lol wow you responded fast, i was refering to passnu's pic, just to clarify
,
Correct the piping is larger until it hits the axle-back. Does it increase horsepower? who knows lol. I feel a difference top end. But when i get my Tanabe Exhaust I'm going to dyno it and see if it really does something.

I'm thinking the best thing to do on a budget would be to keep the OEM system and just cut out the resonator and secondaries for consistent exhaust pipe diameter, most weight reduction and guaranteed increase in sound. Maybe too much sound..but I'm not sure.

I think you are right on that its going to sound better IMO, be less weight, larger diameter pipes, possible increase in MPG, and HP

is it really still 2.25 on the aftermarket? i cant say that I recall what the Tanabe is? So its going to get restricted as its hits the aftermarket and makes its way to the mufflers...anyone know for sure if this is the case?? I am still on board to try this out either way. we can always custom that rear section so that its constant 2.5 from mid pipes to the tips....
-The Tanabe is 2 3/8" where it connects with the large resonator
-The Tanabe pipes going into each of the mufflers is 2"
-Coming off the primary cats to the large single resonator is 2" diameter as well.

So then what is the benefit of the pipes changing? On my past cars I cant say I measured but they started at 2.5 then went to 3"...I had this done with a Greddy exhaust in the past where I had a custom 3" mid pipe and "test pipes" so I was true 3" from the Turbo all the way back...Only thing is I never did check the aftermarket exhaust if it was a true 3" to the tip....makes me wonder now. I know 2 totally different cars and setups here but just using as an example.
So is there a benefit to the 2.5 mid pipe in size I mean?
You are the guru on this stuff here so I am all ears

hey Mike if you wanted to keep the piping equal 2.5 all the way from the header back then order the entire Megan set. The axle back part is also 2.5. Louder then the tanabe though.. depends how much sound you want.

Thanks...I don't care for the blueish tips (
what ever that is called)...I am not a fan of that look. I like the Tanabe and will still try the mids out just wonder if there is a pro or con to the pipe diameter getting smaller towards the end. I guess I could ask 2 experts and get 2 different answers. I guess want would be nice is to see a DYNO with the mids on my Tanabe compared to the full Megan set up to see if and where there are any variances. I cant imagine its a huge deal and I am not expecting to much in gains from them. Should free up the car as I am OEM mid pipes now and give it some sound that its lacking. I may not care for the extra sound? Like sincityIS mentioned I am not looking to have the loudest exhaust out there and don't need that kind of attn where I live. I get the looks as it is because of the tinted windows

haha I gotcha. I'm the same. I don't want to have to much noise. I came from a modded Subaru WRX with full Catless 3 inch turbo back exhaust.. Man was that thing loud lol. I am going to safely assume it SHOULD add HP just because it eliminates the secondary cats. Correct me if I'm wrong but even James (CaymanDive) stated that he gained some low end torque and some hp from deleting the cats.

I would like to put the S/C on the car and play around with it. But LMS is no longer and Toms kit is outrageously expensive for the small gains IMO. So I am back to the basic performance mods to get a little something for now.

I have the OEM so I went to measure and its also 2 3/8 where it connects to the large resonator. Its the same size till they join and go to each muffler. I can not measure that area but it looks like its 2" if not less and bent in a few areas. I really wonder if any of the aftermarket exhaust are truly larger and consistent in diameter now!
