Hi. I have a quick question about flexpipes. I am planning to upgrade to 2.25" like everyone suggested and in the course of buying parts bought a 2.25" flexpipe since I hear you can get leaks in your header gasket area if you don't use one.

The flexpipe has some open gaps where it looks like the exhaust might be able to escape before it reaches the cat/rest of the exhaust. I was wondering if this was ok ... also if these small gaps would result in a whistling noise or something? Or maybe this is just normal for a flexpipe since I never seen one up close before.

Also, where the outer tubes have been welded onto the flexpipe ... the outer tubes are 2.25" but where they were welded on, it bottlenecks down. It's hard to describe, but it looks like the tube has a smaller diameter at that end, was inserted into the flexpipe end, then welded. So there is a part on both ends of the flexpipe where it bottlenecks down. On the inside, I measured the diameter and it was a little under 2" ... around 1.9" ... but most of the flexpipe is infact 2.25" in diameter. It's just where those two outer tubes are welded on that it bottlenecks to under 2". I am hoping this is normal and won't restrict the airflow? Or would it somewhat negate the point of upgrading to 2.25" wide piping if there are chokepoints like that? If it does restrict airflow, could someone who bought a true 2.25" flexpipe recommend me a good place to buy one?

thnx everyone :o)

Well it probably shouldnt bottle neck like that because once it goes from to 2.25" down to 1.9" thats restricting exhaust flow back down. your can buy flex pipes pretty cheap on ebay. Ebay Flex Pipes
it shouldn't have anykind of restricting baffles inide there it should be a 2.25" pipe into a wire mesh type pipe back into a 2.25" pipe. you should be able to see right through it.
