Alrighty guys,
I took a break from modding the Dak to mod up my Renegade.
I wish to change my exhaust. Right now I got true dual 2.25in With a 2.25 Dual In/Dual Out Cat, and a 2.25in Dual In/Dual Out Dynomax Ultra Flow X-Pipe Muffler.
I wish to change it. I would not be opposed to going to True Dual 2.5in or going to a single.
I am just looking for ideas right now.
I wish to have my exits right in front of my passenger side rear tire, so length is an issue. Right now it exits at the back corners of the trucks.

For True Dual:
Should I use a crossover? If so, H or X-Pipe?
Go up to 2.5", or stick to 2.25"?
Do Cat Delete? If so, would I need an O2 sim for my 2002 4.7L?
Which muffler? Looking for deep sound that is not super loud, but rumbles nicely and sounds like a V8?

For Single?
What size? Can I go to 3" on the 4.7L without sacrificing too much bottom end?
Should I do the Cat?
Y-Pipe? Or should I get a Dual In/Single out Muffler and a Dual In/Dual Out Cat?
Again, Muffler. Same requirements as above.
Thanks in advance.

 

dynomax ultraflow is one of the best mufflers you can buy. i say keep it and just dump it under the cab. and just get a hiflow cat.

 

Well, I am not happy with my Dynomax. That is why I want to change it. When I first did it, it was nice, but the the perforated pipe must have had a week point and it began to sound like something was rattling in the muffler. I got it fixed under warranty, but now it's doing it again so I won't go back to Dynomax.

 

boo, go with their racebullet. straight thru design, its what i have. im not a fan of FM but its all personal performance. but you need to get a spintech highflow cat. i cant say enough good things about it.

 

Racebullet? Is that Dynomax?

 

yeah.

 

or just take the muffle off lol thats what im gonna do loud as crap!

 

Okay, Ill Check it out. I'm assuming this is your truck?
