Hey y’all, I have a 08 G35x Sedan and I want this thing to be loud. I currently have Borla XS mufflers (not catback) and some titanium tips on them. They however don’t really get the job done well enough. I really wanna beef this thing up for a low budget. I was thinking about maybe getting cut outs or just a whole new kit. I haven’t done anything with the engine yet either, possibly new intakes??? Idk yet, any advice?

 

You have the HR motor, biggest performance gains are a true dual cold air intake, high flow cats/test pipes, and an uprev tune.

I would leave the Borla, get a set of test pipes (if you don't mind it sounding like ****) or some high flow cats (if you want it to sound decent), and get a good intake on it like a Stillen or Z1 intake, once you have those installed get it tuned. If you don't have a local Uprev tuner you can e-tune the thing, contact user Seymore4 he is a reputable e-tuner here on the forums.
