I already have borla TD exhaust. I know i'll need a reverse y pipe to make it fit with the TN down pipe.

Apexi WS2 has a single 3" middle pipe. where the Borla is a true dual with 2.25" piping each!

do you guys think if I switch to Apexi WS2 i'll have better results with TN?


cheers.

 

I have that combo, the only thing i dislike is the sound, its very very quiet. its quieter than a stock 350z. I'am not sure if you will get any gains by switching the exhausts.

 

I have the Apexi WS2 and love it with my TN kit..

 

Mia, do you think i'll benefit from switching from borla to WS2 ?

 

I doubt it. The Borla should be flowing plenty for the power you are making. At lower boost and HP levels any decent flowing exhaust should do and switching is a matter of preference. If you are going to build the motor and shoot for 500 or 600s a much larger exhaust should be considered mandatory.

 

I'm going through this right now too. I have the Borla and just got a TN kit. I love the way it sounds NA with resonated test pipes. MY favorite sounding exhaust by far. But I was wondering how it would sound with the turbo and if I was really going to lose that much power because its not a 3".

I'm not sure if this would be reasonable but what do you guys think of having a shop custom make an exhaust to mate up to the Borla muffler. And if considered would it be better to run a single 3" pipe or something like two
2.5" pipes?

 

Borla TD will definately gain more power. I had it before and dyno'ed it too. It gave me pretty good gained through out the power band. At idle and normal driving...it's pretty quiet, but when you hit full throttle, it sounds pretty good and not loud.

 

Borla dual worked for me at over 550rwhp.

 

How did it sound? I am in the process of installing the greddy kit and I was thinking about cutting the resonators off the borla to help give it some volume, but not sure if this will sound good or bad.

 

i cut the resonators off mine, and off a customers. sounded awesome, im sure you will like it. I got a ton of compliments on the sound back then, which I cannot say for the dual 3" i have now. One of my friends told me that now my car sounds like a late 90s V6 mustang with exhaust... after he said that, i can totaly hear it in there - except my RPMS climb a little faster

it definatly sounded better with the borla and cutout resonators.

 

Awesome, I just might have to cut mine off soon. Was it a lot more quiet with the resonators on or was it just a subtle difference.?

 

After removing the resonators (and welding in staight pipe replacements of course) the car sounded exactly the same to me as it did with the resonators, just more volume. It had a classy sound with minimal rasp.

OH, it wasnt much louder. I still wished it was a TAD louder, but it would probably be perfect for most guys. It was by no means LOUD, and would NEVER get attention from the law or anything, it definatly wasnt loud. If anythign I would just say that it became audible, since it hardly was before.

 

Awesome I will definately be doing this. Is the borla pipe exactly 2.25 inches?

 

yea im pretty sure. But now that I think of it - we might have just welded in some 2.5" stainless we had sitting around? I cant remember now.

 

Do you think it would benefit to run 2.5 stainless all the way back? Or are you reffering to replacing the resonators themselves?

 

WS sounds sweet with TN. It's not that loud, but not not conservative like the Fuji. It's not a 3" though, it's about a 2.8?

Plus you'll have to cut the Borla if you want to keep it.

 

you couldnt, because the muffler inlets are still 2.25", so there wouldnt be any benefit. We are just talking about replacing the resonators.

 

Ah, gotcha. So basically run it as is with a custom Y pipe and if you want it louder replace the resonators.

 

Great info. thanks guys!


I think I'll go with a custom exhaust w/ dual mufflers. now I have 2 choices;

1. dual exhaust - 2.5", 2.75" or 3" piping?

2. Single exhaust with 3" piping.

which one do you guys think will work better with TN?

P.S, I'll be using APEXI mufflers which have 2.5" inlet, is it ok to bolt 3" exhaust piping to those 2.5" mufflers?




cheers
