Hello, i know there was an old post where someone asked this before but i was wondering if anyone else had tried this or could give me some advice on a set up since i'm by no means an expert in exhausts.

i'm not set on the idea yet, but i have an 08 sport coupe and i'm thinking of upgrading the Y pipe and possibly ditching the dual exit exhaust to run a single (3inch ?) pipe out to a single muffler.

I will be staying NA

 

what are you going to do with the other bumper cut out?

 

my first thought as well.

^^ that concept z link will help... I've also seen a rear diffuser for our cars with a single cut out somewhere- but would have to dig for it

 

google =

 

Just curious, isn't 3inch exhaust more for FI, whole 2.5-2.75 is more N/A.

 

wow, thanks for this link! I'll be contacting them about this. i dont think the extra cutout would bother me much but if it does, i could always just fill it in.

that's what i thought too but i'm not sure what size piping would be best. doesn't the stock exhaust just split into 2 2" pipes after the y pipe anyway? a single 3" pipe would only be slightly larger

but then I would then need a y pipe with 3" outlet since i believe stock is 2 3/8", right?

 

I haven't done it but there's a Tomei exhausts..

 

aside from weight savings.. unless you want it for aesthetics.. dont see why you would go this route when there are true duals available..

 

So after chatting with John @ Z1 motorsports, i ended up dishing out a bit extra and going with the Tomei expreme titanium muffler and y-pipe. I did not know they had an application that fit the g37 so thanks for the heads up monytx!

The claim is the entire catback weighs in at less than 18lbs with some gains and i also personally like the look of a large single exit over dual

unfortunately i won't be dyno-ing before and after so those power claims will be a mystery until i do, but i'll keep everyone updated when it comes in and i install it

 

google again =

 

Doesn't look as good as dual, but sounds bitchin.

 

yes, i saw this video after googling for tomei exhausts but i doubt i would have found it without being so specific. I tried looking up videos of anyone running single exits before and that clip never came up soo

 

Idk, looks and sounds a bit ricer to me

But to each his own I guess. It's certainly doable.
