I'm quite curious about downpipes for my 2.4. I've read that a 2.5in would be perfect for NA 2.4's but is there a noticeable difference in performance, compared to stock? I know there's one in sound lol. Just trying to do little mods here and there. And is anyone selling one by any chance? I can't seem to post in the classifieds because I'm a new member I'm guessing. Thanks!

 

You won't notice any real power gains with just a downpipe honestly. But yes the 2.5inch is good.

 

I have one. It's 2.5" and catless. For a manual. Is yours auto or manual? I loved having an aftermarket dp. It made the car feel better on the butt dyno for sure. I drive a ss/tc now so my old zzp dp doesn't work. But my catless zzp dp for my lnf will be here soon.

 

Mines an auto, wish I had a manual haha. Kinda want a DP now. A DP with a CAI, do you think I'd def notice a gain? I've read that DP adds about 10HP or so. How do you like the TC?

 

Don't waste your money you won't see a real noticeable gain save your money and add boost to your ride.

 

LOL I wish I could, I'm better off buying a TC/SC coupe then getting a TC/SC kit for my car.

 

I put my s/c kit together 1300 with bigger fuel and tune. get a few parts at time and no extras just stick with what you have to have.

 

I thought it was worth it. A tune really helped. I love the tc. It's a totally different animal. Obviously. Lol. But I love it. I also loved modding my g5 though.

 

Maybe if my car didn't have all the miles it has on it already, I'd highly consider SCing it haha

 

I shall look into it more! I bet! They look sweet. Def. wanna get one or a SC coupe.

 

You will be sub 200whp with a fully bolted and tuned 2.4. If you want it to be pretty quick sc or turbo it.

 

Mine had a GMPP intake, and I put a header and LSJ downpipe as a cheap fix/upgrade to the broken flex, and my car pulls much harder now than before and spins in second

 

Thanks for all the inputs and help guys! I'll probably buy a DP within a few months.
