Hello,

Just purchased a stock 05 G35 coupe 6mt. I love the stock exhaust sound, but would like it a little louder. Looking to improve the tone of the stock exhaust but don’t necessaily want to buy a new one. I’m in a unique position where I can do anything I want and won’t have to worry about emissions. Would hfc or test pipes increase the sound of the stock exhaust (which I like) without making it to raspy? Eventually Id like to do the full NA upgrades (intake,headers,plenum), what would improve the tone but not set me up to waste money.

Thanks
Mike

 

Hey mike, if you upgrade to a test pipe / HFC you will have drone. If you do just Cat back it should not rasp, unless it's a **** eBay exhaust.

 

"Welcome to the G35 Driver forums Mike!" The only mod you can make to your OE exhaust w/b to replace the muffler with a more free flowing unit like Magnaflow! Test pipes and high flow cats will drive you nuts with all the rasp! Factory cats are so restrictive and designed to work with the rest of the system, remove that restriction and it becomes over whelmed!
Again Mike, welcome and enjoy the ride...Gary

 

Art Pipes will replace the cats without any rasp.

 

Wrong! Art pipes are no different than HFCs or test pipes, you're releasing a massive amount of volume which the factory exhaust wasn't designed to deal with!

Mike, I have the Berk HFC and Invidia Gemini full catback exhaust combo, I am happy with it. Quiet on idle, no drone and not too loud but roars when you punch it past 4k. Here's a video of mine while getting tuned.

 

Maybe I misread the thread but it appears his end goal is doing a ton of mods. Art Pipes, stock y-pipe and Tanabe exhaust on mine initially, zero rasp. If emissions aren't a concern, might as well go all out.
