Noob exhaust question

[Bobblehead]

Pretty bad. These cars get pretty loud and super raspy when you do the exhaust wrong.

Well what is doing the exhaust "right?" With cats?

[Bobblehead]

With cats and/or resonators.

Edit: Basically if your exhaust doesn't drone or have rasp, you've done it right. That's what I was trying to say.

Which part in my proposed set up would add rasp?

[Bobblehead]

The front pipe with no resonator or cat.

Do you think just sticking with the stock front and over pipe would be a better option?

Yeah. There aren't that many gains to be had from the front pipe if you've already done the headers. If you do decide to get a front pipe, I'd at least get one with a high flow cat and/or resonator to keep things civil. Don't underestimate how loud catless headers are - if your catback is already loud, adding catless headers to the mix will be a bad time.

So, forgetting the over and front pipe, do you think even going with just the JDL UEL header and j2 quad tip catback will be raspy and loud?

Having heard that very combo in real life, it is not raspy at all. It is very deep and very loud though.

So, my question is, can I use the stock piping in between the two and have no fitment issues or do I need to purchase new piping and if so, what parts do I need to purchase? Thanks and sorry for being a noob.

Have a read here

Suggest you leave stock catback on if you have not already bought one.

Change to catless header and tune this will get you the best power\torque gain

and you will get a bit more sound

if your keen later on chamge overpipe and get a high flow catted front pipe. you wont need a retune for those changes.

this will net you slightly more gain but will also increase volume due high flow cat.

if you change catback with catless header and hi flow front pipe its going to be loud and generally raspy.

to avoid being loud and raspy keep either stock catback or stock front pipe.

if you like loud then change both but get a quiet catback like invida Q300 or similar elsecit will be rearly loud and raspy

Thanks, steve.
