Currently my FD has a custom 4.5" muffler on it. Well i dont know who made it or what the specs are. All i know is it is loud as all Hell. Hence cops allways seem to look for me o a 1/2 mile before i get there. If i get on it anyhting above 4k RPM is very very noticable. I was just wondering what the best muffler is i coudl put on with out losing any power. If i stay any where near this loud i am going to get lots of tickets. Hell i'm sure i could get fined for the DB level in most rural area's let alone all the attention it get's. To top it off it looks like a damn coffe can stickin out my *** end. I just figure i got the ***** to back up the sound. So it's not to ricey.

Try borla mufflers.

Mazdabation

No you want to use the Borlas as a resonator in the mid-pipe.

For actual quieter sounding mufflers, go with something like the Racing Beat dual tip.

They have a stock look to them and keep the car at a nice DB.

Then put something like the Borla in the mid-pipe, which will quiet it down even more.

Some have said its as quite as stock with this set up.

Greddy sp work well also. The rb is too quiet for my taste.

Mazdabation

I have also heard that the GReddy SP is a nice sounding exhaust.

Yes, like Silver just said so you know, the Racing Beat is very quiet.

I love having an exhaust with a silencer. I've tried everything from

Apexi, HKS, and Greddy, but have had the best luck with an off

brand I found with good build quality and a removable tunable silencer.

Is the WHOLE EXHAUSE 4.5"? Or just the inlet and outlet of the muffler? If it's just the muffler, it shouldn't be THAT loud. But if you have a DP and MP combo, then I understand.



If you have a DP and MP, get the RB dual.

Yeah I have Blitz its sounds great not to Loud and it came with a free silencer just if You wanna run quiter. A friend has the GReddy SP on his FD sounds great too. I would go with one of them before Borla.

teknics

if you run with a silencer all the tim you should save your money and just buy a smaller diameter and quieter designed exhaust system, at least that's how I think about it because I too like the sound with a silencer but i cant see spending my money on a system design to be big and loud and just silencing it, ya know?
