Absolutely not. The muffler controls tone, sound, and loudness. I suggest going to a local exhaust shop for a custom bent up system. Something like a Flowmaster Super 44 with a single inlet/dual outlet and dual tailpipes. That's what I'm running and the entire system from the last cat-back, and it ran me about $250 including muffler.
You're very limited since you're trying to reuse the stuff muffler and it's sizing. Why you want to reuse stock muffler is beyond everyone here. We don't even know anything about your truck....generally stock piping is 2" or 2.25".
Please create a signature giving us a little bit of info about your truck(year, engine, trans, 2wd/4x4, trim package, modifications, etc). Help us help you!!
Like I said above, you're limited in options because of the stock sizes and what you're trying to accomplish. Most the good looking and the correct Y-pipes are far too large for stock piping...use of those will require possible over expanding of the tubing to make work.
I still vote for a complete new cat-back system with a better muffler. Custom bent and hung by custom exhaust shop.
In my eyes it is lol. Im a tight ass. I spent less money on my muffler!
Anyways, I agree with what everyones sayn on here. Your stock muffler will do you zero good. If your gonna spend the money to run a y-pipe, might as well spend an extra $40 for a good muffler
Put a Magnaflow cat-back dual system on my 04 XLT 4x4. Here are some before and after pics wish I could download the sound video but it won't download to the site?
