Custom LT4 Cat-back
Well, the time has come to build my exhaust for the 96. I have always been impressed with the quality and sound of magnaflow over the years, but it has always been too expensive, and magnaflow doesn't even make a full cat back for the C4. So I have decided to make my own. It will not be the first time I have made exhaust and I am pretty handy with my 220 mig. I am about to order the parts, and I would like your guy's opinions before I start.
I have EM 1 5/8 headers on the way, and I am going to create my own cat-back from the headers back. All 3", all mandrel bends. I am getting the piping and mufflers and X from summit.
I am using a stainless X-pipe section from magnaflow (shown below).
I was originally planning on running these muffers (in stock location) with the stock LT4 tips to retain the stock appearance from the rear.
But, while looking around for different prices I ran into this muffler that magnaflow sells.
And I was thinking that I could run pipes through the X and then almost straight into the dual/dual muffler before the pipes split near the dana. Like this:
Should I run it through a magnaflow dual/dual muffler or run seperate bullet muffers in the stock locations?

Be sure to check the centerline spacing on the Magnaflow X-pipe....
I bought one a couple years ago and it did not match the spacing on my B&B exhaust......
BTW my exhaust has the B&B resonator and a true H-pipe I added to it in the same location as the stock LT4 H-pipe and no mufflers.....the resonator does act a little like an X-pipe as the two pipes are not isolated at all inside the resonator....might be true of the Magnaflow mufflers...

[QUOTE=96Eric;1559517694]The distance between the X pipe and the dual outlets on the mufflers are both 5.75 according to magnaflow. Which way would you do it? Seperate mufflers, or one big one?[/QUOTE]
One thought is that one muffler/resonator would weigh less than two mufflers, probably cost less than two...
.....and that is what I have.....one resonator/no mufflers
Really don't know for sure which is better..
