im lookin at buying this for the r but a couple of ?'s
whats the diameter of the pipe
and hows the sound in your opinion
thanks in advance

 

2.25" piping. Never seen or heard one in person ... sorry.

 

I had a thermal exhaust on my 95' ls. On that car the exhaust was quiet, but real deep. It had a great sound in my opinion. I have never heard it on an ITR though.

 

A friend of mine has a completely worked LS in a EK hatch. Thermal sounds great on that and it's turbo. If it can keep that car quiet I wonder what it does to R's.
Any feed back on APEXI n1's anybody really want to know...

 

Nice exhaust. I have one for sale if you are interested:

This kind of applies. I run a 3" TR&D on my turbo R. Obviously it will be different for your atmospheric car, but if the quality and fitment are the same as my system, you should be very happy. The only gripe I have with the system is that it's stainless, with mild flanges and mild welds, I would like to see stainless flanges and stainless alloy rod with nice tig welds, but that would bring the price up quite a bit. And I am constantly complimented on the sound.

 

That was my 2nd exhaust on my Type-R.
First I had - Tanabe Racing Medallion with silencer..that was just too loud for me.
2nd was the Thermal R and D - great sounding exhaust...nice looking too, stainless all the way.

I just sold mine and now I got 5 Zigen Fireball, sounds good not to loud compared to the Thermal.
