Heres the background. Started the car today, and noticed that Im running a bit rich (gas "popping" out of the exhaust). Also noticed to the left rear tire, where the exhaust is, its dripping gas out (exhaust leak)

 

Thinking of re-doing the entire exhaust from the Y-Pipe back...

 

I think it was some off-size, like 1.5" or 1.75" which goes up to a 2.5" cherrybomb muffler..

 

Questions:

 

- Can I go to a 2" pipe from the Y-Pipe back or do I need a custom Y-Pipe?

- What are the effects on the Cherrybomb sound? - Quieter, Louder, Same?

- I need to get the piping bent, do I need to take in my old exhaust or is there some kind of schematic somewhere that has this information on where it needs to bend?

 

Thanks in advance!

keep the stok y pipe. Run a 2 inch cherry bomb right after the y flange, and straight pipe out to the tail. you can go 2 1/4 for the tail piece for ore sound.

 

I like my exhaust this way, it keeps the torque, and it is quiet unless you are revving the heck out of it, and then is sounds mean! It will idle very quietly.

 

If you make a header, stay with 1.75 inch to your collector

Don't go too much on the exhaust until you fix the richness issue. I blew up a $400 exhaust system that way

 

My system was full custom, 2.0 ID to the cat, 2.25 to the muffler (40 series delta flow flowmaster, I think offset input centered output maybe) and 2.5 out.

 

GLCraig MAY still have the exhaust system (the good one, not the blown up one).... last I knew it was in his storage unit.

 

Its ONE piece and was technically made for a wagon, but may fit a sedan IF its even still around... It seemed to go through exhaust gaskets not having some kind of flex joint though... or maybe my exhaust studs just sucked
