XO2 exhaust (HKS Knockoff) with magnaflow x pipe will do the job just right.

 

F.I. HFC's with HR Y-Pipe. I think this is best for $500 or less. Going too cheap w/ an aftermarket CB seems like trouble.

I sold my stillen for around that- and with stock cats it would sound pretty amazing. I'd definitely grab one of I had the same goals as you do.

 

If you're on a budget, just get air filter, z-tube, plenum spacer and HFC.

 

x02 off of ebay some are 290$ magnflow x pipe 85 shipped on install should b around another 90-140 so its perfect for your price range could be a lil less than 500 or a lil more

 

Duel catbacks? Are you setting your car up for battle?

...oh. Dual catbacks.

The best sounding catback for under $500 on the G? OEM. Anything else is probably going to use shoddy resonators that drone like hell.

If you really want to spend $500 on performance mods for the G, you'd be better off getting a MD plenum spacer, test pipes, and maybe a y-pipe.

 

this post is almost an oxymoron/paradox. the best you can do is hks replica ~$400 and Magnaflow x-pipe ~$80 this does not include installation and welding fees. if you're also paying someone to install this you'll be at or around $800

 

lol, so bump what your willing to pay up a few hundred, buy an invidia and call it a day

 

craigslist! ive seen a few nice exhaust setups for cheap, who knows you my get lucky.... and i 2nd selling that GTR bodykit.... Mad rice son

 

I've since looked at the garage- is that what they call the GTR body kit?

I don't want to offend... But you've GOT to be able to find parts that fit better than that- before you muck with the exhaust.

I'm a third on dispensing with whatever that kit is.
