What diameter and length flexpipe is needed for a direct replacement of the Topspeed one?

I wonder if they just have a bunch of these already made up or if they just dont care to fix the leaking?

I am thinking I will just get a Topspeed header and go ahead and chop/replace the flexpipe prior to installing.

 

^^ I believe you need a flexpipe with a 2-inch inside diameter.

 

Does anyone know a good place to buy a replacement flex pipe?

I have the same idea as super20g.

 

I will go to an exhaust shop tomorrow to have it replaced. I talked to the owner of the shop yesterday and he didnt have a 6x2 inches flex pipe in his shop, so he ordered one and it is coming in today. He said the whole thing will cost $75. That and $175 for the header, and the total expense is $250. Still WAY cheaper than $400 DC sport header or $600 Comptech header. I dont have any other complaints about the product besides hissing flex pipe so far. Car pulls much harder past 4500 RPMS and slightly harder bellow. Sound is a bit deeper and I LOVE that. Many say that this is the best upgrade for the car along with the reflash.

PS: I am not trying to advertise anything here, I am just very satisfied with the product.

 

Ask exhaust shops around your neighborhood, they must have access to exhaust/flex pipes.

 

how much louder is your car?

 

Depends. while idling, it sounds like it has an aftermarket muffler (and idling) but once it hits 1000 rpms, it sounds like stock. Past 4k rpms, sound is not louder but a bit deeper, which I love. I have stock exhaust and cat, remember

 

Update: I have replaced the flex pipe and hissing is all gone. also, there is a noticeable TQ gain in mid range RPMS

 

wow very impressive number, btw is your an auto or manual tranny? I was thinking about that setup but with a SRI and mine is a 06 auto

 

Mine is auto. Sorry pal, but I had SRI on my old car and it made nothing but noise so I had to upgrade to CAI. As for TSX, its stock filter isnt that restrictive and there is barely any need to upgrade it unless u r going to do more upgrades (Reflash is #1 reason to upgrade it) I went with K&N drop in filter.
