my car has a HKS downpipe and ebays exhaust, since 2 days ago, once i start the car, the sound of exhause is louder than before, all my friends can tell too, im not really sure where the problems is, cuz the exhause was from ebay, so when i hooked it up, they said the exhause was like 2-3 inches off. can anyone tell me why my car sound way louder than before? for me, i think its the gasket betweenthe downpipe and the exhaust. Thx for the help
probably the gasket between the downpipe and the cat back i had that same problem with my bosal helix combo. I picked up a gasket that had a edge on it from an exhaust shop in wisc that Justin had gotten his. put that gasket on along with the oem gasket and no more exhaust leak! sorry if that is kind of hard to understand.
I would have to agree. DP to mid-pipe leaks are common. easy fix though. make sure you gasket is centered between the pipes and retorque.
Check the ebay exahust for cracks. I have seen two come through my shop the have had cracked exhaust. Both came from ebay. But I hope its just a gasket for you.
thx guys...actually, when i started my car, i kinda can see the gasket between the DP and catback is goin back and forth, seems not tight enough, and when its cold, i can see the smoke goin out from the gap. what can i do now, can i go to any dealer and buy the gasket, cuz im using the gasket came with the exhaust, is it possible that i put couple gasket on the cover the gap?
yea the dealer has gaskets, otherwise i could see if justin can post a pic of te gasket that i got and i can post how you can get one.
here is a crude drawing of the gasket. sorry im not readymixx when it comes to the mspaint the dark outline represents the part of the gasket that protrueds and seals the diameter These can be purchased thru the muffler shop in wisconsin I will have to wait till justin gets home to get the part number for you. Otherwise you can call them 715 386-1560 and see if they remmeber me ordering mine. Just ask. The last name is Peterson I think they are $8
thx for the help!!! but im not sure how way off between DP and cat back ... u think its gonna fit the gap?
yea...thats what im hopin too otherwise i have to get a new cat back and yea cheap stuff always sux, my friends said the exhaust doesnt need to be a brand name isnt that true tho?also whats the different between cat back and turbo back?
Turbo back comes with the down pipe. The stuff is cheap but it works. I have the ebay turbo back exahust on my car and its fairing good.
or you can cut, sleeve it and reweld it... done a few of them... after all I do own an exhaust/auto shop... cramming extra gaskets is ok for temp fixes....
can u look at my car if u have a chance? well my exhaust sound becomes as usually somtimes, which mean suddenly not loud at all, do u think thats the problem of gasket?
