Down pipe choice?

Does anyone have any insight on a down pipe manufacturer suggestion?

It appears that the unit by ER is the most popular? Why?

I ask because the VRSF unit is much cheaper, but is it inferior in terms of quality and performance?

I also notice the ER and Wagner are closer to the stock unit in terms of form factor. The VRSF unit is much more narrow, which I have to assume equates to less volume, flow and most importantly HP gain.

Any insight is appreciated!

Thanks!

A brand new catless downpipe can be had for $170 if you know where to look.

Although a pipe is a pipe, you may run into fitment issues.

Do tell...

I'm checking the classified section daily. I'm leaning toward ER/Wagner.

I went with VRSF. Great fitment and sound. Wanted a reputable brand but saw no reason to pay more.

Catless = no catalytic converter which will trigger a CEL.
You will still have the holes for the oxygen sensors as would an OEM.

If you're looking to avoid a CEL yet still gain an awesome amount of power, I would check out our Sport Cat Downpipe. Guaranteed no CEL. Bolt it on and go have fun and no tuning required.

I went VRSF as well. 100% fitment, performance gains are most likely similar to ER. Been running for more than 13,000 miles with no issues at all.

+1 VRSF. i feel like people have some sort of unwarranted personal vendetta against those guys. I have their catless DP and charge pipe, great fitment and zero issues at all. Stand up company if you ask me, just as reputable as ER or Wagner. Feel free to provide factual data to prove otherwise.

As others stated above, a pipe is a pipe. I went with VRSF had no fitment issues and love the sound.

Due to the fumes produced by catless DPs, I went with Wagner's CATTED DP. Irregardless of which manufacture you choose, you'll need to take under consideration the following points:

- cost of catted vs catless
- performance
- sound differences
- fumes

For my catted Wagner, I am pleased. There is no smell what so ever. Performance wise, it rocks with my FOB setup and the warm up sound on my MPPK exhaust is awesome. The only complaint I have, the placement of their O2 sensors are on the far reaches of the OEM O2 cable length.

Ok, so catless, I will likely go with the VRSF. I'm glad the topic of fumes was mentioned, because this is a concern for me.

With catless are the fumes rediculous? Potentially dangerous??

I know that catted is considerabley more costly.

Why do most go with catless? Purely cost savings?

Going catless will absolutely result in smells of exhaust fumes. Are they dangerous? Not unless you are sitting there breathing it in all day.

Most people go catless for cost savings, yes. They also go for it because you will get the most sound and power from a catless setup. Now our Sport Cat Downpipe has been proven to provide about 80-90% of the power and sound of a catless setup, without needing to tune for it. And best part, ours does not trigger a CEL.

Check your PMs, I would love to chat more!

The gains with catless are significantly higher than catted.

As far as smell/fumes go, you'll only smell fumes if you're idling in a garage while parked with the windows down. If the downpipe is properly installed without any leaks, there's no smell to worry about when driving.

This is just my humbled opinion, but owners of catless DP who tell you it doesn't smell, is in denial. LOL. You can smell a noticeable difference between between the two. Catless owners typically go that route due to cost and performance. Catted DPs are literally twice the cost and their performance is slightly less than a catless DP.

In the end, it's your judgement call. If you go catless, you'll eventually get use to the smell while pocketing the extra $$$ you saved.

I park in my garage and daily I can smell fumes on start up and parking on a daily. Everybody is different and have a different tolerance. I came from driving a 65 mustang coupe to a 66 fastback so this little gas smell is nothing to me lol. I might add I've had plenty of girls ride passenger with me and never has one complained yet mentioned the smell so it's not that bad.
The change in sound is like night and day. Sounds wayyy better. Just go catless. I went with ER but any manufacturer will have the same results I'm sure.

On the topic of smell--there for sure is a smell. In the car with windows up there is none, but at a stop such as a red light with any light wind going to front of car the smell will waft in. And when you park you will smell it for a second, especially if you go to the trunk. As for how bad is it? To me the small sacrifice for an odor is well worth it.....little side story:

My prius driving, extreme environmentalist father in law was driving with me a month ago. The next day he E-mailed me and said he smelled exhaust fumes from my car when we stopped..like untreated exhaust. He asked me, "did you remove your catalytic converter?" And he said your car seems louder than before. I knew where this was going.
I told him, I coded a part that made it so some exhaust gases go out a blowoff valve from the turbo to the exhaust. And, I said I run e85 which makes these cars run better but makes it smell like a diesel a little. He asked if it was legal and I said of course.
