Exhaust
 

Should i get a spec d exhaust on my g35 or muffler/resonator delete

You should read the forum headers before starting new threads lol. The forum you posted this in specifically states in big, red letters "No Car Questions" so I moved this to the most appropriate place. But welcome to the family, we're glad to have you.

I'm not a fan of muffler deletes but the Spec D is a cheap knockoff of the HKS and there are a lot of these same exhausts sold under different brand names. They tend to be inferior systems with crap sound, poor fitment and shoddy materials so I'd go another route. Look for a used name brand system if you're on a tight budget like the Invidia Gemini, Nismo et.

Finally this is one of the most asked questions on the forum on which there are countless threads discussing exhaust choices so there's no need for another. I'm closing this one to new posts (please don't start another on the same subject), use the search function here and Google to find the answers you seek.
