Anyone running HFC with stock catback?
Just wondering how much it change the exhaust tone and the performance gain. Catbacks cost too much $$$ I just can't see myself getting one. HFC on the other hand cost about half of the money and it replaces the most restrictive part of the car.

I heard it really a waste of money to replace the exhaust on a G because there is really no system that will give more power than stock< so if your getting exhaust it's basically for sound

I recently replaced the cats with berks hfc (still have stock exhaust for now) and I must say hands down best bang for the buck, makes the muted stock sedan exhaust really come alive like the Z's and G coupes maybe a tad deeper but same tone...Sound great and I really pleased with it...performance wise it does feel a bit more peppier and free flowing through all rpm ranges but the sound really did it for me. Now I can wait a lil longer till my exhaust (Invidia for AWD's) is made. I actually have sound clips before and after and if someone could help how to upload'em i post'em (files are pretty big - hd video)

you know what i never really heard the rasp..at all like some mention nor and get any CEL (berks are good like that) however i do have that hiss that all seem to have after reving, its not really noticable...and I did have some annoying exhaust vibrating/grindy type of sound for the 1st week I thought it was because i didnt have the gaskets on there. Berks apparently forgot to send'em to me and I couldnt wait so I got them hooked up anyways. They are on now but still have some of that vibrating(like 2 thin pieces of metal vibrating against each other) sound only around shift points but it seems to be quieting down a bit...idk but i think it from the stock exhaust cuz i used to hear it but in a more muted fashion when it was stock new as well...ill see when I get my exhaust.
Ill try to work on getting those vids up
