LTs on a 95 w/flowmaster catback.

Anyone have any info on how i would do this? I imagine i would need to have a custom Y-pipe made to go over to the cat? (which i would like to keep)


Remember the cat is under the passenger seat, so the Y-pipe would have to run over to the right.


Anyone forsee any clearance problems or any problems for that matter.

Thanks!

You wont be able to run long tubes into your cat where it's currently located. If you want to keep your cat there, go with the SLP system(or similar) for 93-95 cars. If you want long tubes, why not consider a dual-cat y-pipe setup that runs into your cat-back?

What kind of long tubes are you getting? Also, does your year car have the dual cat setup or the single from the factory? Cuz mine is a '96 and i'm pretty sure it had 2 cats, both of them i think were on the passenger side. I could be wrong about that tho. But I got FLP long tubes installed, and it came with a y-pipe that had 2 cats, but one cat is now under the driver side. I know random tech sells a dual cat ypipe, I don't know which headers they will bolt right up to tho. I hope this helps a little.

Im not opposed to moving the cat, but i would like to keep it.


Reason im asking this stuff is the flowmaster inlet is over the passenger side axel, so a Y-pipe is gunna have to run over that direction, and im not sure if it can be done without loosing alot of ground clearance.


I dont have the car near me currently, and im bored so just trying to work things out.

Clarification:

On single cat cars---the cat is under the passenger seat floorpan.

On dual cat cars---one cat is tucked up next to the engine on the driver side, and the other is under the passenger seat floorpan.

The FLP long tubes come with a y-pipe and 2 cats that will bolt up directly to your existing cat-back. Other brands (jet-hot, hooker) require a custom y-pipe. You will lose a little ground clearance on the driver side because the pipe has to clear the trans crossmember... but if your car is not lowered, its not much of a concern.

Erg, im looking at putting in Jethot LTs.


So it wouldnt be too much of a problem to have a custom Ypipe made to work with my Flowmaster?


Thanks guys
