hah i know what you mean. just when you are expecting perfect you end up with ebay. if just return it. Like you mentioned, you spent good money on it. you SHOULD deserve quality. otherwise why spend the 3x amount over an ebay product. right?

 

Shoulda but didnta

 

Talked to Cobb again and they had no answer for me....again. I'm not too happy with the problems with this downpipe or the customer service from Cobb, could have bought a cheaper DP and saved my self some $$. Next time Perrin or Invidia will get my money

 

1. Check out the grimmspeed dp. Its bad ***.
2. Check out some tranny mount options. A stiffer trans mount means less wiggle...

 

This freaked about cobb and you're talking about perrin and invidia. Lol.

 

+1.

 

+1 on Grimmspeed. Every item of theirs I put on my car is spot on. Not the cheapest, but all that $$ goes into the design of a superior product.


If you're going to stick with the Cobb, a fix might be to take off that tranny mount bolt and see how the DP hangs w/o it. Determine how much additional space is needed to prevent the rattling, then have an exhaust shop cut and weld a piece of metal spacer-type thing for that mount so it stops rattling.

 

Are you 100% positive that it is for your car and not a 02-07 Wrx, could have shipped you the wrong one

 

Bought it from a member with an '11 wrx so I'm sure it's the correct one

 

Sorry but what does that prove? Did it work for them or did they have an issue as well?


I've found Cobb to be VERY reasonable with customer support. But it's difficult for a company to deal with every issue that comes up with a used part. Do you have a receipt? A confirmed history on the part... i.e. was the car it was on in an accident, did it ever fit right, etc. You need to understand that some of these parts get passed around like $2 hookers. Companies just can't be expected to fix all these kinds of issues. Sometimes they will sometimes they won't.

If you are having issues with fitment and can't figure out how to make it work then I suggest you stay the hell away from Perrin. They're notorious for poor fitment and poor customer service. Invidia... LOL! If you're looking for a new one... everything I've seen on the grimspeed is legit. That thing looks dope. It's probably the one I would personally get.


Try getting hangers or building a bracket. It usually doesn't take that much to get things like this to line up a little better. Heck my exhaust has a couple different length solid hangers on it to keep it from knocking around.

 

You could loosen all the bolts up in the exhaust system (uppipe, dp, stock exhaust) and try to realign the system some. There is a good amount of play through the whole system.

If you want a faster solution you could grind where its hitting at or hammer a dent into the piping to keep it from making contact. You could also torch the dp a little and bend it some with a pipe.

If you decide to replace it, I would go with a grimmspeed one also like others have mentioned. Ive had their catted and catless dp and they are quality. Their customer service is top notch also.

 

Motor mounts and trans mounts are good? Had a similar issue on a GSX eclipse 10 or so years ago, that was my problem. Didn't notice how bad it was until I put a much larger DP on.

 

So this is somehow Cobb's fault when you bought it used from another person?(assuming it had no issues on his car, if it did then that's your problem buying used, if it didn't then it would be something to do with your car) I'm confused.

 

This thread makes me love my Crucial Racing DP even more.

 

I am going to have to go with "you bought it used, how the hell is it cobb's fault" here.

It sounds like somthing is off with your car dude. I have a cobb catted downpipe on the FXT and had ZERO problems with fit.
