I believe the HKS Hiper is pretty loud too!

 

Yeah, but it's ugly...lol It looks like a ricey potato launcher exhaust.
