InfinitiForever

I currently own an Infiniti I35. I want to make it sound louder, even if there is a little rasp. I am going to buy an Infiniti G37s in a around a year, so I dont want to spend much money on this car. I am well aware that this is illegal but I no longer and live in the city and am willing to deal with the consequences. What exactly do I need to do and what parts do I need to strait pipe this car?

^ Cosigned. He's basically named all your options. Custom exhaust shop would be the cheapest route. Have them gut the cat, chop the resonator and weld a straight pipe in, and get one of their cheap straight through mufflers or just keep the stock one (would sound better if any). All that for around $100-$130 (around my area that is). It would sound loud and ricey but that's my opinion.

Personally, id try to score a used catback. $230 give or take and about $60 to have it installed. Approx $300 setback.

Or an eGay knockoff will cost even cheaper new...$200 or so shipped. Plus install...
