Just wondering if Top End Performance parts are any good. I am currently rebuilding my turbo and figured it is a good time to just put in a new downpipe and delete the secondary cat and the secondary air filter while I'm at it. I've seen the Top End Performance down pipe options but have seen a few comments in various places here saying Top End Performance parts aren't the greatest, bad welds were mentioned I think. My other option is to get one from ebay or I am open to suggestions

Top End has good quality parts....People make negative commnets because they are usually over-priced...

You can find a Mookeh/MK1 downpipe on ebay also...

I had a Top End Performance downpipe on my car and the lower flange rubbed on the transmission bellhousing. If it were welded the opposite direction it would be fine.

Is there any reason to go with the 2.5 over 3"? Like would the 3" be bolt on or would i have to upgrade the whole exhaust to 3"?

Don’t go 3” unless you plan to make the whole exhaust 3”.

Depends on your plans for the turbo. If you are planning to run a bigger turbo with more boost then a 3 inch might be something to consider. I'm running a 14G, which isnt much bigger than stock 12a, with a 2.5 all the way out the back and it seems to be a decent setup.

Thanks, yeah at this point I'm just gonna keep the exhaust the same size. 2.5" Mk1 with flex looks to be the deal then. Thanks for the help.

My friends 88 is pushing little over 380hp  with 2.5 exhaust all the way back.Its not even mandrel bent or anything. Just to give you idea.Mk1 downpipe = good   mine was a little to close to the transmission so l ended up cutting and re clocking the flange to my liking (it would have worked fine the way it is though) but l had this need to cut and weld something LOL.
