LTH on Sedan
First of all, has anyone gone down the LTH route for a sedan? I am looking to buy a full FI exhaust setup. FI are in the unknown if it would fit the sedan. The infiniti part #'s for stock manifolds and cat conv is the same in the coupe and sedan.
Does anyone have any insight into why it won't fit? :11: |

The coupe HFC's are 2.50" ID, and Sedan HFC's are 2.25" ID. I can only assume this is because the sedan exhaust from FI is also 2.25", while the sedans is 2.5". I'm guessing that the LTH's are also 2.5", meaning you'd be taking an ID reduction from headers to catback.

FI makes a 2.5" at the cat and catback for an extra $100.

+1 on this. I've got a full 2.5" RHFC and non-resonated CBE setup on order for my sedan. Hopefully it'll be here soon. I've been chomping at the bit to get this thing installed. It should sound pretty nice. It's going to be loud but I don't mind that. :)

are you sure? i know you can use sedan and coupe cats interchangably, even 370z cats, and Y pipes for that matter. that doesnt mean they are the same diameter, but i was pretty sure they were all 2.5" for aftermarket

I got an email directly from Tony at Fast intentions telling me about the ID difference

I think it's the route FI chose to take on the sedans since they assumed majority aren't interested in max performance.
yeah im 95% sure my sedan HFCs are 2.5" possibly bought them from a coupe owner though :dunno: |
I don't see the point of replacing any exhaust component with anything aftermarket that is 2.25"
