Hey guys, so I recently bought a Greddy Ti-C exhaust (for Civic Si 06-09) and it turned out that the muffler was scraped and the hole was welded up. Will a patched up hole affect the performance of the muffler (or will it start to leak)?
I've been wanting the TiC for the prelude, but I don't know if I should try and sell this one and buy a new one online or not?

 

Unless the dent creates a choke point restricting the diameter of the flow out. I dont see how it could effect performance. On the other hand it may effect tone, since thats a sound dampening resonating chamber.

As long as its been patched closed it should work fine. Can you see the dent when its on the car? Its up to you, if its a show car get a new one. If you are stuck with it put it on. I hope you didnt pay too much and got shafted by someone...

 

if the weld has a good seal then it should be okay. but to my suggestion truthfully Id buy another when the chance comes.

 

Well it's still sitting in my room, so I don't know if the dent is noticeable when on the car. And it's just for my dd so I think i'll keep it unless I get a buyer. I mean I paid 300 for it, so I don't think I got ripped off too bad (or at least i'd like to think). Thanks for the input guys
