The Inevitable Down Pipe Question

[RogueCustoms]

What are you running on your Mark III 7M-GTE???

I have always ran. HKS DP... BUT, I've have broken 2 at their flex joints... Yes, I'm serious!!!

Has this happened to any of you?

So now I'm thinking of going with a BIC DDP. After hearing what my 7m sounds like with a broken flex joint, I thought this would be a good idea. I love the sound of my HKS exhaust set up and I'm afraid to mess with it, given the way it sounds at idle. I watched a video or two on YouTube of this on guy with a BIC DDP and I'm not sure if it just sounded ...itty... or, it was a really bad microphone on his camera. I don't care so much how loud it gets at full boost, as long as its throaty. And as long as it sounds real quiet like a purring kitty and not raspy at idle. I like people to think... (especially the po po's) ... that I have a nothing except a very large coffee can exhaust muffler. He he

I'd just take your car to an exhaust shop and have them replace the flex section with a straight pipe. the flex section on the stock downpipe is before the the downpipe's mount to the transmission, so it wouldn't make a difference.

But if you still want one, I am very happy with my BIC rerouted DDP.

I am running a Driftmotion 3" DP to a Blitz NuR. I love it and would trade the DP for any other one. Exhaust sounds like a raped ape on steroids. lol.

Thats illegal here in Oregon........... Or so I've been told.... Why, you ask? Yea, I don't know and couldn't tell you either...

Replacing a flex section is illegal? I doubt that.

Driftmotion. It sounds great.

Quick question for you guys...

I currently have a BIC recirculated downpipe with a cracked flex section.

I'll be replacing it with an "optioned out" recirculated and coated version.

With that said, would you recommend a flex section on the new downpipe?

 

[lithium14]

I really don't see the need for a flex section unless you anticipate lots of bouncing and movement n stuff

 

[Backlash2032]

I really don't see the need for a flex section at all on the downpipe.. For reasons already mentioned in this thread.

Flex sections wouldn't break unless they're being actually used... Unless you're running solid motor mounts, keep the flex section.

I'll I'm saying is what the exhaust shop told me.... I was young... It was a bad excuse to get a new DP... Chalk it up to experience... Or a lesson learned.

Unless you're running solid motor mounts, keep the flex section.

Just to be clear - because I am using solid motor mounts, I don't need a flex section?

True, but that is where Toyota put the flex section too. Food for thought....

 

[suprarx7nut]

I'd definitely get one. Without a flex section the piping needs to be dead nuts accurate. The flex section gives you more room for workmanship error in addition to allowing movement while driving. Even a great manufacturer or builder will have some error in the piping flanges and such. That flex section helps alleviate some.

I'd say no, but it's still a good idea. Think of your exhaust as a really long lever on your exhaust studs...

I understand. I was only concerned because it seems like cracked flex sections are not uncommon on these cars.

If I'm going to drop almost $700 on a new downpipe, I don't want to find another cracked flex section down the road.

Hks divorced down pipe. I love the sound when I hit it hard. People look over quick
