I installed resonated test pipes on my sedan last night and I lost a lot of low end torque, and now my car sounds like a subaru sti -_-

I didn't think I would've lost that much power with stock muffler, coupe midpipe and HR y pipe.

 

cool story bro.

 

Which test pipes did you install?

 

I have the stock cats, and a custom true dual exahust system from the Cats back. I had the stock split pipes coming off the Cats, flowing into a magnaflow X pipe, from there i had 2 > 2.25 pipes ran straight out to a 2 in / 2 out magnaflow, Stainless high flow muffler, with custom tips. Oh yea, forgot to tell you, lost the resornators / straight piped through to the Magnaflow muffler. Good throaty sound, and it really turns heads when you throw it into manual-auto 2nd and punch it, run it up to about 5800rpms, and shift to 3rd, Dude! no loss of anything.

 

:jamin:

 

Some generic ebay ones lol They're really big tho, maybe that's why I'm losing so much

 

No you are losing power because your tune is off. Going for stock cats to test pipes is a big change. Your AF ratios are way off. My car felt slow with HFC, once I got the tune, big difference in low end power

 

Gaskets were broken so replaced them with the oem ones. No more leaks. Here's how it sounds:

That's one of the problems with test pipes, you will lose a ton of torque, just a sad fact of life with them

Only exception i've seen are the ART pipes from Motordyne, they still lose a little torque, but nothing like normal test pipes.
