hey guys i did some research and didnt find anything but i was thinking about trying a full 3in from cats back single exhaust to a greddy tic tip. if not 3in im going to go with 2.5 but how do you think it would sound? ever seen or known of anyone doing a single? couldnt really find any sound clips or anything.

 

The rear bumpers are designed around two tips, if you go with one you'd have to modify the bumper otherwise it'd look retarded. That's why you don't see them being done (not that I've seen at least)

Also, if you want to achieve similar flow characteristics to that of a dual 2.5" exhaust, then you'd have to go with a 3.5". If your y-pipe is OEM or restrictive, then the single exit would be pointless.

 

I've seen it a few times, but in the Z community. haven't seen anyone do it to a G37

 

I think I will be in the minority to suggest that I like this idea... However, I think the rest of your car would have to be pretty aggressive to pull off something like this. There is another G on this forum floating around running a single exhaust. Like Sam suggested, if you could mold your bumper to fill in one of the factory exhaust cut-outs, I think it would look much cleaner, but, nonetheless, I'm interested to see this...

 

I actually talked to Tony at Fast Intentions about this. He said that if he could get a car in the shop, he would fabricate one up.

 

I like the idea, but have yet to see it on a G. I have seen it a few times on Z's but they put work into making them look right. You should do it and let us see how it comes out.

 

To give you an idea of what the final product might look like...

 

Ive always contemplated putting 3 inch pipe from the ypipe back out of a Aspec blast pipe muffler... I think it might be very very loud tho lol

 

Well nvm. Question answered.

 

That picture is where i got the idea. Im getting the rims (xxr 522) and was thinking about the exhaust. I agree on how it would look dumb becuase its meant for dual but because i dont get paid that much at my job it would have to do for time being.

 

Please don't take this the wrong way, but I wouldn't half azz my way with this mod because of limited income. If your current job doesn't pay enough to properly modify your exhaust and bumper then maybe modifying it at the time being is not the smartest thing to do. The posted G as you can see looks like the second muffler fell off or something

 

If it will do for the time being then you would run into various scenarios:
1) look retarded with 2 bumper cut outs but only 1 filled
2) buying 2 exhausts, 1 for now, 1 for later
3) buy 1 exhaust, fill bumper on the other side, and look like a civic?

 

I ran a single exhaust on my 03 350Z and I loved it. I had an Agency Power 3in single, Stillen 2.5in Y-pipe and Berk HFC's. It was insanely loud but it sounded sooooo good. Major drone at highway speeds. Mine didn't look funny from the back because I had a different bumper that worked well for a single. I think it will sound good and be different on a G37 but imo I would still get a dual just because the G37 is a classier car than a 350Z and it looks better with a symmetrical exhaust.

 

Are there benefits to single exhaust vs dual other than weight and looks?

 

Being different I guess

I honestly think it has potential if done perfectly right, but has bigger potential to look retarded otherwise
