ATTS vs NON ATTS exhaust downpipe

Hello. I have a -98 Prelude VTi-S (ATTS) and I'm going to buy a new exhaust manifold+downpipe. I know there is some difference between the atts and non atts prelude downpipes. Here is a link to a SRS header that im about to buy:

https://www.akr-performance.com/p/sr...-HPH-PL97421SV

The site says it should fit to my 2.2 VTi-S, but it does also fit to 2.2 VTi (non atts) model. Is that possible? Can there be a downpipe that fits to both models??? When I checked some US sites and ebay, they listed non-sh and sh headers differently. :s

Thanks.

Re: ATTS vs NON ATTS exhaust downpipe

why youre buing new manifold? you know that kind of manifolds are pure oem replacements so no power gains?

some headers fit both models - they come with short connecting pipe that you can fit the Base header to SH models since their downpipe is little bit longer (thats why theyre listed differently)

and you can also make em fit - needs only cut & weld

Last i checked, here in the US base/Type-S have a shorter down pipe vs SH model which has a longer down pipe.

Because of ATTS they needed to make the downpipe longer for those models
