So which downpipe would work best with the Greddy Titanium catback exhaust? Meaning best fit and performance?

 

you want a 3" downpipe that will fit nice. you can check out the following: Perrin, UR, TURBOXS, HELIX and many others. a 3" downpipe is a 3" downpipe. they all do the same thing so just choose one that you like or one that people seem to be happy with. btw, very nice choice on the catback. i am sure that you will be very happy with it.

thanks

I've got a 70mm Fujitsubo DP with mine. It sounds great.....without the silencer it's not too loud and very deep and bassy. It sounds totally different from the clips on Road///Race's website.

The GReddy Ti is by far the best exhaust I've ever seen and heard and bought

 

The GP Sports 76mm dp very nice build quality... you will need a high flow cat or a cat delete. I'm using GP sports 73.5mm cat-delete.. The idling is a very nice low but solid continous rumble (unlike the scoobies) and low rpms are nice... High RPMs are loud (4K above) and you will hear the tone change from a rumble to a strong and loud throatty scream. BUT you have to remove the front lower torsen bar because the DP is too big... I've not dynoed the car since i put it in but i can notice the different which means its quite a fair bit of increase.. maybe between 20-40 including the tuning.

 

Do some serious research...3" Downpipes are not all the same. Here are just some of the issues I could think of quickly:

Clearance of underbraces
Oil Pan clearance/closeness
Flex Joint or solid
Retain Donut Gasget or not - exhaust leaks?
Finish Quality/Texture
Guarantee/Price
What comes with DP - Gaskets?

There's probably more questions to ask and answer

 

Does the 70mm Fujitsubo DP bolt to the stock cat and can upgrade to 3 inch later? Are you running the stock cat? 'Cause I know the Greddy Ti can bolt to stock cat and probably bolt to 3 inch later.

 

Does it also have the donut gasket?,the Fujitsubo.

 

Not all downpipes are the same. Is it full 3 inch with no neck down? Is it stainless? How is the fit? Does it come with the gasket you need? Does it include the cat delete? Does it come with spacers and longer bolts for the subframe braces? Will it trigger a CEL? Does it have a lifetime warranty? All these things we looked at when we designed ours.
