[Joel Munoz]

Which one should I install first, Downpipes or a Cat Back Exhaust?

Downpipe

 

[Zpak]

Downpipes all day.

If performance is your goal then downpipes. If your not planning to tune your car then maybe exhaust.

If you're not planning on a tune save your money and do maintenance.

Downpipe, seems Corsa catback will give you rasp with downpipes. My PPE catted will be here in 2 weeks. I already have MRT axle back with resonators due to drone issue. If I have rasp after downpipe install, I'll update and let you know mrt is as faulty for rasp with aftermarket downpipes. I've kept my stock mufflers in case of rasp issue, downpipes are for earlier spooling and torque staring at lower rpm. Best benefit.

Downpipes, I had mine put on worth the money!

 

[Joel Munoz]

All good points. Which brand on downpipes is best to install on a daily driver?

 

[DadMobile]

PPE would be the best.

 

[Joel Munoz]

Are PPE downpipes just for racing only or can they be used on regular streets?

CATLESS ONES LOL i live in the middle of nowhere so theres no emissions and if you do downpipes with turndowns it'll save you a ton of money on a catback....you'll need the money later for hearing aids after driving it for an extended period of time.

Downpipes, I personally like the sound of downpipes with the stock catback. If you want more rumble add a Magnaflow resonated X-pipe in place of the stock crossover and resonators and it'll sound great without being ricey.

I was reading about the PPE downpipes thru the net and said that these downpipes is for Racing Competition only and is not legal for use in highway or street vehicles or other non-racing competition off-road vehicles. Is that true or can I use PPE on public streets or highway?

They come with Magnaflow EPA certified catalytic converters. I would guess this is more of a CYA than anything. If the converter truly passes EPA certifications, it is legal. However, by putting this warning on their product, they cover themselves if for some reason it does not pass or you do something wrong installing it or you modify it.

Not to hijack the thread, but when looking at PPE and Stainless Works, both catted versions, what makes up the ~$600 price difference between the two? Is there really a big difference in quality?

Downpipe and a 3rd cat delete otherwise you'll have horrid rasp, I replaced mine with a magnaflo xpipe/resonator and it sounds great.

Converter and construction quality. I can't confirm what converter the SWs use, but 9/10 times they still pop a CEL.

Also the PPEs are hand made, where the SWs are done on an assembly line by a robot.

Wanting to see if you have after market already? Stock will look brown and rusty. Aftermarket will look smooth, stainless look.
