Default X-pipe setup

What do you think of this setup? I just got it quoted for $300.

I currently have the FLP's with cats. I recently hit something in the road and destroyed the y-pipe so I took it for an estimate.

Fix the current problem with the y-pipe by replacing the driver side pipe from the cat to the y itself. Cut off the y at the I-pipe, weld in another y making it an x-pipe. 2-1/2" over the axle into 3-1/2" tips that have resonators built-in, 24" long.

Question - will it be any louder than the loudmouth? Virtually no mufflers or bullets; just the resonator tips. Also, going with the x and no bullets in the dual, will I have any rasp or drone?

I'm also lowered with Eibach Pro's and was assured this will hang no lower than my current setup now.

Thx, I need to make a decision quickly.

Welding two Y's back to back is worthless, doesnt function the same way as an X. Dual crush-bent 2.5" piping over the axle will also not flow as well as a mandrel 3" catback setup, so take the car to a reputable shop and have it done right.

What if they can mandrel bend 2.5"? Seriously, what are the flow differences vs dual crush bent? I understand now on the y, I can have them put in a true x. But the 2.5" was for clearance. Please, enlighten me as I've been searching for weeks and writing emails yet no one mentioned these things.

You will have better clearance with a single 3" than dual 2.5" becuase there is no great way to get the driver's side piping over the axle. Besides, mandrel bent 2.5" over the axles will be EXPENSIVE. You are much better off rebuilding the Y-pipe.

OK, I've seen pricing on mandrel bent 2.5" ( around $200 for the pipes alone ). With my setup, I think I will have both pipes go over the passenger side. Found a picture of someone on this site who did this as well, and it came out OK.

With LTs, you'd be better off doing 3" and not 2.5".

I would do a true x-pipe setup too. Once installed, it actually doesn't hang down like the y-pipe does. I think you'll be fine with your car being lowered.

Thanks DevilBird, we've been conversing for a couple of wks. on this and I appreciate your input. Dual 3" over the axles is tough, could remove the upper panhard bar for driver side clearance ( courtesy of a PSJ post ) but I autox and road race and feel that is a necessary piece of eqpt. So 2.5 on passenger side should fit fine. I am concerned with mandrel vs. crushed aluminum; any clue how much performance I'm losing? Obviously the mandrel is the way to go but for $300 I'm willing to try it for a year or so; no worse than the cost of a replacement catback ( for my starting to rust aluminized Random Tech catback ).

Well..obviously mandrel is the way to go. I really don't think you'll lose anything if you go with crushed, but if you do, it'll be very minimal. You'll gain on the top end with the x-pipe from the scavenging though <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

TrahnZam WS6, didn't you have to use some flat piping to fit on yours? And don't you have the Eibach Pro's now? I was reading up on your posts from March/April; where are you now with the setup?

Very nice pics. Your offset on the Eibach's is very close to mine as far as the drop on the front vs. the rear. I have mandrel bent now before the x going in, so it will be the crushed aluminum steel from there back. All of it will be welded as well with the exception of the cats. Fortunately I can leave the FLP quick swap design in place.

The transmission cross-member is fairly useful, and required if you want to keep a transmission in your car <img border="0" title="" alt="[Razz]" src="gr_tounge.gif" /> I would advise on not removing it, but you should check with Tony, PSJ and some other guys who have been around these boards longer than me...

There have been people that took the exhaust over the axles on both sides right? I remember seeing this on a camaro but I can't remember where it was or who's car it was. I think it was someone from Louisiana though.

How could you keep the rear end from moving and bending the pipe if you did get it to go over(on the drivers side) I am sure I could get the pipe over the rear end but I am worried about keeping it from hitting.

I have the Dr. Gas 3 inch X pipe setup.....I have turn downs right before the axel, I don't see how you could fit 3 inch duals over the axel.........another sidenote,I am experiencing ALOT of banging under the driver's side floorboard with this setup, I really dont want to have to cut up the bottom of the car like Nick suggested to me , but the banging is causing alot of false knock and I can literally feel the power loss....sounds great though
