So as you can read in my signature I’ve already done a lot of cheap things! (Am still students, that’s why ned goes so fast, from 1.7. am I with the Bundeswehr if everything goes well!) To the tuning: I had a few questions: 1.) I want an L + R exhaust system! But make the open air filter ned out! What do you advise me? Are there possibilities? Do you have experiences? 2.) How sure do I get the wing doors of TSS Tuning registered??? What does that matter?? ( www.tss-tuning.de * horny Honda Tuner*) 3.) What does this look like with air hats in the bonnet? Are there which ones I get registered? If so where and how much do they cost? 4.) Do I have to take out the back seat when I install sports seats?? Are there any ones that do not apply? 5.) I had a lowering (about 30 – 40) before AND new rims! no more 14 ́ ́ but 16 ́ ́ ́, what to consider, is the TÜV – Technically possible??? I also heard I then have to register my sports steering wheel, at other 6.) Last but not least I have another question: I guess I have between 125 and 140 hp in the mom, I want more like all of you! How is it best?? If all possibilities are possible? Costs don’t matter! Can I install every engine with 1.6 ccm? Is it realistic if I want to be on the road with about 300 hp AND a TÜV approval?? Thank you for your answers already in the front!! ByE S imon
