Right now im running JDM headers, 2.5" test pipe, itr B-pipe, and Greddy SP muffler. I know its a weird setup, long story.....Anyways, you guys think i should replace the itr b-pipe for the GReddy one? Im not real sure.....I like the itr one because is OEM quality, but the only thing i dont like is the bottle neck on it. The opening of it is only like an inch or so big, so it kinda makes the 2.5" test pipe useless. I think the GReddy one is 2.25" all the way.......wat yall think??

 

Will the greddy bolt on? If so, sure. The type-one makes a 2.5 bolt on b-pipe.

 

From my understanding, the Type-1 isnt 2.5" all the way through either.

I would use the greddy pipe

 

Steve is right...sadly. there is a bottleneck in it, it tapers down to less than 2".

Ross - who is taking his Type One to SMSP to have it chopped up pretty soon

 

I think Greddy makes one of the best exhausts for street applications and tend to get overlooked, by the hard core folkes. Go greddy.

So is the Greddy 2.25 all the way for sure?

 

Yeah im pretty sure its 2.25" all the way thru. I just wish the itr b-pipe didnt have that damn bottle neck on it.........oh well.....i guess im puttin the GReddy this weekend......yall think it will be a big difference??

 

The greddy is 60mm which is roughly 2.362 inches..
Get the Greddy piping.. thats what i use.. it has been on my car for 5 years and i cant complain... i almost replaced it recently with 2.5 inch piping, but the gains for the price of mandrel piping isnt worth it.. I thought of getting push-bend 2.5 inch piping, but realized the greddy is better, considring there would be boltnecks on the push-bend piping..

 

I'm currently in the same dillema with my Sibus. I've got an old black canister RSR cat back which I'm thinking about swapping out for 2.5" custom exhaust. I'm trying to weigh the costs vs benefits

 

where can i buy just the b-pipe and how much? Most of the place only sells them with the muffler.

And is this the biggest straight-through b-pipe that i can buy?

 

Agreed, I think that the Greddy SP, although an old design is a good exhaust for a street application. I had an SP cat-back on my 96 GSR sedan and it was excellent all around.

 

you can sometimes find people getting rid of their greddy b pipes for $100.. i would pick one up if i were you..

 

You can also pick up a cheap stock b pipe and remove the restrictions..

Craig - Who was going to do this but got lazy

 

Wait a minute, so u guyz are saying it replaces the factory b-pipe??? Its the same lenth and its a simple bolt up matter??? I never knew that..

 

how do u remove restrictions?
